Summary
Multiple cross-site request forgery (CSRF) vulnerabilities in TRENDnet TEW-812DRU router with firmware before 1.0.9.0 allow remote attackers to hijack the authentication of administrators for requests that (1) change admin credentials in a request to setSysAdm.cgi, (2) enable remote management or (3) enable port forwarding in an Apply action to uapply.cgi, or (4) have unspecified impact via a request to setNTP.cgi. NOTE: some of these details are obtained from third party information.

Summary
Multiple cross-site request forgery (CSRF) vulnerabilities in TRENDnet TEW-812DRU router with firmware before 1.0.9.0 allow remote attackers to hijack the authentication of administrators for requests that (1) change admin credentials in a request to setSysAdm.cgi, (2) enable remote management or (3) enable port forwarding in an Apply action to uapply.cgi, or (4) have unspecified impact via a request to setNTP.cgi. NOTE: some of these details are obtained from third party information.

Vulnerability from variot
Buffer overflow in Broadcom ACSD allows remote attackers to execute arbitrary code via a long string to TCP port 5916. This component is used on routers of multiple vendors including ASUS RT-AC66U and TRENDnet TEW-812DRU. The ASUS RT-AC66U is a dual-band wireless router. ASUS RT-AC66U Broadcom acsd Wireless Channel Service (Wireless Channel Servic) has multiple buffer overflow vulnerabilities that allow remote attackers to exploit a vulnerability to submit a malicious request to stop the device from responding or possibly execute arbitrary code. ASUS RT-AC66U is prone to multiple buffer-overflow vulnerabilities. Failed exploit attempts will likely result in denial-of-service conditions. The former is produced by ASUS, and the latter is produced by TRENDnet in the United States. Broadcom ACSD is one of the wireless channel service components. A buffer overflow vulnerability exists in the Broadcom ACSD component used in the ASUS RT-AC66U and TRENDnet TEW-812DRU. #!/usr/bin/env python

Vulnerability from variot
Multiple cross-site request forgery (CSRF) vulnerabilities in TRENDnet TEW-812DRU router with firmware before 1.0.9.0 allow remote attackers to hijack the authentication of administrators for requests that (1) change admin credentials in a request to setSysAdm.cgi, (2) enable remote management or (3) enable port forwarding in an Apply action to uapply.cgi, or (4) have unspecified impact via a request to setNTP.cgi. NOTE: some of these details are obtained from third party information. The Trendnet TEW-812DRU is a dual-band Gigabit router device. Trendnet TEW-812DRU is prone to a cross-site request-forgery vulnerability. Attackers can exploit this issue to perform certain administrative actions and gain unauthorized access to the affected device. A cross-site request forgery vulnerability exists in the TRENDnet TEW-812DRU router with firmware version 1.0.8.0

Vulnerability from variot
Stack-based buffer overflow in the run_init_sbus function in the KCodes NetUSB module for the Linux kernel, as used in certain NETGEAR products, TP-LINK products, and other products, allows remote attackers to execute arbitrary code by providing a long computer name in a session on TCP port 20005. KCodes NetUSB is vulnerable to a buffer overflow via the network that may result in a denial of service or code execution. KCodes NetUSB The kernel driver contains a buffer overflow vulnerability. KCodes NetUSB Is Linux Connected to base embedded devices (home router products, etc.) USB Share devices on the network "USB over IP" To realize the function, Linux Kernel module. Buffer overflow (CWE-120) - CVE-2015-3036 http://cwe.mitre.org/data/definitions/120.html The client NetUSB The data to send when connecting to the server NetUSB A buffer overflow can occur because the kernel driver does not validate properly. For more information SEC Consult Please check the advisory for. SEC Consult Vulnerability Lab Security Advisory < 20150519-0 > https://www.sec-consult.com/fxdata/seccons/prod/temedia/advisories_txt/20150519-0_KCodes_NetUSB_Kernel_Stack_Buffer_Overflow_v10.txt In addition, National Vulnerability Database (NVD) Then CWE-119 It is published as CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer ( Buffer error ) http://cwe.mitre.org/data/definitions/119.htmlAn attacker on the local network caused a buffer overflow, resulting in a denial of service operation (DoS) An attacker may be able to attack or execute arbitrary code. Depending on the default settings of the device, a remote attack may be possible. KCodes NetUSB is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts may result in a denial-of-service condition.

Source: http://www.kcodes.com/
Vulnerability overview/description:
NetUSB suffers from a remotely exploitable kernel stack buffer overflow. Because of insufficient input validation, an overly long computer name can be used to overflow the "computer name" kernel stack buffer. This results in memory corruption which can be turned into arbitrary remote code execution.
Furthermore, a more detailed summary of this advisory has been published at our blog: http://blog.sec-consult.com
Proof of concept:
Below is an excerpt from the vulnerable run_init_sbus() function (pseudo code):
int computername_len; char computername_buf[64]; // connection initiation, handshake len = ks_recv(sock, &computername_len, 4, 0); // ... len = ks_recv(sock, computername_buf, computername_len, 0); // boom!
A proof of concept "netusb_bof.py" has been developed which exploits the vulnerability. The PoC DoS exploit will not be published as many vendors did not patch the vulnerability yet.
Example use that results in denial-of-service (kernel memory corruption that results in a device reboot): ./netusb_bof.py 192.168.1.1 20005 500

Solution:
TP-LINK has started releasing fixed firmware. The status of affected products can be found in the affected product list above.
For additional information also see CERT/CC vulnerability notice: http://www.kb.cert.org/vuls/id/177092
Workaround:
Sometimes NetUSB can be disabled via the web interface, but at least on NETGEAR devices this does not mitigate the vulnerability. NETGEAR told us, that there is no workaround available, the TCP port can't be firewalled nor is there a way to disable the service on their devices. It ensures the continued knowledge gain of SEC Consult in the field of network and application security to stay ahead of the attacker. The SEC Consult Vulnerability Lab supports high-quality penetration testing and the evaluation of new offensive and defensive technologies for our customers.

"data": "Stack-based buffer overflow in the run_init_sbus function in the KCodes NetUSB module for the Linux kernel, as used in certain NETGEAR products, TP-LINK products, and other products, allows remote attackers to execute arbitrary code by providing a long computer name in a session on TCP port 20005. KCodes NetUSB is vulnerable to a buffer overflow via the network that may result in a denial of service or code execution. KCodes NetUSB The kernel driver contains a buffer overflow vulnerability. KCodes NetUSB Is Linux Connected to base embedded devices (home router products, etc.) USB Share devices on the network \"USB over IP\" To realize the function, Linux Kernel module. Buffer overflow (CWE-120) - CVE-2015-3036 http://cwe.mitre.org/data/definitions/120.html The client NetUSB The data to send when connecting to the server NetUSB A buffer overflow can occur because the kernel driver does not validate properly.

Depending on the default settings of the device, a remote attack may be possible. KCodes NetUSB is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. \nAn attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts may result in a denial-of-service condition.

This results in\nmemory corruption which can be turned into arbitrary remote code execution. \n\nFurthermore, a more detailed summary of this advisory has been published at our\nblog: http://blog.sec-consult.com\n\n\nProof of concept:\n-----------------\nBelow is an excerpt from the vulnerable run_init_sbus() function (pseudo code):\n\nint computername_len;\nchar computername_buf[64];\n// connection initiation, handshake\nlen = ks_recv(sock, \u0026computername_len, 4, 0);\n// ... \nlen = ks_recv(sock, computername_buf, computername_len, 0); // boom!\n\nA proof of concept \"netusb_bof.py\" has been developed which exploits the\nvulnerability. The PoC DoS exploit will not be published as many vendors\ndid not patch the vulnerability yet. \n\nExample use that results in denial-of-service (kernel memory corruption that\nresults in a device reboot):\n./netusb_bof.py 192.168.1.1 20005 500\n\n\nVulnerable / tested versions:\n-----------------------------\nThe vulnerability has been verified to exist in most recent firmware versions\nof the following devives:\n\nTP-Link TL-WDR4300 V1\nTP-Link WR1043ND v2\nNETGEAR WNDR4500\n\nFurthermore we\u0027ve identified NetUSB in the most recent firmware version of the\nfollowing products (list is not necessarily complete!):\nD-Link DIR-615 C\nNETGEAR AC1450\nNETGEAR CENTRIA (WNDR4700/4720)\nNETGEAR D6100\nNETGEAR D6200\nNETGEAR D6300\nNETGEAR D6400\nNETGEAR DC112A\nNETGEAR DC112A (Zain)\nNETGEAR DGND4000\nNETGEAR EX6200\nNETGEAR EX7000\nNETGEAR JNR3000\nNETGEAR JNR3210\nNETGEAR JR6150\nNETGEAR LG6100D\nNETGEAR PR2000\nNETGEAR R6050\nNETGEAR R6100\nNETGEAR R6200\nNETGEAR R6200v2\nNETGEAR R6220\nNETGEAR R6250\nNETGEAR R6300v1\nNETGEAR R6300v2\nNETGEAR R6700\nNETGEAR R7000\nNETGEAR R7500\nNETGEAR R7900\nNETGEAR R8000\nNETGEAR WN3500RP\nNETGEAR WNDR3700v5\nNETGEAR WNDR4300\nNETGEAR WNDR4300v2\nNETGEAR WNDR4500\nNETGEAR WNDR4500v2\nNETGEAR WNDR4500v3\nNETGEAR XAU2511\nNETGEAR XAUB2511\nTP-LINK Archer C2 V1.0 (Fix planned before 2015/05/22)\nTP-LINK Archer C20 V1.0 (Not affected)\nTP-LINK Archer C20i V1.0 (Fix planned before 2015/05/25)\nTP-LINK Archer C5 V1.2 (Fix planned before 2015/05/22)\nTP-LINK Archer C5 V2.0 (Fix planned before 2015/05/30)\nTP-LINK Archer C7 V1.0 (Fix planned before 2015/05/30)\nTP-LINK Archer C7 V2.0 (Fix already released)\nTP-LINK Archer C8 V1.0 (Fix planned before 2015/05/30)\nTP-LINK Archer C9 V1.0 (Fix planned before 2015/05/22)\nTP-LINK Archer D2 V1.0 (Fix planned before 2015/05/22)\nTP-LINK Archer D5 V1.0 (Fix planned before 2015/05/25)\nTP-LINK Archer D7 V1.0 (Fix planned before 2015/05/25)\nTP-LINK Archer D7B V1.0 (Fix planned before 2015/05/31)\nTP-LINK Archer D9 V1.0 (Fix planned before 2015/05/25)\nTP-LINK Archer VR200v V1.0 (Fix already released)\nTP-LINK TD-VG3511 V1.0 (End-Of-Life)\nTP-LINK TD-VG3631 V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-VG3631 V1.0 (Fix planned before 2015/05/31)\nTP-LINK TD-W1042ND V1.0 (End-Of-Life)\nTP-LINK TD-W1043ND V1.0 (End-Of-Life)\nTP-LINK TD-W8968 V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-W8968 V2.0 (Fix planned before 2015/05/30)\nTP-LINK TD-W8968 V3.0 (Fix planned before 2015/05/25)\nTP-LINK TD-W8970 V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-W8970 V3.0 (Fix already released)\nTP-LINK TD-W8970B V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-W8980 V3.0 (Fix planned before 2015/05/25)\nTP-LINK TD-W8980B V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-W9980 V1.0 (Fix already released)\nTP-LINK TD-W9980B V1.0 (Fix planned before 2015/05/30)\nTP-LINK TD-WDR4900 V1.0 (End-Of-Life)\nTP-LINK TL-WR1043ND V2.0 (Fix planned before 2015/05/30)\nTP-LINK TL-WR1043ND V3.0 (Fix planned before 2015/05/30)\nTP-LINK TL-WR1045ND V2.0 (Fix planned before 2015/05/30)\nTP-LINK TL-WR3500 V1.0 (Fix planned before 2015/05/22)\nTP-LINK TL-WR3600 V1.0 (Fix planned before 2015/05/22)\nTP-LINK TL-WR4300 V1.0 (Fix planned before 2015/05/22)\nTP-LINK TL-WR842ND V2.0 (Fix planned before 2015/05/30)\nTP-LINK TL-WR842ND V1.0 (End-Of-Life)\nTP-LINK TX-VG1530(GPON) V1.0 (Fix planned before 2015/05/31)\nTrendnet TE100-MFP1 (v1.0R)\nTrendnet TEW-632BRP (A1.0R)\nTrendnet TEW-632BRP (A1.1R/A1.2R)\nTrendnet TEW-632BRP (A1.1R/A1.2R/A1.3R)\nTrendnet TEW-634GRU (v1.0R)\nTrendnet TEW-652BRP (V1.0R)\nTrendnet TEW-673GRU (v1.0R)\nTrendnet TEW-811DRU (v1.0R)\nTrendnet TEW-812DRU (v1.0R)\nTrendnet TEW-812DRU (v2.xR)\nTrendnet TEW-813DRU (v1.0R)\nTrendnet TEW-818DRU (v1.0R)\nTrendnet TEW-823DRU (v1.0R)\nTrendnet TEW-MFP1 (v1.0R)\nZyxel NBG-419N v2\nZyxel NBG4615 v2\nZyxel NBG5615\nZyxel NBG5715\n\nBased on information embedded in KCodes drivers we believe the following\nvendors are affected:\nAllnet\nAmbir Technology\nAMIT\nAsante\nAtlantis\nCorega\nDigitus\nD-Link\nEDIMAX\nEncore Electronics\nEngenius\nEtop\nHardlink\nHawking\nIOGEAR\nLevelOne\nLongshine\nNETGEAR\nPCI\nPROLiNK\nSitecom\nTaifa\nTP-LINK\nTRENDnet\nWestern Digital\nZyXEL\n\n\nVendor contact timeline:\n------------------------\n2015-02-28: Contacting vendor through support@kcodes.com\n2015-03-04: No response, contacting various KCodes addresses found on the web. \n2015-03-05: Vendor responds, requests more information. \n2015-03-05: Providing advisory and proof of concept exploit. \n2015-03-16: No response, requesting status update. \n2015-03-16: Vendor responds, asks about fix verification(?)\n2015-03-16: Requesting clarification about fixing status and information about\n next steps. Proposing conference call dates. \n2015-03-19: No response, informing that notification of CERT/CC and selected\n vendors will start shortly. Requesting clarification about fixing\n status and information about next steps again. \n2015-03-19: Vendor responds, confirms conference call date (2015-03-25). No\n further information provided. \n2015-03-19: Providing advisory and proof of concept exploit to TP-LINK and\n NETGEAR. \n2015-03-25: Vendor cancels conference call on short notice (sudden week-long\n business trip). \n2015-03-26: Asking for support of CERT/CC regarding vendor coordination. \n2015-03 - 2015-05: Coordination between CERT \u0026 vendors, NETGEAR and TP-LINK\n2015-05-13: Notifying German CERT-Bund and Austrian CERT.at\n2015-05-19: Coordinated release of security advisory\n\n\nSolution:\n---------\nTP-LINK has started releasing fixed firmware. The status of affected products\ncan be found in the affected product list above. \n\nFor additional information also see CERT/CC vulnerability notice:\nhttp://www.kb.cert.org/vuls/id/177092\n\n\nWorkaround:\n-----------\nSometimes NetUSB can be disabled via the web interface, but at least on NETGEAR\ndevices this does not mitigate the vulnerability. NETGEAR told us, that there is\nno workaround available, the TCP port can\u0027t be firewalled nor is there a way to\ndisable the service on their devices. It\nensures the continued knowledge gain of SEC Consult in the field of network\nand application security to stay ahead of the attacker. The SEC Consult\nVulnerability Lab supports high-quality penetration testing and the evaluation\nof new offensive and defensive technologies for our customers.

Vulnerability from variot
TRENDnet TEW-812DRU router allows remote authenticated users to execute arbitrary commands via shell metacharacters in the (1) wan network prefix to internet/ipv6.asp; (2) remote port to adm/management.asp; (3) pptp username, (4) pptp password, (5) ip, (6) gateway, (7) l2tp username, or (8) l2tp password to internet/wan.asp; (9) NtpDstStart, (10) NtpDstEnd, or (11) NtpDstOffset to adm/time.asp; or (12) device url to adm/management.asp. NOTE: vectors 9, 10, and 11 can be exploited by unauthenticated remote attackers by leveraging CVE-2013-3098. The Trendnet TEW-812DRU is a dual-band Gigabit router device. Trendnet TEW-812DRU multiple scripts incorrectly filter user-submitted input, allowing remote attackers to exploit malicious exploits to submit malicious requests to inject OS commands and execute them with WEB privileges. Trendnet TEW-812DRU is prone to multiple command-injection vulnerabilities. Exploiting these issues could allow an attacker to execute arbitrary commands in the context of the affected devices. There is a security vulnerability in TRENDnet TEW-812DRU router, the vulnerability is caused by the program not sufficiently filtering the 'NtpDstEnd' and '\'\'NtpDstOffset' fields in the setNTP.cgi script

NOTE: vectors 9, 10, and 11 can be exploited by unauthenticated remote attackers by leveraging CVE-2013-3098. The Trendnet TEW-812DRU is a dual-band Gigabit router device. Trendnet TEW-812DRU multiple scripts incorrectly filter user-submitted input, allowing remote attackers to exploit malicious exploits to submit malicious requests to inject OS commands and execute them with WEB privileges. Trendnet TEW-812DRU is prone to multiple command-injection vulnerabilities. \nExploiting these issues could allow an attacker to execute arbitrary commands in the context of the affected devices. There is a security vulnerability in TRENDnet TEW-812DRU router, the vulnerability is caused by the program not sufficiently filtering the \u0027NtpDstEnd\u0027 and \u0027\\\u0027\\\u0027NtpDstOffset\u0027 fields in the setNTP.cgi script",
