Vulnerability from variot - Updated: 2023-12-18 12:56

TRENDnet TEW-673GRU v1.00b40 devices have an OS command injection vulnerability in the start_arpping function of the timer binary, which allows remote attackers to execute arbitrary commands via three parameters (dhcpd_start, dhcpd_end, and lan_ipaddr) passed to the apply.cgi binary through a POST request. TRENDnet TEW-673GRU The device includes OS A command injection vulnerability exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The TRENDnetTEW-673GRU is a dual-band green router. There is a command injection vulnerability in TRENDnetTEW-673GRU. ########################################### Vulnerabilities found in TRENDnet devices

Authors:Prashast Srivastava, Mathias Payer Howard Shrobe, Hamed Okhravi

Author contact: https://github.com/prashast/

Multiple vulnerabilties including Command Injection, Buffer Overflow and Reflective XSS vulnerabilties were found in the following TRENDnet devices: Routers: TEW-634GRU, TEW-673GRU, TEW-632BRP IP-Cameras: TV-IP110WN, TV-IP121WN These were found using our dynamic analysis tool for embedded devices. The POC's will be made available upon the public release of our tool. Exploiting the vulnerability requires a user to be authenticated with the router with administrative credentials.

The start_arpping function reads the following values from the NVRAM namely: dhcpd_start, dhcpd_end, lan_ipaddr, lan_bridge and lan_eth. These values are then passed to the arpping utility without any sort of sanity checks. Out of these values, the outward facing configuration webserver(httpd) running at IP:192.168.10.1 Port: 80 allows a user to modify the first three values dhcpd_start, dhcpd_end, lan_ipaddr via the LAN and DHCP server configuration webpage available at http://192.168.10.1/lan.asp by making a POST request to apply.cgi binary with the appropriate parameters.

Buffer Overflows

CVE-ID: CVE-2018-19240 Products: - TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64) - TV-IP121WN (V1.2.2 build 28) Module affected: network.cgi

Buffer overflow can be exploited by using the iptype parameter in network.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication)

CVE-ID: CVE-2018-19241 Products: - TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64) - TV-IP121WN (V1.2.2 build 28) Module affected: video.cgi

A BoF vulnerability exists in the CGI binary which can modify the quality of the video recorded on the camera. A sub-routine respondAsp is called that copies a user-controlled parameter into a stack variable using strcpy without any bounds check. This makes the subroutine vulnerable to BoF and can be exploited without authentication

Products: - TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64) - TV-IP121WN (V1.2.2 build 28) Module affected: watch.cgi

A BoF vulnerability exists in the watch.cgi binary and how it handles the url parameter. An attacker can deliver its payload using a POST request in the url parameter to trigger the BoF vulnerability without authentication.

x-----------x

CVE-ID: CVE-2018-19242 Products: - TEW-632BRP (1.010B32) - TEW-673GRU (v1.00b40) Module affected: apply.cgi

Buffer overflow in apply.cgi on TRENDnet TEW-632BRP 1.010B32 and TEW-673GRU devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload(with authentication).

Reflective XSS

Products: - TEW-632BRP (1.010B32) - TEW-673GRU (v1.00b40) - TEW-634GRU (v1.01B14)

Module affected: login.cgi

Login.cgi in TRENDNet TEW-632BRP, TEW-673GRU and TEW-634GRU has a reflected XSS vulnerability that does not require any authentication.

Vendor Disclosure

The vulnerabilities had been notified to the vendor 12/03. The vendor replied on 12/05 that since the products had reached their end-of-life no future development or firmware updates would be provided for these devices

There is a command injection vulnerability in TRENDnetTEW-673GRU. ###########################################\nVulnerabilities found in TRENDnet devices\n\nAuthors:Prashast Srivastava, Mathias Payer\n        Howard Shrobe, Hamed Okhravi\n\nAuthor contact: https://github.com/prashast/\n\n###########################################\n\nMultiple vulnerabilties including Command Injection, Buffer Overflow and\nReflective XSS vulnerabilties were found in the following TRENDnet devices:\nRouters: TEW-634GRU, TEW-673GRU, TEW-632BRP\nIP-Cameras: TV-IP110WN, TV-IP121WN\nThese were found using our dynamic analysis tool for embedded devices. \nThe POC\u0027s will be made available upon the public\nrelease of our tool. Exploiting the\nvulnerability\nrequires a user to be authenticated with the router with\nadministrative credentials. \n\nThe `start_arpping` function reads the following values from the NVRAM\nnamely: dhcpd_start,\ndhcpd_end, lan_ipaddr, lan_bridge and lan_eth. These values are then\npassed to the\n`arpping` utility without any sort of sanity checks. \nOut of these values, the outward facing configuration webserver(httpd)\nrunning at\n`IP:192.168.10.1 Port: 80` allows a user to modify the first three\nvalues `dhcpd_start`,\n`dhcpd_end`, `lan_ipaddr` via the LAN and DHCP server configuration\nwebpage available at\n`http://192.168.10.1/lan.asp` by making a POST request to `apply.cgi`\nbinary with the\nappropriate parameters. \n\nBuffer Overflows\n------------------\n\nCVE-ID: CVE-2018-19240\nProducts:\n- TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64)\n- TV-IP121WN (V1.2.2 build 28)\nModule affected: `network.cgi`\n\nBuffer overflow can be exploited by using the `iptype` parameter\nin network.cgi on TRENDnet TV-IP110WN V1.2.2 build 68,\nV1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows\nattackers to hijack the control flow to any attacker-specified location by\ncrafting a POST request payload (without authentication)\n\nx-----------x\n\nCVE-ID: CVE-2018-19241\nProducts:\n- TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64)\n- TV-IP121WN (V1.2.2 build 28)\nModule affected: `video.cgi`\n\nA BoF vulnerability exists in the CGI binary which can modify the quality of\nthe video recorded on the camera. A sub-routine respondAsp is called that\ncopies a user-controlled parameter into a stack variable using strcpy\nwithout any\nbounds check. This makes the subroutine vulnerable to BoF and can be exploited\nwithout authentication\n\nx-----------x\n\nProducts:\n- TV-IP110WN (V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64)\n- TV-IP121WN (V1.2.2 build 28)\nModule affected: `watch.cgi`\n\nA BoF vulnerability exists in the `watch.cgi` binary and how it handles\nthe `url` parameter. An attacker can deliver its payload using a POST request\nin the `url` parameter to trigger the BoF vulnerability without authentication. \n\nx-----------x\n\nCVE-ID: CVE-2018-19242\nProducts:\n- TEW-632BRP (1.010B32)\n- TEW-673GRU (v1.00b40)\nModule affected: `apply.cgi`\n\n\nBuffer overflow in apply.cgi on TRENDnet TEW-632BRP 1.010B32 and TEW-673GRU\ndevices allows attackers to hijack the control flow to any attacker-specified\nlocation by crafting a POST request payload(with authentication). \n\n\nReflective XSS\n---------------\n\nProducts:\n- TEW-632BRP (1.010B32)\n- TEW-673GRU (v1.00b40)\n- TEW-634GRU (v1.01B14)\n\nModule affected: `login.cgi`\n\n`Login.cgi` in TRENDNet TEW-632BRP, TEW-673GRU and TEW-634GRU has a\nreflected XSS\nvulnerability that does not require any authentication. \n\nVendor Disclosure\n------------------\n\nThe vulnerabilities had been notified to the vendor 12/03. \nThe vendor replied on 12/05 that since the products had reached their\nend-of-life no future development or firmware updates\nwould be  provided for these devices",

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
