Vulnerability from variot
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). TRENDnet TEW-632BRP and TEW-673GRU The device contains a buffer error vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. TRENDnetTEW-632BRP is a router. The TRENDnetTEW-673GRU is a dual-band green router. A buffer overflow vulnerability exists in TRENDnetTEW-632BRP and TEW-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. A more detailed breakdown is presented below on a per vulnerability basis:-
Command Injection
CVE-ID: CVE-2018-19239
Product: TEW-673GRU
Module affected: start_arpping function in timer binary
Firmware version: v1.00b40
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. 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.
We have observed that the by directly making a POST request to the
apply.cgi binary
with the values of the above mentioned three parameters containing
Command Injection
based payloads, it is possible to execute arbitrary commands on the
router with root
privileges. 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
x-----------x
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.
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
