Unknown Unknown - Not Provided
BaseFortify

Publication date: 2025-11-13

Last updated on: 2025-11-17

Assigner: MITRE

Description
A stack-based buffer overflow exists in the httpd binary of Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The apply_cgi and block_cgi functions copy user-supplied input from the "url" CGI parameter into stack buffers (v36, v29) using sprintf without bounds checking. Because these buffers are allocated as single-byte variables, any non-empty input will trigger a buffer overflow. Remote attackers can exploit this vulnerability via crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack-based buffer overflow in the httpd binary of Linksys E1200 v2 routers. It occurs because the apply_cgi and block_cgi functions copy user-supplied input from the "url" CGI parameter into stack buffers using sprintf without checking the input size. Since the buffers are very small, any non-empty input causes the buffer to overflow, allowing remote attackers to exploit this flaw by sending crafted HTTP requests to execute arbitrary code or cause denial of service without needing authentication.


How can this vulnerability impact me? :

This vulnerability can allow remote attackers to execute arbitrary code on the affected router or cause a denial of service. This means attackers could take control of the device, disrupt its normal operation, or potentially use it as a foothold to attack other devices on the network, all without requiring any authentication.
