Description

A stack-based buffer overflow exists in the get_merge_mac function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to six user-supplied CGI parameters matching <parameter>_0~5 into a fixed-size buffer (a2) without proper bounds checking, appending colon delimiters during concatenation. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.

Attack-Flow Graph

Executive Summary

This vulnerability is a stack-based buffer overflow in the get_merge_mac function of the httpd binary on Linksys E1200 v2 routers. The function concatenates up to six user-supplied CGI parameters into a fixed-size buffer without proper bounds checking, allowing remote attackers to exploit specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.

Impact Analysis

An attacker can exploit this vulnerability remotely without authentication to execute arbitrary code on the affected router or cause a denial of service, potentially disrupting network availability or compromising the device.
