CVE-2025-60690

A stack-based buffer overflow exists in the get_merge_ipaddr function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to four user-supplied CGI parameters matching <parameter>_0~3 into a fixed-size buffer (a2) without bounds checking. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.
