CVE-2025-60693

Full vulnerability record from the local CVENow database.

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.

La función concatena hasta seis parámetros CGI proporcionados por el usuario que coinciden con <parámetro>_0~5 en un búfer de tamaño fijo (a2) sin una comprobación de límites adecuada, añadiendo delimitadores de dos puntos durante la concatenación. Atacantes remotos pueden explotar esta vulnerabilidad mediante solicitudes HTTP especialmente diseñadas para ejecutar código arbitrario o causar denegación de servicio sin autenticación."
