      "value": "A stack-based buffer overflow vulnerability exists in the libshared.so library of Cisco Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The functions get_mac_from_ip and get_ip_from_mac use sscanf with overly permissive \"%100s\" format specifiers to parse entries from /proc/net/arp into fixed-size buffers (v6: 50 bytes, v7 sub-arrays: 50 bytes). This allows local attackers controlling the contents of /proc/net/arp to overflow stack buffers, leading to memory corruption, denial of service, or potential arbitrary code execution."

Las funciones get_mac_from_ip y get_ip_from_mac utilizan sscanf con especificadores de formato “%100s” excesivamente permisivos para analizar entradas de /proc/net/arp en búferes de tamaño fijo (v6: 50 bytes, sub-arrays v7: 50 bytes). Esto permite a atacantes locales que controlan el contenido de /proc/net/arp desbordar los búferes de pila, lo que lleva a corrupción de memoria, denegación de servicio o una potencial ejecución de código arbitrario."
