Descriptions

In certain EZVIZ products, two stack based buffer overflows in mulicast_parse_sadp_packet and mulicast_get_pack_type functions of the SADP multicast protocol can allow an unauthenticated attacker present on the same local network as the camera to achieve remote code execution. This affects CS-C6N-B0-1G2WF Firmware versions before V5.3.0 build 230215 and CS-C6N-R101-1G2WF Firmware versions before V5.3.0 build 230215 and CS-CV310-A0-1B2WFR Firmware versions before V5.3.0 build 230221 and CS-CV310-A0-1C2WFR-C Firmware versions before V5.3.2 build 230221 and CS-C6N-A0-1C2WFR-MUL Firmware versions before V5.3.2 build 230218 and CS-CV310-A0-3C2WFRL-1080p Firmware versions before V5.2.7 build 230302 and CS-CV310-A0-1C2WFR Wifi IP66 2.8mm 1080p Firmware versions before V5.3.2 build 230214 and CS-CV248-A0-32WMFR Firmware versions before V5.2.3 build 230217 and EZVIZ LC1C Firmware versions before V5.3.4 build 230214.

En determinados productos EZVIZ, dos desbordamientos de búfer basados en pila en las funciones mulicast_parse_sadp_packet y mulicast_get_pack_type del protocolo de multidifusión SADP pueden permitir a un atacante no autenticado presente en la misma red local que la cámara lograr la ejecución remota de código. Esto afecta a las versiones de firmware CS-C6N-B0-1G2WF anteriores a V5.3.0 build 230215 y a las versiones de firmware CS-C6N-R101-1G2WF anteriores a V5.3.0 build 230215 y a las versiones de firmware CS-CV310-A0-1B2WFR anteriores a V5.3.0 build 230221 y a las versiones de firmware CS-CV310-A0-1C2WFR-C anteriores a V5.3.2 build 230221 y a las versiones de firmware CS-C6N-A0-1C2WFR-MUL anteriores a V5.3.2 build 230218 y a las versiones de firmware CS-C6N-A0-1C2WFR-MUL anteriores a V5.3.2 build 230218 y a las versiones de firmware CS-CV310-A0-3C2WFRL-1080p anteriores a V5.2.7 build 230302 y a las versiones de firmware CS-CV310-A0-1C2WFR Wifi IP66 2.8mm 1080p anteriores a V5.3.2 build 230214 y a las versiones de firmware CS-CV248-A0-32WMFR anteriores a V5.2.3 build 230217 y a las versiones de firmware EZVIZ LC1C anteriores a V5.3.4 build 230214.
