CVE-2023-34552 Detail

Modified After Enrichment

This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.

Description

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.
