Detailsinfo

A vulnerability was found in EZVIZ CS-C6N-B0-1G2WF, CS-C6N-R101-1G2WF, CS-CV310-A0-1B2WFR, CS-CV310-A0-1C2WFR-C, CS-C6N-A0-1C2WFR-MUL, CS-CV310-A0-3C2WFRL-1080p, CS-CV310-A0-1C2WFR, CS-CV248-A0-32WMFR and LC1C. It has been declared as critical. Affected by this vulnerability is the function netClientSetWlanCfg of the component SDK Command Server. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In certain EZVIZ products, two stack buffer overflows in netClientSetWlanCfg function of the EZVIZ SDK command server can allow an authenticated 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.
