By using this buffer overflow, a remote attacker can start the telnetd service. This service has a hardcoded default username and password (root/123456). Although it has a restrictive shell, this can be easily bypassed via the built-in ECHO shell command."}], "lastModified": "2024-11-21T06:31:50.680", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:uniview:camera_firmware:-:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5193EE14-B4B7-4708-BD58-F0DD2DB0F0CD"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
