Vulnerability AssessmentAI

Exploitation Exploitation targets the Network Configuration Management component of the Tenda CP3 (firmware 27.5.57.101) and, per the CVSS 4.0 vector's PR:H, requires authenticated high-privilege (administrator) access to the camera's management interface reachable over the network; input reaching sub_2F77E8 in Apis/system.c must be attacker-controllable. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely high-impact bug (full device RCE) but several signals temper the raw 9.4 score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch identified at time of analysis; the references contain only VulDB entries and Tenda's homepage, not a fixed firmware version. … Detailed patch versions, workarounds, and compensating controls in full report.
