DescriptionCVE.org

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in view/logArchive.json.php that allows unauthenticated attackers to archive application logs by making GET requests without CSRF token validation. Attackers can craft malicious pages that trigger administrators' browsers to request the endpoint, copying sensitive application logs to a publicly accessible zip file and truncating the live log to remove forensic evidence.

AnalysisAI

Cross-site request forgery in WWBN AVideo's log archive endpoint allows unauthenticated remote attackers to exfiltrate sensitive application logs and destroy forensic evidence by tricking an authenticated administrator into visiting a malicious page. The view/logArchive.json.php endpoint accepts GET requests without any CSRF token validation, so a crafted page silently causes the administrator's browser to trigger log archiving - copying live logs into a publicly accessible zip file while simultaneously truncating the original log to eliminate attack traces. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that a logged-in AVideo administrator with an active session visits an attacker-controlled web page or loads attacker-supplied content in their browser. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 7.1 reflects the combination of network reachability (AV:N), low complexity (AC:L), and high confidentiality impact (VC:H), tempered by the user-interaction prerequisite (UI:P - passive interaction, meaning the admin need only load a page). … 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 Upgrade WWBN AVideo to a commit beyond c3edcc274c389816d434acadac07ee78eaf330c1 once a patched release is published; monitor the GitHub Security Advisory GHSA-66vx-xf88-hpw8 (https://github.com/WWBN/AVideo/security/advisories/GHSA-66vx-xf88-hpw8) for a tagged fix version, as no specific patched release is confirmed in the available data at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, restrict network access to the /view/logArchive.json.php endpoint via firewall rules and alert all administrators to avoid clicking untrusted links while logged into AVideo. …
