Unauthenticated network injection (PR:N/AV:N/AC:L) but payload fires only when an admin views the report (UI:R); JS in admin session with scope change (S:C) yields high C/I, no availability impact.

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the AD_Server plugin's log.php endpoint that fails to escape the label parameter before storage. An unauthenticated attacker can inject malicious HTML through the label parameter, which is later rendered unsanitized in the admin Ad Types report using jQuery .html(), allowing execution of arbitrary JavaScript in an administrator's browser session.

AnalysisAI
Stored cross-site scripting in WWBN AVideo's AD_Server plugin lets an unauthenticated attacker persist malicious HTML via the unescaped 'label' parameter of the log.php endpoint, which later executes as arbitrary JavaScript when an administrator opens the Ad Types report. Because the admin report renders the stored value with jQuery .html() without sanitization, exploitation yields code execution in a privileged administrator's browser session, enabling account/session takeover of the affected AVideo installation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the AD_Server plugin to be enabled and its log.php endpoint reachable by the attacker; the injection itself needs no authentication (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 9.3 reflects a network vector, low complexity, no privileges required, and only passive/required user interaction (UI:P) - an administrator merely viewing the ad report triggers execution. … 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 | Upstream fix available (referenced via the vendor GitHub Security Advisory GHSA-h68w-3r38-wmm8); released patched version not independently confirmed from the provided data - update AVideo to the latest commit/release beyond c3edcc274c389816d434acadac07ee78eaf330c1 that follows the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify whether your WWBN AVideo installation has the AD_Server plugin enabled by reviewing plugin configuration; if present, disable it immediately unless critical to operations. …
