WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in confirmLivePassword.php that copies REQUEST_URI into a form action attribute without encoding. Attackers can craft a malicious URL with a quote character to break out of the action attribute and inject event handlers that execute in the victim's browser within the site origin.
AnalysisAI
Reflected XSS in WWBN AVideo's confirmLivePassword.php allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser by tricking them into visiting a crafted URL. The vulnerability arises because the PHP script copies REQUEST_URI verbatim into an HTML form action attribute - a quote character in the URL path breaks attribute context and enables injection of arbitrary event handlers executing within the site's origin. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim click or be redirected to a specifically crafted URL targeting the confirmLivePassword.php endpoint on an AVideo instance accessible over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector scores this at 5.3 (Medium), capturing the core trade-off: zero authentication or special configuration required (PR:N, AC:L), but victim interaction is mandatory (UI:P), and the confidentiality and integrity impacts are limited (VC:L/VI:L). … 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 | The primary fix is to upgrade AVideo to a commit beyond c3edcc274c389816d434acadac07ee78eaf330c1 that addresses the REQUEST_URI encoding issue - consult the GitHub advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-fp9p-hrc9-8rr7 for the exact remediated commit or release. … Detailed patch versions, workarounds, and compensating controls in full report. |
