Published: 22 August 2022
Summary
CVE-2022-32772 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Wwbn Avideo. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 7.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A cross-site scripting vulnerability exists in the footer alerts functionality of WWBN AVideo version 11.6 and the development master commit 3f7c0364. The issue stems from insufficient sanitization of the "msg" parameter, which is inserted directly into the document and permits arbitrary JavaScript execution when a crafted value is supplied.
An unauthenticated attacker can exploit the flaw by crafting an HTTP request that is then sent by an authenticated user, resulting in JavaScript execution in the victim's browser context with a CVSS score of 6.1 under CWE-79.
Public references point to the Talos Intelligence report TALOS-2022-1538 and the AVideo updateDb.v12.0.sql database migration script as sources for remediation details.
EPSS for the vulnerability reached a peak of 0.1115 before receding to the current value of 0.0780.
