Deeper analysis

AVideo is an open source video platform that contained an OS command injection vulnerability, tracked as CVE-2023-30854, in the authenticated endpoint /plugin/CloneSite/cloneClient.json.php prior to version 12.4. The flaw, assigned CWE-78, permitted remote code execution and received a CVSS 3.1 score of 8.8 reflecting network-accessible exploitation with low attack complexity and low privileges required.

An authenticated attacker could supply crafted input to the vulnerable endpoint and execute arbitrary operating system commands on the server, achieving full remote code execution with the privileges of the web application process. No user interaction or special network positioning was needed beyond valid credentials.

The GitHub Security Advisory GHSA-6vrj-ph27-qfp3 states that the issue is resolved in AVideo 12.4; administrators should upgrade to that release to eliminate the injection vector.

EPSS for the CVE rose from a low baseline to a peak of 0.7021 on 2026-03-04 before receding to the current value of 0.3223, indicating a clear post-disclosure increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
