Detailsinfo

A vulnerability, which was classified as critical, has been found in WWBN AVideo up to 29.0. This issue affects the function isSSRFSafeURL of the file objects/EpgParser.php. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. In versions up to and including 29.0, two endpoints (plugin/AI/receiveAsync.json.php and objects/EpgParser.php) in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections. Commit 603e7bf77a835584387327e35560262feb075db3 contains an updated fix.
