CyberRota Analysis
AI-GeneratedThe Issabel Framework, utilized by Issabel PBX software, contains a critical vulnerability due to a hard-coded HS256 JWT signing key in the pbxapi index.php file, which is identical across all installations. This flaw allows unauthenticated remote attackers to forge valid bearer tokens, enabling them to execute arbitrary OS commands as the Asterisk user through the manager originate endpoint. Organizations using Issabel PBX should prioritize immediate remediation to mitigate the risk of unauthorized access and potential system compromise.

Original NVD Description
The Issabel Framework, the web framework supporting Issabel PBX software, before commit b97dbaf contains a hard-coded HS256 JWT signing key in the pbxapi index.php file that is identical across every installation, allowing unauthenticated remote attackers to forge valid bearer tokens. Attackers can use the forged token to call the manager originate endpoint with the System application parameter, causing Asterisk to execute arbitrary OS commands as the Asterisk user. Exploitation evidence was first observed by the Shadowserver Foundation on 2026-09-09.
