A weakness has been identified in light0011 cms c774dce31c6df0055568a8d5c53d964d99be199d/f72cf46f601efb2a0618c3814cc2f61380b38930. This vulnerability affects the function catchimage of the file Public/ueditor/php/controller.php of the component UEditor. This manipulation of the argument source[] causes server-side request forgery. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Server-side request forgery in light0011 CMS allows unauthenticated remote attackers to force the server to fetch arbitrary URLs by manipulating the source[] parameter in the bundled UEditor catchimage function at Public/ueditor/php/controller.php. Successful exploitation enables internal network reconnaissance, access to cloud metadata services (e.g., AWS IMDSv1), and pivoting to other HTTP endpoints not exposed externally. …
