Technical Analysis

This vulnerability affects DedeCMS up to and including version 5.7.118. The flaw exists in an unspecified function within the plus/mytag_js.php file, where the 'aid' parameter can be manipulated to perform code injection remotely. The vulnerability is remotely exploitable without authentication or user interaction, with low complexity and low vector and impact metrics as per CVSS 4.0. Public exploit code has been released, increasing the risk of exploitation.

Potential Impact

Successful exploitation allows an attacker to inject arbitrary code remotely, potentially leading to unauthorized code execution within the affected DedeCMS instance. This can compromise the integrity and confidentiality of the system and data. However, no confirmed active exploitation in the wild has been reported.
