Name of the Vulnerable Software and Affected Versions: a-blog cms versions prior to 3.1.43 a-blog cms versions prior to 3.0.47

Description: The issue is related to insufficient path validation in the backup feature of a-blog cms, which can be exploited by a remote authenticated attacker with administrator privilege to obtain or delete any file on the server. This requires the attacker to have administrator privileges.

Recommendations: For versions prior to 3.1.43, update to version 3.1.43 or later. For versions prior to 3.0.47, update to version 3.0.47 or later. As a temporary workaround, consider restricting access to the backup feature until a patch is available.
