CVE-2017-5539

Name of the Vulnerable Software and Affected Versions b2evolution version 6.8.4-stable

Description The issue allows an attacker to bypass a filter rule using ../, enabling them to delete or read any files on the server, as well as determine whether a file exists.

Recommendations For b2evolution version 6.8.4-stable, as a temporary workaround, consider restricting access to sensitive files and directories until a patch is available. Avoid using the ../ sequence in file paths to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
