Name of the Vulnerable Software and Affected Versions LDAP Account Manager versions prior to 8.0

Description The issue allows an attacker to gain code execution on the host by writing a web-shell into the tmp directory, accessible via /lam/tmp/. This directory allows interpretation of .php files, and an attacker with www-data privileges can exploit this. The problem has been fixed in version 8.0.

Recommendations For versions prior to 8.0, disallow executing PHP scripts in the (/var/lib/ldap-account-manager/)tmp directory as a temporary workaround until the issue is resolved. As a permanent solution, upgrade to version 8.0 or later.
