Description

LDAP Account Manager (LAM) is a webfrontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. In versions prior to 8.0 incorrect regular expressions allow to upload PHP scripts to config/templates/pdf. This vulnerability could lead to a Remote Code Execution if the /config/templates/pdf/ directory is accessible for remote users. This is not a default configuration of LAM. This issue has been fixed in version 8.0. There are no known workarounds for this issue.

Affected products

• ldap-account-manager Ldap Account Manager: before 8.0 — fixed in 8.0

How to fix

Upgrade to a fixed version: ldap-account-manager Ldap Account Manager 8.0. Check the vendor advisory for mitigations.
