Description

LDAP Account Manager (LAM) is a webfrontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. Prior to version 9.5, a local file inclusion was detected in the PDF export that allows users to include local PHP files and this way execute code. In combination with GHSA-88hf-2cjm-m9g8 this allows to execute arbitrary code. Users need to login to LAM to exploit this vulnerability. Version 9.5 fixes the issue. Although upgrading is recommended, a workaround would be to make /var/lib/ldap-account-manager/config read-only for the web-server user and delete the PDF profile files (making PDF exports impossible).

Analysis

LDAP Account Manager (LAM), a web-based interface for managing LDAP directory entries, contains a local file inclusion vulnerability in its PDF export functionality that allows authenticated users to include and execute arbitrary PHP files. When chained with GHSA-88hf-2cjm-m9g8, this vulnerability enables complete remote code execution on the affected server. …
