CVE-2022-31086 (GCVE-0-2022-31086)

Vulnerability from cvelistv5 – Published: 2022-06-27 20:50 – Updated: 2025-04-23 18:07

Title

Incorrect Regular Expressions in ldap-account-manager

Summary

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.
