CVE-2022-31087 (GCVE-0-2022-31087)

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

Title

Incorrect Default Permissions 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 the tmp directory, which is accessible by /lam/tmp/, allows interpretation of .php (and .php5/.php4/.phpt/etc) files. An attacker capable of writing files under www-data privileges can write a web-shell into this directory, and gain a Code Execution on the host. This issue has been fixed in version 8.0. Users unable to upgrade should disallow executing PHP scripts in (/var/lib/ldap-account-manager/)tmp directory.
