AI-suggested
- Upgrade LDAP Account Manager to version 9.5 or later, which contains the official fix for this vulnerability.
- Until upgrading is possible, restrict the web server user's permissions by making the /var/lib/ldap-account-manager/config directory read-only to prevent modification or inclusion of malicious files.
- Delete or disable PDF profile files to prevent use of the vulnerable PDF export feature, effectively blocking the attack vector.
- Implement strict access controls and monitoring on the LAM application to detect unauthorized login attempts and suspicious activities.
- Limit LAM access to trusted networks or VPNs to reduce exposure to potential attackers.
- Regularly audit and review user accounts with access to LAM to minimize the number of privileged users.
- Employ web application firewalls (WAF) with rules to detect and block local file inclusion attempts targeting LAM.
- Monitor logs for unusual PHP file inclusions or errors related to PDF exports to identify exploitation attempts early.
Description
CVE-2026-27894 is a high-severity vulnerability in LDAP Account Manager (LAM) versions prior to 9.5 that allows authenticated users to perform local file inclusion via the PDF export functionality. This flaw stems from improper control of filenames used in PHP include/require statements, enabling attackers to execute arbitrary PHP code on the server. Exploitation requires user login but no additional user interaction. The vulnerability can be combined with another (GHSA-88hf-2cjm-m9g8) to escalate impact. The issue is fixed in LAM version 9.5. As a workaround, administrators can restrict write permissions on the configuration directory and remove PDF profile files to disable PDF exports. The CVSS score is 8.8, reflecting high impact on confidentiality, integrity, and availability with network attack vector and low complexity.
