CVE-2022-31086Network attack vector

Authenticated code execution via PDF-template upload regex

Published Jun 27, 2022 · Updated Apr 23, 2025

Remote code execution in LDAP Account Manager before 8.0 allows remote authenticated users to upload executable PHP via the PDF-template editor. The PDF-template upload validator applies incorrect regular expressions to attacker-controlled filenames, allowing PHP scripts into config/templates/pdf. Execution requires the normally private config/templates/pdf directory to be web-accessible, which is not the default configuration.
