CVE-2022-48422Public exploit

Privilege escalation via current-directory library loading

Published Mar 19, 2023 · Updated Feb 27, 2025

Uncontrolled library search in ONLYOFFICE Docs 7.3 and earlier allows local users to gain privileges when a document is opened on Linux. The Linux desktop editor searches the document's current working directory for libgcc_s.so.1 before system library paths and loads an attacker-placed library. Exploitation requires a user to open a document from an attacker-writable directory, causing code to run with that user's privileges.
