CVE-2022-47924

Code execution via unrestricted validation function invocation

Published Mar 27, 2023 · Updated Feb 19, 2025

Improper input validation in csaf-validator-lib before 0.1.0 allows local users with high privileges to execute code or interrupt validation. The validate function invokes a function supplied through its arguments without restricting it to the library's trusted predefined functions. Exploitation requires high local privileges and a user to trigger validation, after which attacker-controlled code runs or validation is interrupted.
