CVE-2022-43758Network attack vector

Code execution via ambiguous Git arguments

Published Feb 7, 2023 · Updated Mar 25, 2025

OS command injection in the Git package in Rancher allows remote authenticated users to execute code through crafted repository URLs. The package passes attacker-controlled Git input to the Git binary without disambiguating option-like values, so crafted catalog or KDM URLs alter the invoked command. By default, only administrators can add untrusted Helm catalogs or change the KDM download URL, and successful exploitation runs code in the Rancher host context.
