CVE-2021-23154

Arbitrary command execution via concatenated Helm arguments

Published Jan 10, 2022 · Updated Aug 3, 2024

OS command injection in Mirantis Lens 5.3.3 and earlier allows context-dependent attackers to run shell commands through custom Helm configuration. The Helm release and repository managers concatenate supplied chart arguments into command strings passed to promiseExec, which invokes the user's shell instead of passing an argument array directly to the Helm executable. Exploitation requires a targeted user to enter attacker-provided configuration, after which commands execute with that user's operating-system privileges.
