Description

Renovate versions from 32.135.0 before 40.33.0 contain a command injection vulnerability in the hermit manager where user-provided dependency names are appended to install and uninstall commands without proper sanitization. Attackers with repository write access can provide maliciously named hermit dependencies to execute arbitrary commands on the machine running Renovate.

Executive Summary

This vulnerability is a command injection flaw in Renovate versions 32.135.0 to 40.33.0. It occurs in the Hermit manager where user-provided dependency names are added to install and uninstall commands without proper sanitization. Attackers with repository write access can exploit this by naming dependencies maliciously to execute arbitrary commands on the Renovate machine.

Detection Guidance

Check Renovate version with npm list -g renovate or grep renovate package.json. Inspect logs for hermit manager commands like ./hermit install or ./hermit uninstall. Look for malformed dependency names in Renovate configuration files.

Impact Analysis

If exploited, attackers could run arbitrary commands on the machine running Renovate, potentially leading to unauthorized access, data theft, system compromise, or service disruption. For example, an attacker could terminate critical processes like the root process in a Docker container running Renovate.

Compliance Impact

This vulnerability could lead to breaches of confidentiality, integrity, and availability of sensitive data, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Unauthorized command execution could expose personal or health data, leading to legal and regulatory penalties.

Mitigation Strategies

Upgrade Renovate to version 40.33.0 or later. Remove write access for untrusted users to repositories scanned by Renovate. Review and sanitize dependency names in configuration files.
