CVE-2020-37267 renovatebot CVE debrief

Who should care

Azure DevOps users who utilize Renovate bot for dependency management should assess exposure and prioritize credential revocation if logs may have been exposed. This includes reviewing Azure DevOps logs for potential Renovate bot authorization token exposure, revoking and regenerating credentials as necessary, and verifying log storage and access controls. Immediate attention is required to mitigate potential unauthorized access to Renovate bot credentials

Why it matters

CVE-2020-37267 exposes Renovate bot authorization tokens in Azure DevOps logs, requiring immediate attention from DevOps teams to assess exposure, revoke and regenerate credentials, and verify log storage and access controls.

• Potential unauthorized access to Renovate bot credentials
• Possible lateral movement within Azure DevOps environments
• Required verification of log storage and access controls
• Need for credential revocation and regeneration

Technical summary

Renovate versions >=19.180.0 and <23.25.1, when used with Azure DevOps, may expose the bot's authorization token in server or pipeline logs due to the git http.extraheader=AUTHORIZATION parameter being logged without redaction. This exposure can lead to unauthorized access to Renovate bot credentials, allowing potential lateral movement within Azure DevOps environments. Users should assess exposure, prioritize credential revocation, and verify log storage and access controls. The issue is fixed in version 23.25.1, and Azure DevOps users should revoke and regenerate credentials if logs may have been exposed.

Defensive priority

Azure DevOps users should assess exposure, prioritize credential revocation

Recommended defensive actions

• Assess exposure: Review Azure DevOps logs for potential Renovate bot authorization token exposure.
• Revoke and regenerate credentials: If logs may have been exposed, revoke and regenerate Renovate bot credentials.
• Verify log storage and access controls: Ensure proper storage and access controls are in place for Azure DevOps logs.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
