CVE-2020-37267: Renovate 19.180.0 before 23.25.1 Token Leakage via Logs

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.43% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: renovatebot renovate 23.25.1.

Low priority for now. Upgrade to renovatebot renovate 23.25.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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 because the git http.extraheader=AUTHORIZATION parameter is logged without redaction. Anyone with access to saved logs could obtain the bot credentials. Fixed in 23.25.1; Azure DevOps users should revoke and regenerate credentials if logs may have been exposed.
