MediumCVSS 5.3 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.33% (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.
  • According to the record, no fixed version is available yet.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

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

A flaw was found in the Ansible Automation Platform automation-controller. The unauthenticated Bitbucket Data Center webhook receiver skips HMAC signature verification for diagnostics:ping events after it has already looked up the target template, causing the endpoint to return HTTP 200 for a template that has a Bitbucket DC webhook configured and HTTP 403 otherwise. An unauthenticated remote attacker can use this response discrepancy as an oracle to enumerate which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured, without knowing the secret webhook_key.
