Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.60% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenStack Keystone 27.0.3, 28.0.3, 29.0.3.

Low priority for now. Upgrade to OpenStack Keystone 27.0.3, 28.0.3, 29.0.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In OpenStack Keystone before 29.0.3, tokens obtained via delegated authentication mechanisms (OAuth1 access tokens, application credentials, trusts) could be submitted to the token-method authentication path for reauthentication to escape their intended project scope. When an application credential token was presented with no explicit scope, Keystone would issue a new token scoped to the credential owner's default project rather than the project for which the credential was issued, bypassing the intended project boundary. All Keystone deployments that permit delegated authentication through OAuth1 access tokens, application credentials, or trusts are affected.
