CVE-2023-2088: A flaw was found in OpenStack due to an inconsistency between Cinder and Nova.

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 1.1% (FIRST EPSS); higher than 68.2% of all records.
  • 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: cinder (Debian:11) 2:17.4.0-1~deb11u2; cinder (Debian:12) 2:21.1.0-3; nova (Debian:12) 2:26.1.0-4.

Low priority for now. Upgrade to cinder (Debian:11) 2:17.4.0-1~deb11u2; cinder (Debian:12) 2:21.1.0-3; nova (Debian:12) 2:26.1.0-4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in OpenStack due to an inconsistency between Cinder and Nova. This issue can be triggered intentionally or by accident. A remote, authenticated attacker could exploit this vulnerability by detaching one of their volumes from Cinder. The highest impact is to confidentiality.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
