CVE-2022-47951· NVD / CVE Program· CNA mitre

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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% (FIRST EPSS); higher than 63.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: cinder (Debian:10) 2:13.0.7-1+deb10u2; glance (Debian:10) 2:17.0.0-5+deb10u1; nova (Debian:10) 2:18.1.0-6+deb10u2.

Low priority for now. Upgrade to cinder (Debian:10) 2:13.0.7-1+deb10u2; glance (Debian:10) 2:17.0.0-5+deb10u1; nova (Debian:10) 2:18.1.0-6+deb10u2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.

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.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

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.

Technical details

Attack conditions

  • Anyone who can reach it over the internet can trigger it.
  • A low-privileged account is enough.
  • A user must open a link or visit a page.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.
