CVE-2022-27651: A flaw was found in buildah where containers were incorrectly started with non-empty default permissions.
Noroxi assessment
Priority: Monitor (action score 27/100)
- 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: 1.2% (FIRST EPSS); higher than 69.6% 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. Special conditions such as timing or configuration are required.
- Fixed version: aardvark-dns (AlmaLinux:8) 2:1.0.1-27.module_el8.6.0+2878+e681bc44; buildah (AlmaLinux:8) 1.11.6-10.module_el8.5.0+2635+e4386a39, 1.19.9-2.module_el8.5.0+2636+8c48f0fc, 1.11.6-10.module_el8.5.0+2842+7d0cf290; buildah-tests (AlmaLinux:8) 1.11.6-10.module_el8.5.0+2635+e4386a39, 1.19.9-2.module_el8.5.0+2636+8c48f0fc, 1.11.6-10.module_el8.5.0+2842+7d0cf290.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to aardvark-dns (AlmaLinux:8) 2:1.0.1-27.module_el8.6.0+2878+e681bc44; buildah (AlmaLinux:8) 1.11.6-10.module_el8.5.0+2635+e4386a39, 1.19.9-2.module_el8.5.0+2636+8c48f0fc, 1.11.6-10.module_el8.5.0+2842+7d0cf290; buildah-tests (AlmaLinux:8) 1.11.6-10.module_el8.5.0+2635+e4386a39, 1.19.9-2.module_el8.5.0+2636+8c48f0fc, 1.11.6-10.module_el8.5.0+2842+7d0cf290 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
A flaw was found in buildah where containers were incorrectly started with non-empty default permissions. A bug was found in Moby (Docker Engine) where containers were incorrectly started with non-empty inheritable Linux process capabilities, enabling an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. This has the potential to impact confidentiality and integrity.

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.
Credits

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.
