CVE-2022-0532· NVD / CVE Program· CNA redhat

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier.

Noroxi assessment

Priority: Monitor (action score 16/100)

  • 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: 0.76% (FIRST EPSS); higher than 54.5% 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: github.com/cri-o/cri-o (Go) 1.23.1; cri-o (Red Hat:openshift:4.6::el7) 0:1.19.5-3.rhaos4.6.git91f8458.el7; cri-o-debuginfo (Red Hat:openshift:4.6::el7) 0:1.19.5-3.rhaos4.6.git91f8458.el7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to github.com/cri-o/cri-o (Go) 1.23.1; cri-o (Red Hat:openshift:4.6::el7) 0:1.19.5-3.rhaos4.6.git91f8458.el7; cri-o-debuginfo (Red Hat:openshift:4.6::el7) 0:1.19.5-3.rhaos4.6.git91f8458.el7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace.

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.

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.

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.
