CVE-2022-3172· NVD / CVE Program· CNA kubernetes

Kubernetes - API server - Aggregated API server can cause clients to be redirected (SSRF)

Noroxi assessment

Priority: Monitor (action score 33/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.4% (FIRST EPSS); higher than 84.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: kubernetes (Debian:12) 1.20.5+really1.20.2-1; crudini (Red Hat:openshift_ironic:4.12::el9) 0:0.9.3-4.el9; future (Red Hat:openshift_ironic:4.12::el9) 0:0.18.2-9.el9.1.
  • Severity is disputed: the assigning authority (CNA) scores it 5.1, NVD 8.2.

Low priority for now. Upgrade to kubernetes (Debian:12) 1.20.5+really1.20.2-1; crudini (Red Hat:openshift_ironic:4.12::el9) 0:0.9.3-4.el9; future (Red Hat:openshift_ironic:4.12::el9) 0:0.18.2-9.el9.1 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 security issue was discovered in kube-apiserver that allows an aggregated API server to redirect client traffic to any URL. This could lead to the client performing unexpected actions as well as forwarding the client's API server credentials to third parties.

Affected versions

NVD version ranges (for catalog products). Add the product to your stack with a version and matching uses these.

  • kubernetes apiserverup to 1.21.14 inclusive
  • kubernetes apiserver1.22.0 and later · before 1.22.14
  • kubernetes apiserver1.23.0 and later · before 1.23.11
  • kubernetes apiserver1.24.0 and later · before 1.24.5
  • kubernetes apiserver1.25.0

Versions reported by the vendor

Affected version ranges reported by the assigning authority (kubernetes). Independent of NVD's CPE analysis and usually ahead of it.

Exploit status

Proof of concept available

A public proof of concept or detection signature exists. Exploit knowledge is out there; don't delay patching.

Evidence

  • Proof-of-concept repository on GitHub ×1

Noroxi does not host or link to exploit code. Metasploit module names and Nuclei template ids are shown (names, not code); Exploit-DB entries and PoC repositories are given as counts only.

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.
