CVE-2022-31252: permissions: chkstat does not check for group-writable parent directories or target files in safeOpen()

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: permissions (openSUSE:Leap 15.3) 20200127-lp153.24.12.1; permissions (openSUSE:Leap 15.4) 20201225-150400.5.11.1; permissions (openSUSE:Leap Micro 5.2) 20181225-150200.23.15.1.

Low priority for now. Upgrade to permissions (openSUSE:Leap 15.3) 20200127-lp153.24.12.1; permissions (openSUSE:Leap 15.4) 20201225-150400.5.11.1; permissions (openSUSE:Leap Micro 5.2) 20181225-150200.23.15.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A Incorrect Authorization vulnerability in chkstat of SUSE Linux Enterprise Server 12-SP5; openSUSE Leap 15.3, openSUSE Leap 15.4, openSUSE Leap Micro 5.2 did not consider group writable path components, allowing local attackers with access to a group what can write to a location included in the path to a privileged binary to influence path resolution. This issue affects: SUSE Linux Enterprise Server 12-SP5 permissions versions prior to 20170707. openSUSE Leap 15.3 permissions versions prior to 20200127. openSUSE Leap 15.4 permissions versions prior to 20201225. openSUSE Leap Micro 5.2 permissions versions prior to 20181225.

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.

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.
