CVE-2019-18901· NVD / CVE Program· CNA suse

mysql-systemd-helper allows setting 640 permissions of arbitrary files

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: 0.38% (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: mariadb (openSUSE:Leap 15.1) 10.2.31-lp151.2.12.1; ardana-cinder (SUSE:HPE Helion OpenStack 8) 8.0+git.1579279939.ee7da88-3.39.3; ardana-cobbler (SUSE:HPE Helion OpenStack 8) 8.0+git.1575037115.0326803-3.41.3.

Low priority for now. Upgrade to mariadb (openSUSE:Leap 15.1) 10.2.31-lp151.2.12.1; ardana-cinder (SUSE:HPE Helion OpenStack 8) 8.0+git.1579279939.ee7da88-3.39.3; ardana-cobbler (SUSE:HPE Helion OpenStack 8) 8.0+git.1575037115.0326803-3.41.3 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

A UNIX Symbolic Link (Symlink) Following vulnerability in the mysql-systemd-helper of the mariadb packaging of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15 allows local attackers to change the permissions of arbitrary files to 0640. This issue affects: SUSE Linux Enterprise Server 12 mariadb versions prior to 10.2.31-3.25.1. SUSE Linux Enterprise Server 15 mariadb versions prior to 10.2.31-3.26.1.

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.

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.
