CVE-2019-3688· NVD / CVE Program· CNA suse

squid: /usr/sbin/pinger packaged with wrong permission

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.33% (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: squid (openSUSE:Leap 15.0) 4.9-lp150.13.1; permissions (openSUSE:Leap 15.1) 20181116-lp151.4.9.1; squid (openSUSE:Leap 15.1) 4.9-lp151.2.7.1.
  • Severity is disputed: the assigning authority (CNA) scores it 5.1, NVD 7.1.

Low priority for now. Upgrade to squid (openSUSE:Leap 15.0) 4.9-lp150.13.1; permissions (openSUSE:Leap 15.1) 20181116-lp151.4.9.1; squid (openSUSE:Leap 15.1) 4.9-lp151.2.7.1 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

The /usr/sbin/pinger binary packaged with squid in SUSE Linux Enterprise Server 15 before and including version 4.8-5.8.1 and in SUSE Linux Enterprise Server 12 before and including 3.5.21-26.17.1 had squid:root, 0750 permissions. This allowed an attacker that compromissed the squid user to gain persistence by changing the binary

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.

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.
