CVE-2020-8022 — User-writeable configuration file /usr/lib/tmpfiles.d/tomcat.conf allows for escalation of priviliges

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

CISA SSVC assessment CISA

Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

1. Identify exposed assets running the affected vendor/product/version combinations (Apache Software Foundation Tomcat, Opensuse Leap, SUSE SUSE Enterprise Storage 5…).
2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.

• Local/physical vector: focus on endpoint telemetry (EDR) from affected hosts.
• Audit administrative actions and access to resources outside each user’s normal pattern.

What should defenders know first?

CVE-2020-8022 is "User-writeable configuration file /usr/lib/tmpfiles.d/tomcat.conf allows for escalation of priviliges", rated High. It affects Tomcat (Apache Software Foundation); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.8 describes technical severity. EPSS 0.86% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
