CVE-2020-8017· NVD / CVE Program· CNA suse

race condition on texlive-filesystem cron job allows for the deletion of unintended files

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: texlive (openSUSE:Leap 15.1) 2017.20170520-lp151.12.3.1; texlive-filesystem (openSUSE:Leap 15.1) 2017.135-lp151.8.6.1; texlive-filesystem (openSUSE:Tumbleweed) 2021.185.svn54495-52.2.

Low priority for now. Upgrade to texlive (openSUSE:Leap 15.1) 2017.20170520-lp151.12.3.1; texlive-filesystem (openSUSE:Leap 15.1) 2017.135-lp151.8.6.1; texlive-filesystem (openSUSE:Tumbleweed) 2021.185.svn54495-52.2 or later.

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.
