A vulnerability found in nss.
Noroxi assessment
Priority: Monitor (action score 30/100)
- 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: 0.94% (FIRST EPSS); higher than 60.1% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: nss (Debian:12) 2:3.87-1; mozilla-nss (SUSE:Linux Enterprise High Performance Computing 15 SP1-LTSS) 3.79.3-150000.3.90.1; mozilla-nss (SUSE:Linux Enterprise Micro 5.3) 3.79.3-150400.3.23.1.
Low priority for now. Upgrade to nss (Debian:12) 2:3.87-1; mozilla-nss (SUSE:Linux Enterprise High Performance Computing 15 SP1-LTSS) 3.79.3-150000.3.90.1; mozilla-nss (SUSE:Linux Enterprise Micro 5.3) 3.79.3-150400.3.23.1 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
A vulnerability found in nss. By this security vulnerability, nss client auth crash without a user certificate in the database and this can lead us to a segmentation fault or crash.

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.
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 researchersFinders, 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.
