Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 2.6% (FIRST EPSS); higher than 84.9% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: cups (Debian:12) 1.1.99.b1.r4748-1; cups (Red Hat:enterprise_linux:3::as) 1:1.1.17-13.3.62; cups-debuginfo (Red Hat:enterprise_linux:3::as) 1:1.1.17-13.3.62.
Low priority for now. Upgrade to cups (Debian:12) 1.1.99.b1.r4748-1; cups (Red Hat:enterprise_linux:3::as) 1:1.1.17-13.3.62; cups-debuginfo (Red Hat:enterprise_linux:3::as) 1:1.1.17-13.3.62 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
The directory-services functionality in the scheduler in CUPS 1.1.17 and 1.1.22 allows remote attackers to cause a denial of service (cupsd daemon outage or crash) via manipulations of the timing of CUPS browse packets, related to a "pointer use-after-delete flaw."

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.
