Reflected XSS in PaperCut NG/MF

Noroxi assessment

Priority: Plan (action score 42/100)

  • 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: 61.4% (FIRST EPSS); higher than 99.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: PaperCut PaperCut NG, PaperCut MF 20.1.10, 21.2.14, 22.1.5.

Add it to your regular patch cycle. Upgrade to PaperCut PaperCut NG, PaperCut MF 20.1.10, 21.2.14, 22.1.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

This is a reflected cross site scripting vulnerability in the PaperCut NG/MF application server. An attacker can exploit this weakness by crafting a malicious URL that contains a script. When an unsuspecting user clicks on this malicious link, it could potentially lead to limited loss of confidentiality, integrity or availability.
