MediumCVSS 6.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.98% (FIRST EPSS); higher than 62.7% 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: dogtag-pki (Debian:11) 10.9.1-1; pki-base (Red Hat:enterprise_linux:7::client) 0:10.5.18-12.el7_9; pki-base-java (Red Hat:enterprise_linux:7::client) 0:10.5.18-12.el7_9.

Low priority for now. Upgrade to dogtag-pki (Debian:11) 10.9.1-1; pki-base (Red Hat:enterprise_linux:7::client) 0:10.5.18-12.el7_9; pki-base-java (Red Hat:enterprise_linux:7::client) 0:10.5.18-12.el7_9 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

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in the Key Recovery Authority (KRA) Agent Service in pki-core 10.10.5 where it did not properly sanitize the recovery ID during a key recovery request, enabling a reflected cross-site scripting (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted Javascript code.
