Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.65% (FIRST EPSS); higher than 51.6% 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: firefox (AlmaLinux:8) 115.12.0-1.el8_10.alma.1; thunderbird (AlmaLinux:8) 115.12.1-1.el8_10.alma.1; firefox (AlmaLinux:9) 115.12.0-1.el9_4.alma.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to firefox (AlmaLinux:8) 115.12.0-1.el8_10.alma.1; thunderbird (AlmaLinux:8) 115.12.1-1.el8_10.alma.1; firefox (AlmaLinux:9) 115.12.0-1.el9_4.alma.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

By tricking the browser with a `X-Frame-Options` header, a sandboxed iframe could have presented a button that, if clicked by a user, would bypass restrictions to open a new window. This vulnerability affects Firefox < 127, Firefox ESR < 115.12, and Thunderbird < 115.12.
