CVE-2024-10461: In multipart/x-mixed-replace responses, `Content-Disposition: attachment` in the response header was not respected and did not force a downl

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: 0.59% (FIRST EPSS).
  • 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) 128.4.0-1.el8_10; thunderbird (AlmaLinux:8) 128.4.0-1.el8_10.alma.1; firefox (AlmaLinux:9) 128.4.0-1.el9_4, 128.4.0-1.el9_5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to firefox (AlmaLinux:8) 128.4.0-1.el8_10; thunderbird (AlmaLinux:8) 128.4.0-1.el8_10.alma.1; firefox (AlmaLinux:9) 128.4.0-1.el9_4, 128.4.0-1.el9_5 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

In multipart/x-mixed-replace responses, `Content-Disposition: attachment` in the response header was not respected and did not force a download, which could allow XSS attacks. This vulnerability affects Firefox < 132, Firefox ESR < 128.4, Thunderbird < 128.4, and Thunderbird < 132.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
