CVE-2024-6612: CSP violation leakage when using devtools

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: 0.49% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: MozillaFirefox (openSUSE:Leap 15.5) 128.1.0-150200.152.146.1; MozillaFirefox-branding-SLE (openSUSE:Leap 15.5) 128-150200.9.16.1; MozillaThunderbird (openSUSE:Leap 15.5) 128.2.3-150200.8.177.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to MozillaFirefox (openSUSE:Leap 15.5) 128.1.0-150200.152.146.1; MozillaFirefox-branding-SLE (openSUSE:Leap 15.5) 128-150200.9.16.1; MozillaThunderbird (openSUSE:Leap 15.5) 128.2.3-150200.8.177.1 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

CSP violations generated links in the console tab of the developer tools, pointing to the violating resource. This caused a DNS prefetch which leaked that a CSP violation happened. This vulnerability affects Firefox < 128 and Thunderbird < 128.
