CVE-2024-0750· NVD / CVE Program· CNA mozilla

A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user into granting permissions.

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.83% (FIRST EPSS); higher than 56.9% 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) 115.7.0-1.el8_9.alma.1; thunderbird (AlmaLinux:8) 115.7.0-1.el8_9.alma.1; firefox (AlmaLinux:9) 115.7.0-1.el9_3.alma.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to firefox (AlmaLinux:8) 115.7.0-1.el8_9.alma.1; thunderbird (AlmaLinux:8) 115.7.0-1.el8_9.alma.1; firefox (AlmaLinux:9) 115.7.0-1.el9_3.alma or later.
