CVE-2024-10462: Truncation of a long URL could have allowed origin spoofing in a permission prompt.
Noroxi assessment
Priority: Monitor (action score 26/100)
- 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: 0.56% (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.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- 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_5, 128.4.0-1.el9_4.
- 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_5, 128.4.0-1.el9_4 or later.
