CVE-2019-11708: Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxe
Noroxi assessment
Priority: Now (action score 87/100)
- CISA has confirmed exploitation in the wild (May 23, 2022). Remediation deadline for US federal agencies: Jun 13, 2022.
- Probability of exploitation in the next 30 days: 55.8% (FIRST EPSS); higher than 99% of all records.
- 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.
- Fixed version: mozjs60 (Alpine:v3.10) 60.7.2-r0; firefox-esr (Debian:12) 60.7.2esr-1; thunderbird (Debian:12) 1:60.7.2-1.
Patch today or shut off access. Upgrade to mozjs60 (Alpine:v3.10) 60.7.2-r0; firefox-esr (Debian:12) 60.7.2esr-1; thunderbird (Debian:12) 1:60.7.2-1 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
