Noroxi assessment
Priority: Now (action score 86/100)
- CISA has confirmed exploitation in the wild (Mar 28, 2022). Remediation deadline for US federal agencies: Apr 18, 2022.
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 69% (FIRST EPSS); higher than 99.3% 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: icedove (Debian:7) 17.0.7-1~deb7u1; iceweasel (Debian:7) 17.0.7esr-1~deb7u1; firefox (Red Hat:enterprise_linux:5::server) 0:17.0.7-1.el5_9.
Patch today or shut off access. Upgrade to icedove (Debian:7) 17.0.7-1~deb7u1; iceweasel (Debian:7) 17.0.7esr-1~deb7u1; firefox (Red Hat:enterprise_linux:5::server) 0:17.0.7-1.el5_9 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 · CISA KEV · FIRST EPSS
Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.

Vulnrichment: CISA's decision-tree inputs.
Actively exploited in the wild
CISA added this to its Known Exploited Vulnerabilities catalog on Mar 28, 2022. That signals real attacks, not theory.
Remediation deadline for US federal agencies: Apr 18, 2022.
