CVSS base score: 9.8 (Critical) CISA · v3.1 · 9.8 (Critical) vendor CNA · v3.1
Two scores are shown because both the vendor's CVE Numbering Authority (CNA) and CISA's Vulnrichment program scored this vulnerability independently — a gap between them reflects differing judgments, not an error.
Sophos Firewall Code Injection Vulnerability
Vendor: Sophos Product: Firewall
A code injection vulnerability in the User Portal and Webadmin of Sophos Firewall allows for remote code execution.
Each milestone comes from a different source, so gaps between them are gaps in what those sources publish, not evidence that nothing happened. EPSS history for this CVE holds 221 points from 2022-09-24, tracked daily from 2026-09-09; earlier points are weekly, which dates a spike to within a week. Peak probability 98.9% on 2026-06-20.
Check whether a specific version is affected →
What each source publishes about which product versions carry this vulnerability, kept as written rather than merged. Absence here means no source has published applicability data, not that nothing is affected.
No mentions found in monitored research blogs or news feeds.
Coverage across public collections only: Nuclei and OpenVAS NVT (scan);
Snort and Suricata ET Open (network); Sigma and YARA (host/SIEM);
Metasploit, Exploit-DB and public GitHub repositories (exploit). Absence
here means nothing public was found, not that detection is impossible.
GitHub PoC repositories are collected automatically by
PoC-in-GitHub (CC0) and are not vetted:
some are fakes and some are malware. Treat them as evidence that code was
published, not as code to run.
OpenVAS coverage derives from the Greenbone Community Feed, made available
