SonicWall SonicOS Improper Access Control Vulnerability | Ransomware |
Source: CISA Known Exploited Vulnerabilities catalog. The Ransomware flag reflects CISA's own knownRansomwareCampaignUse field, set when the CVE has been observed in ransomware campaigns per their threat intel. It's not a property of the vulnerability description itself.
Correlation is at the platform level, not per-OS-version. Not exhaustive: KEV only lists actively-exploited CVEs and many relevant unexploited vulnerabilities are not here. Verify against vendor security advisories (PSIRT, JSA, PAN-SA) and NVD before acting. See compensating controls if refresh isn't immediate.
SonicOS 7.1.x and 7.0.X Release Lifecycle
SonicOS 7.1.x and 7.0.X is a SonicWall SonicOS software release. Releases are maintained on a fixed schedule: SonicWall ships fixes and security patches until the release reaches end of engineering, after which a device must be upgraded to a maintained release to stay patchable. The dates below are milestones for the software train, not for any specific appliance — hardware running this release has its own separate lifecycle. This product has reached end of life as of , meaning SonicWall no longer provides technical support, software updates, or hardware replacement for this product. Organizations still running the SonicOS 7.1.x and 7.0.X should plan a migration .
