SonicWall Bug Affecting 800k Firewalls Was Partially Fixed

June 23, 2021

A recent find revealed that a critical stack-based Buffer Overflow vulnerability tracked as CVE-2020-5135 affected over 800,000 SonicWall VPNs that were not properly patched until now.

While Craig Young of Tripwire Vulnerability and Exposure Research Team (VERT) and Nikita Abramov were both credited for discovering and reporting the vulnerability, VERT stated after accessing Bleeping Computer that the previous fix for the vulnerability had been “unsuccessful.”

With a view to the new update, SonicWall has now published hints about the vulnerability with further information about the repaired versions.
