A buffer overflow vulnerability in SonicOS allows a remote attacker to cause Denial of Service (DoS) and potentially execute arbitrary code by sending a malicious request to the firewall. This vulnerability affected SonicOS Gen 6 version 6.5.4.7, 6.5.1.12, 6.0.5.3, SonicOSv 6.5.4.v and Gen 7 version 7.0.0.0.

There’s high attacker value here if an attacker A) wants to cause a little mayhem, and/or B) can actually turn the DoS into reliable RCE. The first option is probably the likelier outcome in the immediate future. If Positive Technologies or Tripwire releases a PoC, the likelihood of broad exploitation probably rises significantly. For now, “patch fast but don’t panic” is good advice, as it always is with VPNs. There’s full analysis for this bug in the Rapid7 Analysis tab here.
