# SonicWall SonicOS virtual appliances: weak password hashing exposes a platform credential

Link for people: https://infrastack.ai/live/CVE-2026-19703 (this .md is for agents)

SonicOS virtual appliances use a weak password hash that, under specific conditions, can be exploited by an attacker who already has local access to disclose a platform credential. That credential grants access to a limited subset of platform settings.

_Summary, check and fix written by a model from the sources; labelled as such._
