A fixed version is listed under Patch Availability — apply it.

An insufficient entropy vulnerability exists in the salt generation functionality of WWBN AVideo dev master commit 15fed957fb. A specially crafted series of HTTP requests can lead to privilege escalation. An attacker can gather system information via HTTP requests and brute force the salt offline, leading to forging a legitimate password recovery code for the admin user.

A fixed version is listed under Patch Availability. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
