Title
Unauthenticated XML External Entity Injection in AOS-8 Instant allows Denial of Service
Summary
A vulnerability in the XML handling component of AOS-8 DHCP services could allow an unauthenticated remote attacker to trigger a denial-of-service condition. Successful exploitation could allow an attacker to cause excessive resource consumption upon user interaction, leading to service disruption or reduced availability of the affected system.
NOTE: This vulnerability only impacts Access Points running AOS Instant 8.x.x.x
