Deeper analysis
CVE-2026-23813 is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) published on 2026-03-11, affecting the web-based management interface of AOS-CX switches. Classified under CWE-287 (Improper Authentication), it enables an unauthenticated remote actor to circumvent existing authentication controls. In some cases, this bypass allows resetting the admin password, providing a pathway to unauthorized administrative access.
Any unauthenticated attacker with network access to the management interface can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation could achieve high impacts on confidentiality, integrity, and availability, such as gaining full administrative control over the switch through password reset, potentially leading to complete device compromise.
Mitigation details and patches are outlined in the HPE security advisory available at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05027en_us&docLocale=en_US.
