CVE-2026-73781: Vulnerability in Hewlett Packard Enterprise (HPE) AOS-CX

This vulnerability involves a stored cross-site scripting (CWE-79) flaw in the web-based management interface of HPE AOS-CX. An attacker with authentication can inject malicious script code that executes in the browser of an administrative user accessing the interface. The CVSS 3.1 score is 8.4, reflecting network attack vector, low attack complexity, high privileges required, user interaction required, scope change, and high impact on confidentiality, integrity, and availability. The affected versions explicitly include 10.10.0000, 10.13.0000, 10.16.0000, 10.17.0000, and 10.18.0000.

An authenticated attacker can exploit this vulnerability to execute arbitrary scripts in an administrative user's browser within the management interface context. This can lead to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of the management system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict administrative interface access to trusted users and networks, and ensure strong authentication controls are in place.
