Title
Authenticated Stored Cross-Site Scripting Vulnerability (XSS) in AOS-CX Web-Based Management Interface
Summary
A vulnerability in the web-based management interface of AOS-CX could allow an authenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against an administrative user of the interface. A successful exploit allows an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface.
