Technical details

A stored cross-site scripting (XSS) vulnerability exists within the dashboard layout component of the Arista Edge Threat Management (NGFW) web interface. The flaw stems from improper neutralization of user-supplied input (CWE-79), where unvalidated variables are echoed back into administrative profiles. An attacker with high privileges (PR:H) can exploit this over the network by injecting a malicious payload that executes in the context of another administrator's browser session. Successful exploitation requires user interaction (UI:R) and can result in high confidentiality impact, allowing for the theft of session tokens or sensitive configuration data.
