Technical Analysis

CVE-2015-2294 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
