Security readout for executives and security teams
This flaw lets an attacker trick an administrator into opening a malicious management-console link, causing script to run inside the Symantec ASG or ProxySG console session. The main business risk is compromise of administrator trust and console actions, but the source bundle does not report active exploitation or a CVSS score. Exposure is likely limited to organizations running affected ASG or ProxySG versions and administrators who can access the management console. Risk is higher if console access is reachable from broad internal networks, VPN users, or the internet. The source bundle does not state exposure prerequisites beyond the management console. Prioritize remediation for appliances that still expose the management console to administrators over broad networks. This is not evidenced as actively exploited, but management-console XSS can affect privileged users and should not remain unresolved on security gateway infrastructure. Mitigation focus: Upgrade ASG 6.7 and ProxySG 6.7 to 6.7.2.1 or later.; Upgrade ProxySG 6.5 to 6.5.10.6 or later.; Check Symantec advisory SA155 for supported fixes for ASG 6.6 and ProxySG 6.6..
