Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

ABB will not be releasing updated firmware, as both GATE-E1 and GATE-E2 have reached end of life (EOL).  ABB recommends implementing defense-in-depth principles to minimize the risk that vulnerabilities are exploited.

• Separate control system networks from other networks using firewall and managed switches that have minimal number of ports exposed. 
• Physically protect control system from unauthorized personnel.
• Portable computers and removable storage should be scanned for viruses before connected to control system.

Vulnerable software versions

GATE-E2: All versions
