WebEOC contains multiple cross-site scripting vulnerabilities that may allow a remote attacker to inject and execute arbitrary script using a vulnerable WebEOC site.


WebEOC is a web-based crisis information management application that provides functions to gather, coordinate, and disseminate information between emergency personnel and Emergency Operations Centers (EOC). WebEOC contains multiple cross-site scripting vulnerabilities in different web pages throughout the application. Cross-site scripting is a technique used to inject malicious script (JavaScript, VBScript, etc.) or HTML into a web page. More information about cross-site scripting can be found in CERT Advisory CA-2000-02.


A remote attacker may be able to use a vulnerable WebEOC site to execute arbitrary script. In addition, that attacker may be able to retrieve sensitive data from WebEOC site. This data may include any arbitrary information, such as authentication and medical information.



Version 6.0.2 corrects this vulnerability. According to ESi:

This vulnerability has been addressed in version 6.0.2. Validation checks have been added to all input fields that appeared to be vulnerable to cross-site scripting attacks.

Do not follow unsolicited links

In order to convince users to visit their sites, attackers often use URL encoding, IP address variations, long URLs, intentional misspellings, and other techniques to create misleading links. Do not click on unsolicited links received in email, instant messages, web forums, or internet relay chat (IRC) channels. Type URLs directly into the browser to avoid these misleading links. While these are generally good security practices, following these behaviors will not prevent exploitation of this vulnerability in all cases, particularly if a trusted site has been compromised or allows cross-site scripting.
