Summary

Multiple W&T devices are shipped with a jQuery version with a known XSS vulnerability.

Severity

Weakness
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CWE-79)
Summary

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
