CVE-2019-10062

Name of the Vulnerable Software and Affected Versions Aurelia framework versions 1.x

Description The issue concerns the HTMLSanitizer class in the Aurelia framework, which is susceptible to XSS attacks. This is because the sanitizer only attempts to filter SCRIPT elements, allowing remote attackers to conduct XSS attacks via JavaScript code in attributes of other elements. Attackers can also exploit a bug in how the SCRIPT string is processed by splitting and nesting them.

Recommendations For Aurelia framework version 1.x, consider disabling the HTMLSanitizer class until a patch is available, and restrict the use of JavaScript code in attributes of various elements to minimize the risk of exploitation.
