RESTEasy: Use of the default exception handler in RESTEasy can lead to reflected XSS attack
Cross-site scripting (XSS) vulnerability in the default exception handler in RESTEasy allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
It was found that the default exception handler in RESTEasy did not properly validate user input. An attacker could use this flaw to launch a relected XSS attack.
Statement: This issue affects the versions of RESTEasy as shipped with Red Hat Satellite 6. Red Hat Product Security has rated this issue as having a security impact of Moderate. Additionally Red Hat Satellite does not use the default ExceptionMapper, and the custom exception handler does not allow return type of text/html. A future update may address this issue. Fo
