CVE-2019-0221: XSS
First published: Sat Apr 13 2019(Updated: )
Apache Tomcat is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the SSI printenv command. A remote attacker could exploit this vulnerability to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
