CVE-2021-28164: Input Validation

First published: Thu Apr 01 2021(Updated: )

Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by improper input validation by the default compliance mode. By sending specially-crafted requests with URIs that contain %2e or %2e%2e segments, an attacker could exploit this vulnerability to access protected resources within the WEB-INF directory, and use this information to launch further attacks against the affected system.
