When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.

Multiple cross-site scripting (XSS) vulnerabilities in Tembria Server Monitor before 6.0.5 Build 2252 allow remote attackers to inject arbitrary web script or HTML via (1) the siteid parameter to logbook.asp, (2) the siteid parameter to monitor-events.asp, (3) the siteid parameter to reports-config-by-device.asp, (4) the siteid parameter to reports-config-by-monitor.asp, (5) the siteid parameter to reports-monitoring-queue.asp, (6) the action parameter to site-list.asp, the (7) siteid or (8) type parameter to event-history.asp, the (9) siteid or (10) type parameter to admin-history.asp, the (11) siteid or (12) id parameter to dashboard-view.asp, the (13) siteid or (14) dn parameter to device-events.asp, the (15) siteid or (16) submit parameter to device-finder.asp, the (17) siteid or (18) dn parameter to device-monitors.asp, the (19) siteid or (20) type parameter to device-views.asp, the (21) siteid or (22) type parameter to monitor-views.asp, the (23) siteid or (24) sel parameter to …

Tembria Server Monitor before 6.0.5 Build 2252 uses a substitution cipher to encrypt application credentials, which allows local users to obtain sensitive information by leveraging read access to (1) authentication.dat or (2) XML files in the Exports directory.
