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.

The ftlserver component of TIBCO Software Inc.'s TIBCO FTL - Community Edition, TIBCO FTL - Developer Edition, TIBCO FTL - Enterprise Edition, TIBCO FTL - Enterprise Edition, TIBCO eFTL - Community Edition, TIBCO eFTL - Developer Edition, TIBCO eFTL - Enterprise Edition, and TIBCO eFTL - Enterprise Edition contains a difficult to exploit vulnerability that allows a low privileged attacker with local access to obtain user credentials to the affected system. Affected releases are TIBCO Software Inc.'s TIBCO FTL - Community Edition: versions 6.0.0 through 6.8.0, TIBCO FTL - Developer Edition: versions 6.0.1 through 6.8.0, TIBCO FTL - Enterprise Edition: versions 6.0.0 through 6.7.3, TIBCO FTL - Enterprise Edition: version 6.8.0, TIBCO eFTL - Community Edition: versions 6.0.0 through 6.8.0, TIBCO eFTL - Developer Edition: versions 6.0.1 through 6.8.0, TIBCO eFTL - Enterprise Edition: versions 6.0.0 through 6.7.3, and TIBCO eFTL - Enterprise Edition: version 6.8.0.

The eFTL Server component of TIBCO Software Inc.'s TIBCO eFTL - Community Edition, TIBCO eFTL - Developer Edition, and TIBCO eFTL - Enterprise Edition contains an easily exploitable vulnerability that allows clients to inherit the permissions of the client that initially connected on the affected system. Affected releases are TIBCO Software Inc.'s TIBCO eFTL - Community Edition: versions 6.7.2 and below, TIBCO eFTL - Developer Edition: versions 6.7.2 and below, and TIBCO eFTL - Enterprise Edition: versions 6.7.2 and below.

The eFTL Server component of TIBCO Software Inc.'s TIBCO eFTL - Community Edition, TIBCO eFTL - Developer Edition, and TIBCO eFTL - Enterprise Edition contains an easily exploitable vulnerability that allows a low privileged attacker with network access to generate API tokens that can access any other channel with arbitrary permissions. Affected releases are TIBCO Software Inc.'s TIBCO eFTL - Community Edition: versions 6.7.2 and below, TIBCO eFTL - Developer Edition: versions 6.7.2 and below, and TIBCO eFTL - Enterprise Edition: versions 6.7.2 and below.

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.

The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.

The FTL Server (tibftlserver) and Docker images containing tibftlserver components of TIBCO Software Inc.'s TIBCO ActiveSpaces - Community Edition, TIBCO ActiveSpaces - Developer Edition, TIBCO ActiveSpaces - Enterprise Edition, TIBCO FTL - Community Edition, TIBCO FTL - Developer Edition, TIBCO FTL - Enterprise Edition, TIBCO eFTL - Community Edition, TIBCO eFTL - Developer Edition, and TIBCO eFTL - Enterprise Edition contain a vulnerability that theoretically allows a non-administrative, authenticated FTL user to trick the affected components into creating illegitimate certificates. These maliciously generated certificates can be used to enable man-in-the-middle attacks or to escalate privileges so that the malicious user has administrative privileges. Affected releases are TIBCO Software Inc.'s TIBCO ActiveSpaces - Community Edition: versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.6.1, and 4.6.2, TIBCO ActiveSpaces - Developer Edition: versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.6.1, and 4.6.2, …

For Eclipse Jetty versions 9.4.37-9.4.42, 10.0.1-10.0.5 & 11.0.1-11.0.5, URIs can be crafted using some encoded characters to access the content of the WEB-INF directory and/or bypass some security constraints. This is a variation of the vulnerability reported in CVE-2021-28164/GHSA-v7ff-8wcx-gmc5.

When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected.

When reading a specially crafted TAR archive an Apache Ant build can be made to allocate large amounts of memory that finally leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Apache Ant prior to 1.9.16 and 1.10.11 were affected.
