SCA: security update for org.apache.tomcat.embed:tomcat-embed-core, org.apache.tomcat:tomcat-catalina (GHSA-344f-f5vg-2jfj)

high Tenable Self-Hosted Container Security Plugin ID 422695

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to
 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the
 server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is
 configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used)
 or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker
 knows the relative file path from the storage location used by FileStore to the file the attacker has
 control over; then, using a specifically crafted request, the attacker will be able to trigger remote code
 execution via deserialization of the file under their control. Note that all of conditions a) to d) must
 be true for the attack to succeed. (CVE-2020-9484)

Solution

Update the org.apache.tomcat.embed:tomcat-embed-core library and its related packages to version 10.0.0-M5 or later.
