Title:	Apache Tomcat RCE Vulnerability (May 2020) - Linux
Summary:	Apache Tomcat is prone to a remote code execution (RCE); vulnerability.
Description:	Summary: Apache Tomcat is prone to a remote code execution (RCE) vulnerability. Vulnerability Insight: If: - an attacker is able to control the contents and name of a file on the server and - the server is configured to use the PersistenceManager with a FileStore and - 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 - 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 must be true for the attack to succeed. Affected Software/OS: Apache Tomcat 7.0.0 to 7.0.103, 8.5.0 to 8.5.54, 9.0.0.M1 to 9.0.34 and 10.0.0-M1 to 10.0.0-M4. Solution: Update to version 7.0.104, 8.5.55, 9.0.35, 10.0.0-M5 or later. CVSS Score: 4.4 CVSS Vector: AV:L/AC:M/Au:N/C:P/I:P/A:P
