[ASA-202006-6] tomcat7: arbitrary code execution
Arch Linux Security Advisory ASA-202006-6 ========================================= Severity: High Date : 2020-06-06 CVE-ID : CVE-2020-9484 Package : tomcat7 Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1169 Summary ======= The package tomcat7 before version 7.0.104-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 7.0.104-1. # pacman -Syu "tomcat7>=7.0.104-1" The problem has been fixed upstream in version 7.0.104. Workaround ========== None. Description =========== 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. Impact ====== A remote attacker can execute code on the affected host if they control the file content and know the path.
