CVE-2020-9484

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.

tomcat使用了自带session同步功能时,不安全的配置(没有使用EncryptInterceptor)导致存在的反序列化漏洞,通过精心构造的数据包, 可以对使用了tomcat自带session同步功能的服务器进行攻击。PS:这个不是CVE-2020-9484,9484是session持久化的洞,这个是session集群同步的洞!

A smol bash script I threw together pretty quickly to scan for vulnerable versions of the Apache Tomcat RCE. I'll give it some love when I have the time.
