Advisory: Apache Shiro RememberMe Padding Oracle Vulnerability
November 30, 2019
Vulnerability Description
In September 2019, Apache officially released a vulnerability topic “RememberMe Padding Oracle Vulnerability” numbered SHIRO-721.

An attacker can use the Legal RememberMe cookie as the Padding Oracle attack prefix to construct RememberMe to trigger a Java deserialization attack. The attacker does not need to know the RememberMe encryption key when executing an attack. Apache Shiro is a powerful and easy-to-use Java security framework for performing authentication, authorization, passwords, and session management. Recently, it has been found that the use of this vulnerability has been spread in a small scope, and relevant users should take measures to protect against this vulnerability as soon as possible.
