CVE-2016-4437 Details
Description
Apache Shiro before 1.2.5, when a cipher key has not been configured for the "remember me" feature, allows remote attackers to execute arbitrary code or bypass intended access restrictions via an unspecified request parameter.
A remote code execution vulnerability exists in Apache Shiro versions prior to 1.2.5. When the 'remember me' feature is enabled but no cipher key is configured, remote attackers can exploit this vulnerability by sending a crafted request parameter. This exploitation can lead to arbitrary code execution or bypassing access restrictions.
Users are advised to upgrade to Apache Shiro version 1.2.5 or later, configure a secret cipher key for the 'remember me' feature, or disable the 'remember me' feature altogether.
