Vulnerability Information

Severity: High
Vulnerability Published: 2016-06-03
Patch Published: 2016-05-18
CVE [?]: CVE-2016-4437
CPE [?]: cpe:/a:apache:shiro

Synopsis

A Java security framework uses a default cipher key.

Description

The Apache Shiro uses a default cipher key for the 'remember me' feature when not explicitly configured. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code or access content that would otherwise be protected by a security constraint.

Solution

Upgrade to Apache Shiro 1.2.5 or later, ensure a secret cipher key is configured, or disable the 'remember me' feature.
