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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2016-4437)

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-7139-1 advisory.

    It was discovered that Apache Shiro used a static cipher within the Remember Me feature inside     authentication by default. An attacker could possibly use this issue to achieve remote code execution or     obtain sensitive information.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.
