SB2014042208 - Input validation error in Pimcore

Description

This security bulletin contains information about 1 vulnerability.

1) Input validation error (CVE-ID: CVE-2014-2922)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

The getObjectByToken function in Newsletter.php in the Pimcore_Tool_Newsletter module in pimcore 1.4.9 through 2.1.0 does not properly handle an object obtained by unserializing a pathname, which allows remote attackers to conduct PHP object injection attacks and delete arbitrary files via vectors involving a Zend_Http_Response_Stream object.

Remediation
