Detail

IronPort PXE Encryption is an e-mail encryption solution that is designed to secure e-mail communications without the need for a Public Key Infrastructure (PKI) or special agents on receiving systems. When an e-mail message is targeted for encryption, the PXE encryption engine on an IronPort e-mail gateway encrypts the original e-mail message as an HTML file and attaches it to a notification e-mail message that is sent to the recipient. The per-message key used to decrypt the HTML file attachment is stored on a local IronPort Encryption Appliance, PostX software installation or the Cisco Registered Envelope Service, which is a Cisco-managed software service.

PXE Encryption Privacy Vulnerabilities

The IronPort PXE Encryption solution is affected by two vulnerabilities that could allow unauthorized individuals to view the contents of secure e-mail messages. To exploit the vulnerabilities, attackers must first intercept secure e-mail messages on the network or via a compromised e-mail account.

IronPort Encryption Appliance Administration Interface Vulnerabilities

IronPort Encryption Appliance devices contain two vulnerabilities that could allow unauthorized users to gain access to the IronPort Encryption Appliance administration interface and modify other users' settings. These vulnerabilities do not affect Cisco Registered Envelope Service users.

Cisco has released free software updates that address these vulnerabilities. There are no workarounds for the vulnerabilities that are described in this advisory.

Id Description
51398 Cisco IronPort Products Admin Interface CSRF Arbitrary Command Execution

Cisco IronPort Appliances (PostX and Encryption Appliance) contain a flaw that allows a remote Cross-Site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application does not require multiple steps and/or confirmation for sensitive transactions for administrative preferences. A victim visiting a page with a specially crafted and embedded URL would be forced into a transaction they had not authorized taking advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into executing arbitrary commands in the context of their session with the application, without further prompting or verification.
