TITLE

McAfee Email and Web Security and McAfee Email Gateway Vulnerability in which important information is obtained

DESCRIPTION

McAfee Email and Web Security (EWS) 5.x before 5.5 Patch 6 and 5.6 before Patch 3, and McAfee Email Gateway (MEG) 7.0 before Patch 1, does not properly encrypt system-backup data, which makes it easier for remote authenticated users to obtain sensitive information by reading a backup file, as demonstrated by obtaining password hashes. McAfee Email and Web Security Appliance and Email Gateway are prone to a cross-site scripting vulnerability, multiple information-disclosure vulnerabilities, a directory-traversal vulnerability, a security-bypass vulnerability, and an insecure-encryption vulnerability. A remote attacker could leverage the cross-site scripting issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Exploiting the information-disclosure issues allow the attacker to view local files within the context of the Web server process. Exploiting the security-bypass vulnerability allows attackers to bypass security restrictions and obtain sensitive information or perform unauthorized actions. Exploiting the directory-traversal issue allows attackers to use directory-traversal strings to retrieve arbitrary files in the context of the affected application. Exploiting the insecure-encryption issue allows attackers to determine encryption keys, which may lead to further attacks. McAfee Email Gateway (MEG) is a suite of email security solutions from McAfee. The solution offers incoming threat protection, outgoing encryption, data loss prevention, and more. The vulnerability stems from incorrect encryption of system backup data . ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

This can be exploited to download arbitrary files from local resources via directory traversal sequences. 6) An unspecified error can be exploited to disclose the contents of files. Note: A weakness due to the server-side session remaining active has also been reported.
