CyberLink StreamAuthor Insecure Library Loading Vulnerability

Date Disclosed:
9/3/2012

Date Patched:
No patch available.

Vendor:
CyberLink

Affected Software:
StreamAuthor 4.0 build 3308

Description:
StreamAuthor insecurely loads mfc71loc.dll and mfc71enu.dll. If an attacker convinces a user to open STA or STP files on an attacker-controlled WebDAV or SMB share, the vulnerability would be exploited, granting the attacker the ability to execute arbitrary code.

Severity:
High

Code Execution:
Yes.

Impact:
Remote Code Execution
This client-side vulnerability could allow an attacker to gain the ability to execute remote arbitrary code with the same permissions as the user that is currently logged in. If the user is an administrator, the attacker could install malicious software and further compromise the system.

Mitigation:
Block ports 139 and 445 at the perimeter firewall, prevent the WebClient service from running, and prevent DLLs from being loaded from WebDAV and remote shares.

Protection:
BeyondTrust's Retina® Network Security Scanner scans devices to detect for this vulnerability.
