DLL Hijacking Assessment & Mitigation

Posted September 3, 2010    Marc Maiffret

There has been a lot of discussion lately about the older, but newly rediscovered, DLL Hijacking vulnerability. If you are not already familiar with this vulnerability, it allows for system compromise across an unknown number of applications. Specifically, the vulnerability takes advantage of the process of how Microsoft Windows applications load DLL (Dynamic-Link Library) files, which are required for most applications to function properly. Due to the way that Windows loads DLLs by default, it allows for certain scenarios where attackers could load their own DLLs containing malicious backdoor code and related.

Since the DLL Hijacking vulnerability is a logic / design flaw, any number of applications could be affected. This complicates the remediation process for organizations because there is not one simple patch to deploy, but rather many applications that require updates in order to mitigate and prevent this vulnerability.

eEye Vulnerability Management solutions go above and beyond preventing DLL Hijacking by not only assessing vulnerable applications but also preventing attacks against applications where no patch or standard remediation is possible.
