CVE-2008-5121
HighSummary
A vulnerability in the dne2000.sys driver in Citrix Deterministic Network Enhancer (DNE) versions 2.21.7.233 through 3.21.7.17464, used in Cisco VPN Client, Blue Coat WinProxy, and SafeNet SoftRemote and HighAssurance Remote, allows local users to gain privileges via a crafted DeviceIoControl request to the \.\DNE device interface.
Risk Assessment
A local attacker can gain elevated privileges, potentially leading to full system compromise, including malware installation, data theft, or escalation to other network resources.
Recommendation
Immediately update the DNE driver to the latest version available from the vendor (Citrix) or apply relevant security patches. If no update is available, consider temporarily disabling or restricting access to the \.\DNE interface.
