Detail
Vulnerability Note VU#858993Deterministic Network Enhancer privilege escalation vulnerabilityOverviewThe Deterministic Network driver contains a privilege escalation vulnerability, which can allow a local attacker to execute code with kernel privileges.I. DescriptionDeterministic Networks provides a product called Deterministic Network Enhancer (DNE), which extends the Microsoft Windows networking stack. DNE is packaged with multiple applications, including the Cisco VPN Client. The DNE driver, which is provided by dne2000.sys, is vulnerable to privilege escalation. By making a certain ioctl to the DNE device driver, it is possible to execute code with windows kernel privileges.II. ImpactA local attacker may be able to execute code with windows kernel privileges.III. SolutionApply an updateThis issue is addressed in dne2000.sys version 3.21.12.17902.
