Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2012-5382.

AI-analyzed exploit summary This Metasploit module exploits a missing DLL (wlbsctrl.dll) loaded by the IKEEXT service, which runs as SYSTEM. It leverages an insecure bin path to plant a malicious DLL, achieving local privilege escalation on vulnerable Windows systems.

Description

Untrusted search path vulnerability in the installation functionality in Zend Server 5.6.0 SP4, when installed in the top-level C:\ directory, might allow local users to gain privileges via a Trojan horse DLL in the C:\Zend\ZendServer\share\ZendFramework\bin directory, which may be added to the PATH system environment variable by an administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview. NOTE: CVE disputes this issue because the choice of C:\ (and the resulting unsafe PATH) is established by an administrative action that is not a default part of the Zend Server installation
