CVSS v3.1

Official 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

Technical Analysis

CVE-2012-5382 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2012-5382. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
