CVE-2012-5377
Status: ModifiedMedium (6)—
Untrusted search path vulnerability in the installation functionality in ActivePerl 5.16.1.1601, when installed in the top-level C:\ directory, allows local users to gain privileges via a Trojan horse DLL in the C:\Perl\Site\bin directory, which is added to the PATH system environment variable, 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.
CVSS
- Version: 2.0
- Vector: AV:L/AC:H/Au:S/C:C/I:C/A:C
- Base score: 6
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 1.27%
- Percentile among all scored CVEs: 69
- Score date: 10/4/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
