Untrusted search path vulnerability in (1) WSAdminServer and (2) WSWebServer in Kerio WebSTAR (4D WebSTAR Server Suite) 5.4.2 and earlier allows local users with webstar privileges to gain root privileges via a malicious libucache.dylib helper library in the current working directory.

Security readout for executives and security teams

CVE-2006-6131 is a legacy local privilege-escalation flaw in Kerio WebSTAR/4D WebSTAR Server Suite. A user or process already running with webstar privileges could cause server components to load an untrusted helper library and gain root privileges. Exposure is most likely limited to legacy systems still running Kerio WebSTAR or 4D WebSTAR Server Suite 5.4.2 or earlier. The source bundle does not show broad internet-facing exploitability; the prerequisite is local access with webstar privileges. Treat this as high priority only if legacy WebSTAR remains in use. It requires local webstar-level access, but successful exploitation can produce root compromise, making unsupported exposed servers a material operational risk. Mitigation focus: Identify and retire Kerio WebSTAR or 4D WebSTAR 5.4.2 and earlier installations.; Check vendor or maintainer guidance for available updates or supported migration paths.; Restrict local shell and file-write access for accounts tied to WebSTAR services..
