Gigabyte Control Center Security Flaws

Remote code execution and privilege escalation in Gigabyte Control Center allows unauthenticated network attackers to write arbitrary files to any system location when the pairing feature is enabled. This path traversal vulnerability (CWE-23) requires high attack complexity but needs no user interaction. No public exploit identified at time of analysis, though the technical details disclosed by Taiwan CERT provide sufficient information for exploitation development. CVSS 8.1 (High) reflects significant impact across confidentiality, integrity, and availability.

Insecure deserialization in Gigabyte Control Center's Performance Library component allows authenticated local users to escalate privileges to SYSTEM by sending crafted serialized payloads to the EasyTune Engine service. Affecting Gigabyte Performance Library across versions, this CWE-502 flaw enables low-privileged users to gain complete control of the Windows system. EPSS data not available; no public exploit identified at time of analysis, though the local attack vector and low complexity (CVSS:3.1/AV:L/AC:L/PR:L) suggest exploitation is technically straightforward for attackers with initial local access.
