Summary

CVE-2026-4415 is a high-severity Relative Path Traversal (CWE-23) vulnerability in Gigabyte Control Center. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 30.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 CM-7 (Least Functionality) and SI-10 (Information Input Validation).

Threat & Defense at a Glance

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates the relative path traversal (CWE-23) and out-of-bounds write (CWE-787) by validating file path inputs to the pairing feature, preventing arbitrary file writes.

CM-7 Least Functionality good match

prevent

Restricts Gigabyte Control Center to least functionality by disabling the unnecessary pairing feature, eliminating the unauthenticated remote attack vector.

SI-2 Flaw Remediation good match

prevent

Ensures identification, reporting, and correction of the arbitrary file write flaw in Gigabyte Control Center through timely patching or vendor updates.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

Why these techniques?

Unauthenticated remote exploitation over the network of Gigabyte Control Center's pairing feature enables initial access via public-facing application exploitation (T1190) and privilege escalation through arbitrary file writes leading to code execution (T1068).

escalation.

Deeper analysisAI

CVE-2026-4415 is an Arbitrary File Write vulnerability in Gigabyte Control Center, software developed by GIGABYTE. The issue arises when the pairing feature is enabled, allowing unauthenticated remote attackers to write arbitrary files to any location on the underlying operating system. This can lead to arbitrary code execution or privilege escalation. The vulnerability has a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-23 (Relative Path Traversal) and CWE-787 (Out-of-bounds Write). It was published on 2026-03-30.

Unauthenticated remote attackers can exploit this vulnerability over the network if the pairing feature is active in Gigabyte Control Center. Exploitation requires high attack complexity but no privileges or user interaction. Successful attacks enable writing files to arbitrary locations, potentially resulting in arbitrary code execution or privilege escalation on the affected system.
