CVE-2026-97732
Quick assessment
Affected
IRONMACE Ironshield
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
IRONMACE Ironshield 1.0.0.167 包含一个名为 tvk.sys 的内核模式驱动程序，该驱动程序在验证客户端可执行文件时，仅通过检查 WIN_CERTIFICATE 数据中是否存在预期的发布者和根证书字符串（“IRONMACE Co., Ltd.” 和 “DigiCert Trusted Root G4”）来进行身份验证，而未对 PKCS 签名数据进行解析和校验。因此，本地未授权的攻击者可通过构造恶意证书数据绕过此验证机制，从而获取对特权 IOCTL 功能的访问权限。

Vulnerability Description
IRONMACE Ironshield 1.0.0.167 has a tvk.sys kernel-mode driver that authenticates client executables by checking for expected publisher and root-certificate strings in WIN_CERTIFICATE data ("IRONMACE Co., Ltd." and "DigiCert Trusted Root G4") instead of parsing and validating the PKCS signature data. As a result, a local unprivileged attacker may bypass this via crafted certificate data and obtain access to privileged IOCTL functionality.
