CVE-2025-7228: 
VT Designer vulnerability analysis and mitigation

INVT VT-Designer contains a critical vulnerability (CVE-2025-7228) that was discovered in its PM3 file parsing functionality. The vulnerability was reported on March 5, 2025, and publicly disclosed on July 7, 2025, as a zero-day vulnerability due to lack of vendor response. This security flaw affects installations of INVT VT-Designer and requires user interaction for exploitation (Zero Day Initiative).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) that occurs during the parsing of PM3 files. The issue stems from inadequate validation of user-supplied data, which can result in a write operation beyond the bounds of an allocated data structure. The vulnerability has received a CVSS v3.0 base score of 7.8 (High), with the following vector: AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (Zero Day Initiative).

If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process on affected installations of INVT VT-Designer. The high CVSS score indicates severe potential impacts on confidentiality, integrity, and availability of the affected system (Zero Day Initiative).

Due to the nature of the vulnerability, the only recommended mitigation strategy is to restrict interaction with the product. No patches were available at the time of disclosure, as the vendor remained unresponsive despite multiple attempts to contact them through various channels, including ICS-CERT (Zero Day Initiative).

The Zero Day Initiative attempted to responsibly disclose the vulnerability by contacting the vendor's PSIRT team and later involving ICS-CERT. After multiple unsuccessful attempts to reach the vendor between August 2024 and June 2025, ZDI proceeded with publishing the advisory as a zero-day vulnerability (Zero Day Initiative).
