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

INVT VT-Designer contains a remote code execution vulnerability (CVE-2025-7228) discovered in July 2025. The vulnerability specifically affects the parsing of PM3 files in VT-Designer version 2.1.13. This security flaw was initially reported to Zero Day Initiative and subsequently disclosed as a zero-day vulnerability due to lack of vendor response (Zero Day Initiative).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) with a CVSS v3.0 base score of 7.8 (High). The vulnerability exists within the parsing of PM3 files and stems from improper validation of user-supplied data, which can result in a write operation past the end of an allocated data structure. The attack vector is local (AV:L) with low attack complexity (AC:L), requires no privileges (PR:N), but does need user interaction (UI:R) (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).

The vulnerability requires user interaction for exploitation, specifically requiring the target to visit a malicious page or open a malicious file. The local attack vector suggests that an attacker would need some form of local access or social engineering to successfully exploit the vulnerability (Zero Day Initiative).

Given the nature of the vulnerability and lack of vendor response, the only recommended mitigation strategy is to restrict interaction with the product. Multiple attempts were made to contact the vendor through various channels, including PSIRT contacts and ICS-CERT, between August 2024 and June 2025, but no patch was released (Zero Day Initiative).
