CVE-2025-7229: 
VT Designer vulnerability analysis and mitigation

INVT VT-Designer PM3 File Parsing vulnerability (CVE-2025-7229) is a remote code execution vulnerability discovered in INVT VT-Designer version 2.1.13. The vulnerability was initially reported on March 5, 2025, and was publicly disclosed on July 7, 2025, as a zero-day vulnerability. This security flaw specifically affects the parsing mechanism of PM3 files in the software (Zero Day Initiative).

The vulnerability is classified as an Out-of-bounds Write (CWE-787) that occurs during the parsing of PM3 files. The root cause is attributed to improper validation of user-supplied data, which can result in a write operation past the end of an allocated data structure. The vulnerability has received a CVSS v3.0 base score of 7.8 (High), with the vector string CVSS:3.0/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).

The vulnerability requires user interaction for exploitation, specifically the target must visit a malicious page or open a malicious file. The attack complexity is considered low, requiring no privileges for execution, though it does need local access (Zero Day Initiative).

Due to the nature of the vulnerability, the only recommended mitigation strategy is to restrict interaction with the product. Multiple attempts were made to contact the vendor through various channels, including ICS-CERT, between March and June 2025, but no official patch was released at the time of disclosure (Zero Day Initiative).
