CVE-2025-7227 is an Out-Of-Bounds Write Remote Code Execution vulnerability affecting INVT VT-Designer software. The vulnerability was discovered on March 5, 2025, and publicly disclosed on July 7, 2025, as a zero-day vulnerability. It affects INVT VT-Designer version 2.1.13 and allows remote attackers to execute arbitrary code on affected installations (Zero Day Initiative, NVD).

The vulnerability exists within the parsing of PM3 files and is classified as CWE-787 (Out-of-bounds Write). The issue stems from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. The vulnerability has been assigned 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).

An attacker who successfully exploits this vulnerability can execute arbitrary code in the context of the current process. The vulnerability requires user interaction, specifically that the target must visit a malicious page or open a malicious file (NVD).

The vulnerability requires user interaction for successful exploitation. An attacker needs to convince a user to visit a malicious page or open a malicious file containing the exploit. The vulnerability was disclosed as a zero-day, indicating that it was publicly disclosed before a patch was available (Zero Day Initiative).

Given 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 different channels, including ICS-CERT, but no official patch was released at the time of disclosure (Zero Day Initiative).
