AI-suggested
Organizations should prioritize the following specific mitigation steps: 1) Immediately identify and inventory all instances of INVT VT-Designer version 2.1.13 within their environment, especially in OT and industrial control system (ICS) segments. 2) Restrict access to the software and its associated files to trusted users only, employing strict file handling policies to prevent opening untrusted PM3 files. 3) Implement network segmentation to isolate systems running VT-Designer from general IT networks and internet access to reduce exposure to malicious files or web content. 4) Educate users on the risks of opening files from unverified sources and the dangers of phishing attacks that could deliver malicious PM3 files or links. 5) Monitor for unusual process behavior or memory corruption indicators on hosts running VT-Designer using endpoint detection and response (EDR) tools tailored for OT environments. 6) Engage with INVT or authorized vendors to obtain patches or updates as soon as they become available, and plan for timely deployment. 7) Employ application whitelisting and restrict execution privileges to limit the impact of potential code execution. 8) Consider sandboxing or using virtual environments for opening PM3 files from external sources to contain potential exploitation attempts.
Description
INVT VT-Designer PM3 File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of INVT VT-Designer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PM3 files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25550.
