Report ID: 2024-279
An improper input validation issue exists in Microsoft Access, specifically MSACCESS.EXE version 16.0.18227.20162 when opening a specially crafted file. By sending a target the file and convincing them to open it, an attacker could unlikely gain Remote Code Execution (RCE) on the target's computer due to the unpatched issue. However, even if RCE isn't achieved, the crash could result in Denial of Service (DoS) for the target application. In addition, likely due to how Microsoft Access handles recent files, file recovery, and file repair, it is possible the issue could result in a persistent DoS attack, where the application will continue to crash, even after reboot by the target.
