User-context code execution via VBScript object mishandling
Published Mar 12, 2020 · Updated Aug 4, 2024
Memory corruption in Microsoft Internet Explorer 9 and 11 allows remote attackers to execute code through crafted web content. The VBScript engine mishandles objects in memory, corrupting browser process state while processing malicious script content. Exploitation requires a user to open an attacker-controlled or compromised webpage, and resulting code runs with the current user's rights.
