How the Exploit Works

The exploit takes advantage of an out-of-bounds write vulnerability in Adobe Framemaker. An attacker, by enticing a user to open a specially crafted malicious file, can cause the application to write data beyond the end of an allocated object. This can corrupt valid data and potentially lead to arbitrary code execution. The code would run in the context of the current user, and if the user has administrative privileges, the attacker could take control of the affected system.

Conceptual Example Code

Consider the following pseudocode illustrating how an attacker might create a malicious file to exploit this vulnerability:

function createMaliciousFile() {
// Create a new file
File file = new File("malicious.frmk");
// Write data that exceeds the allocated buffer size
for (int i = 0; i <= BUFFER_SIZE + 1; i++) {
file.write("malicious_data");
}
// Save the file
file.save();
// The file now contains data that, when opened in Adobe Framemaker,
// will result in an out-of-bounds write, leading potentially to arbitrary code execution.
}

In this conceptual example, “BUFFER_SIZE” represents the maximum amount of data that can safely be written to a file. By writing more data than this, the attacker creates a condition that can result in an out-of-bounds write when the file is opened in Adobe Framemaker. This is a simplified example, and actual exploit code would likely be more complex.
