Overview
The vulnerability CVE-2025-47128 is a significant security flaw identified in Adobe Framemaker versions 2020.8, 2022.6 and earlier. This vulnerability stems from an Integer Underflow (Wrap or Wraparound) issue that opens the door to potential arbitrary code execution. It is of particular concern as it impacts a broad range of systems running the affected Adobe Framemaker versions.
The implication of this vulnerability is considerable, given that exploitation could result in system compromise or data leakage. More alarmingly, the successful execution of an attack merely requires a user to interact with a malicious file. This makes it a potential vector for targeted attacks against unpatched systems.

How the Exploit Works
The exploit takes advantage of an Integer Underflow issue present in the affected Adobe Framemaker versions. Integer Underflow typically happens when an integer is used to specify the size of an object and the value of the integer falls below the minimum limit, causing it to wrap around to the maximum possible value. In this case, the exploit manipulates this issue to execute arbitrary code in the context of the current user.
The attacker delivers the exploit through a malicious file, which when opened, triggers the Integer Underflow vulnerability. As a result, the user unknowingly executes the attacker’s code, potentially compromising the system or leading to data leakage.
Conceptual Example Code
While there is no specific example code for this vulnerability, the following pseudocode illustrates the concept:
int size = user_input - CONSTANT_VALUE;
if (size < 0) {
size = MAX_INT; // Integer underflow resulting in wraparound
}
char *buffer = (char *) malloc(size);
read_file_into_buffer(user_file, buffer, size); // Buffer overflow
execute_code(buffer); // Arbitrary code executionThis conceptual code demonstrates how an Integer Underflow vulnerability can lead to a buffer overflow, further resulting in arbitrary code execution. In this context, a maliciously crafted user input or file could exploit the vulnerability.
