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.

Vulnerability Summary

CVE ID: CVE-2025-47128
Severity: High, CVSS Score 7.8

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 execution

This 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.

Overview

CVE-2025-47127 is a significant vulnerability discovered in Adobe Framemaker versions 2020.8, 2022.6, and earlier. This out-of-bounds write vulnerability could potentially lead to arbitrary code execution, allowing malicious actors to execute arbitrary commands in the context of the current user. The vulnerability is particularly concerning as Adobe Framemaker is widely used for writing and editing large documents, making many users potentially susceptible to this threat.
Given the severity of this vulnerability, it is crucial for users and organizations to understand its implications. A successful exploit could result in system compromise or data leakage, leading to potentially significant business and operational impacts.

How the Exploit Works

The exploit takes advantage of an out-of-bounds write vulnerability in Adobe Framemaker. The vulnerability is triggered when a user opens a malicious file, allowing an attacker to write data outside of the allocated memory bounds. This can lead to a buffer overflow, causing the application to crash or, more dangerously, allowing the attacker to execute arbitrary code in the context of the current user.

Conceptual Example Code

The following pseudocode example illustrates how a malicious file might exploit the vulnerability:

def exploit(file):
buffer = create_buffer(file)
if len(buffer) > allocated_memory:
overflow = len(buffer) - allocated_memory
write_data_to_memory(buffer, overflow)
execute_arbitrary_code()

This pseudocode is a conceptual example showing how a buffer overflow could be used to write data outside the allocated memory bounds and execute arbitrary code. The precise details of exploiting this vulnerability in a real-world scenario would depend on many factors, including the specific implementation of Adobe Framemaker and the system it is running on.

Mitigation Guidance

Users are advised to apply the vendor patch as soon as it becomes available. In the meantime, Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can be used as temporary mitigation measures. They can be configured to detect and block the types of malicious files that could exploit this vulnerability, reducing the risk of arbitrary code execution.

Overview

The Common Vulnerabilities and Exposures (CVE) system has announced CVE-2025-47126, a critical vulnerability found in Adobe Framemaker versions 2020.8, 2022.6, and earlier. This vulnerability, an out-of-bounds write vulnerability, could potentially allow an attacker to execute arbitrary code in the context of the current user. This exploit requires user interaction, as a victim must open a malicious file for the vulnerability to be exploited. It poses a significant threat to users and businesses alike, particularly those who heavily rely on Adobe Framemaker for their daily operations. This vulnerability is of critical concern due to its potential to lead to a system compromise or data leakage.

How the Exploit Works

The vulnerability, an out-of-bounds write error, originates from the failure of Adobe Framemaker to properly verify user-supplied data before copying it to an insufficiently sized memory buffer. This allows an attacker to deliver a malicious file, which when opened by a user, would overflow the buffer and overwrite adjacent memory spaces. This memory corruption could then be leveraged by the attacker to execute arbitrary code in the context of the current user, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example that demonstrates how the vulnerability might be exploited. This pseudocode represents a malicious file that triggers the out-of-bounds write:

def malicious_file():
# Create an overly large buffer
buffer = "A" * 50000
# Write the buffer to a file
with open("malicious.fmk", "w") as file:
file.write(buffer)
malicious_file()

In this simplified example, the attacker creates a ‘malicious.fmk’ file with an overly large buffer, and if a user opens this file with a vulnerable version of Adobe Framemaker, it would trigger the out-of-bounds write, potentially leading to arbitrary code execution.
Remember that this is a conceptual example and not a real exploit. Actual exploitation would likely involve the use of specific techniques to control the execution flow of the vulnerable application.
