How the Exploit Works

The exploitation of CVE-2025-54221 involves the abuse of an out-of-bounds write vulnerability in InCopy. This vulnerability allows an attacker to write data outside the expected boundaries of allocated memory, potentially leading to the execution of arbitrary code. The exploit requires user interaction, specifically the victim must open a malicious file. Once the file is opened, the attacker can execute code in the context of the current user, potentially gaining unauthorized access or causing data leakage.

Conceptual Example Code

While the exact code to exploit this vulnerability could vary depending on the specific target, an example of how this might look is as follows:

# Attacker prepares a malicious InCopy file
echo "malicious_payload" > malicious.icml
# Attacker sends the malicious file to the victim
mail -s "Important Document" victim@example.com < malicious.icml

In this example, the attacker creates a malicious InCopy file and sends it to the victim via email. If the victim opens this malicious file with a vulnerable version of InCopy, the arbitrary code embedded within the file would be executed, potentially compromising the system or causing data leakage.

Mitigation Guidance

To mitigate the risk posed by CVE-2025-54221, users should apply the vendor-provided patch as soon as it is available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and potentially block exploitation attempts. Regularly updating and patching software is one of the most effective ways to protect against such vulnerabilities.

Vulnerability Summary

CVE ID: CVE-2025-54220
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: System Compromise or Data Leakage

Affected Products

Product | Affected Versions

InCopy | 20.4
InCopy | 19.5.4 and earlier

How the Exploit Works

The exploit takes advantage of a heap-based buffer overflow vulnerability in the InCopy software. In this case, an attacker could craft a malicious file that, when opened in the affected versions of InCopy, overflows the buffer and corrupts the heap memory. This could allow the attacker to execute arbitrary code in the context of the current user. The attacker’s code could potentially take full control of the affected system, leading to a system compromise, or access sensitive data, resulting in data leakage.

Conceptual Example Code

Below is a conceptual example demonstrating how an attacker might craft a malicious file to exploit this vulnerability:

#include <stdio.h>
#include <string.h>
#define BUFFER_SIZE 100
int main() {
char buffer[BUFFER_SIZE];
FILE *malicious_file;
malicious_file = fopen("malicious_file.icml", "r");
if (malicious_file == NULL) {
printf("Could not open file\n");
return 1;
}
fread(buffer, BUFFER_SIZE, 1, malicious_file);
buffer[BUFFER_SIZE - 1] = '\0';
fclose(malicious_file);
}

In the above example, the buffer size is defined as 100 bytes. If the content of the `malicious_file.icml` is larger than 100 bytes, it will overflow the buffer and corrupt the heap memory, possibly leading to arbitrary code execution.
Please note that this is a simplified and conceptual example. Actual exploits would be more complex and require a deeper understanding of the software’s internal workings.

Overview

Vulnerability Summary

CVE ID: CVE-2025-54219
Severity: High (CVSS: 7.8)
Attack Vector: Local File
Privileges Required: None
User Interaction: Required
Impact: Arbitrary code execution leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

InCopy | 20.4, 19.5.4 and earlier versions

How the Exploit Works

This exploit takes advantage of a Heap-based Buffer Overflow vulnerability in InCopy. When a specially crafted malicious file is opened by the victim, the vulnerability is triggered, allowing an attacker to overflow the buffer and consequently execute arbitrary code. This code execution occurs in the context of the current user, potentially giving the attacker the same permissions as the victim.

Conceptual Example Code

While the specifics of the exploit are not publicly available, a conceptual example of how the vulnerability might work is as follows:

def exploit(file):
# Open the file
with open(file, 'rb') as f:
# Read the file data
data = f.read()
# Craft a malicious payload that overflows the buffer
payload = b'\x90' * 1024 + b'\xcc' * 4
# Replace a specific portion of the file data with the payload
exploit_data = data.replace(b'\x00'*1024, payload)
# Write the exploit data back to the file
with open(file, 'wb') as f:
f.write(exploit_data)

This is a simplified conceptual example. The actual exploit would likely involve more complex manipulation of the file data to trigger the buffer overflow and execute the desired code.

Mitigation Guidance

Users are strongly advised to apply the vendor patch as soon as it is available. In the meantime, using Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regularly backing up data and maintaining good cybersecurity hygiene, such as not opening files from unknown sources, can also help protect against potential attacks.

How the Exploit Works

The root cause of this vulnerability lies in an out-of-bounds write error in the affected versions of InCopy software. This error can be exploited by a malicious actor to execute arbitrary code in the context of the current user. Exploitation, however, requires user interaction, such as opening a maliciously crafted file. Once this file is opened, the out-of-bounds write vulnerability can be triggered, allowing the attacker to potentially take control of the system or cause data leakage.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited is by creating a malicious InCopy file that triggers the out-of-bounds write when it is opened by the victim. Here is a simplified pseudocode representation of how this might occur:

// Malicious InCopy file
Create InCopy file with out-of-bounds data
Write malicious code in out-of-bounds area
// User's system
User opens malicious InCopy file
InCopy attempts to read out-of-bounds data
Out-of-bounds write triggers
Execution control shifts to malicious code

This example is highly simplified and conceptual, but it serves to illustrate the core mechanics of the exploit.

Mitigation

Users are strongly advised to apply the vendor-supplied patch to fix this vulnerability as soon as possible. As a temporary mitigation, users may employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS). However, these measures only serve to reduce the risk and do not fully eliminate the vulnerability. Therefore, the application of the vendor patch should not be delayed.

How the Exploit Works

The exploit takes advantage of an out-of-bounds write vulnerability in InCopy. This kind of vulnerability occurs when the software writes data outside the boundaries of intended memory buffers. By doing so, the attacker can manipulate the application’s execution flow or even execute arbitrary code. In this case, the attacker crafts a malicious file that triggers the vulnerability when opened by the user in the affected InCopy versions. This can lead to arbitrary code execution in the context of the current user, potentially compromising the system or leading to data leakage.

Conceptual Example Code

Given the nature of the vulnerability, an example exploit might involve crafting a malicious InCopy file with out-of-bounds data. The below pseudocode conceptualizes this:

var malicious_file = new InCopyFile();
malicious_file.insertData("normal data");
malicious_file.insertDataOutOfBound("malicious code");
malicious_file.save("malicious.icml");

In this pseudocode, the attacker creates a new InCopy file (`malicious_file`), inserts normal data, and then inserts malicious code outside the intended memory bounds. The `insertDataOutOfBound` function is representative of the attacker’s manipulation of the file to exploit the vulnerability. The malicious file is then saved and can be distributed to potential victims.

Impact: Arbitrary code execution, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

Adobe InCopy | 20.4 and earlier
Adobe InCopy | 19.5.4 and earlier

How the Exploit Works

The out-of-bounds write vulnerability is triggered when a user opens a specifically crafted malicious file using Adobe’s InCopy software. This allows an attacker to write data beyond the memory allocation. The software fails to properly handle this anomaly, leading to an unexpected state. As a result, it could allow an attacker to execute arbitrary code in the context of the current user, leading potentially to system compromise or data leakage.

Conceptual Example Code

Here is a hypothetical example of how the vulnerability might be exploited. The attacker creates a malicious file with an overflow of data that will be written out-of-bounds when opened in Adobe’s InCopy software:

$ echo -n "malicious_payload" > exploit.icml
$ zip exploit.zip exploit.icml

The attacker then convinces a user to open the `exploit.zip` file in their vulnerable Adobe InCopy software, which triggers the overflow and potentially allows the attacker to execute arbitrary code. For safety reasons, the details of how the malicious payload might work are not provided.
Please note that this is a conceptual example and might not represent the actual exploit.
