Overview
A significant security vulnerability, identified as CVE-2025-54215, has been detected in Adobe’s InCopy software. This vulnerability affects versions 20.4, 19.5.4, and earlier. It is an out-of-bounds write vulnerability, which could lead to arbitrary code execution in the context of the current user. The exploit of this vulnerability requires user interaction, such as opening a malicious file. This vulnerability poses a considerable risk to businesses and users who utilize Adobe’s InCopy software, as it could potentially lead to system compromise or data leakage.

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.icmlThe 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.
