CVE-2025-22884: Buffer Overflow Vulnerability in Delta Electronics ISPSoft

Overview

In this post, we will discuss a significant vulnerability, CVE-2025-22884, identified in Delta Electronics ISPSoft version 3.20. This vulnerability is a stack-based buffer overflow that can potentially allow an attacker to execute arbitrary code when parsing a DVP file. This vulnerability affects all systems running this version of ISPSoft and poses a significant threat due to the potential for system compromise and data leakage.
The importance of addressing this vulnerability cannot be overstated. Given the widespread use of Delta Electronics ISPSoft in various industries, this vulnerability could have far-reaching consequences. It is crucial to understand this vulnerability and implement mitigation strategies promptly.

How the Exploit Works

The exploit works by taking advantage of a stack-based buffer overflow vulnerability in ISPSoft. An attacker can craft a malicious DVP file which, when parsed by the software, allows the attacker to overflow the buffer. This overflow can then be used to inject and execute arbitrary code. The executed code can give the attacker control over the system or allow them to exfiltrate sensitive data.

Conceptual Example Code

Here is a conceptual example of how this vulnerability might be exploited. Note that this is a simplified representation and actual exploitation may require more advanced techniques.

# This is pseudocode for a malicious DVP file
# Normal data
data = "Normal DVP file content..."
# Buffer overflow
overflow = "A" * 1024
# Arbitrary code to be executed
code = "malicious code..."
# Craft malicious DVP file
malicious_file = data + overflow + code
# Save the file
with open('malicious.dvp', 'w') as f:
f.write(malicious_file)

This malicious DVP file could then be used to exploit the vulnerability in ISPSoft. When the software attempts to parse the file, it would trigger the buffer overflow and execute the arbitrary code.

Mitigation

To mitigate this vulnerability, users should apply the vendor patch as soon as possible. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. These tools can detect and block attempts to exploit this vulnerability. However, they should not be considered a long-term solution, and the vendor patch should be applied as soon as it is available.
