CVE-2025-27813: Missing PE Signature Validation in MSI Center

Overview

CVE-2025-27813 is a significant vulnerability discovered in MSI Center before version 2.0.52.0. This vulnerability, characterized by the missing PE (Portable Executable) Signature Validation, can lead to potential system compromise and data leakage. The flaw primarily affects users of the MSI Center software and is of notable concern due to its high severity rating of 8.1 on the CVSS scale. It is crucial for users and organizations using affected versions to understand and mitigate this vulnerability to protect their systems and data.

How the Exploit Works

The vulnerability arises from the lack of PE Signature Validation in MSI Center before version 2.0.52.0. This vulnerability could allow an attacker to deliver a malicious payload through the MSI Center software by masking it as a legitimate PE file. Without proper validation, the system cannot differentiate between legitimate and malicious files, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example demonstrating how this vulnerability might be exploited using a malicious payload:

# Attacker crafts a malicious PE file
echo '...malicious code...' > malicious.pe
# Attacker transfers the malicious PE file to the target system
scp malicious.pe user@target:/path/to/MSI_Center
# Attacker tricks the user into executing the malicious PE file within the MSI Center context
echo 'Please run this important update: /path/to/MSI_Center/malicious.pe' | mail -s 'Important Update' user@target

In the above conceptual example, the attacker first crafts a malicious PE file and transfers it to the target system. They then trick the user into executing the malicious file within the MSI Center context. If successful, this exploit could lead to system compromise or data leakage.

Recommended Mitigation

Users are advised to update their MSI Center software to version 2.0.52.0 or later to address this vulnerability. For temporary mitigation, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can help detect and prevent potential exploits. However, these are not full-proof solutions, and updating the software remains the most effective mitigation method.
