The vulnerability in question is a "zip slip" vulnerability affecting the /DesignTools/SkinList.aspx endpoint of MojoPortal CMS version 2.9.0.1. This type of vulnerability allows attackers to execute arbitrary commands by uploading a specially crafted zip file. The CVSS score of 10 indicates that this vulnerability is critical, posing a significant risk to affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• File Upload: The primary attack vector involves uploading a maliciously crafted zip file to the vulnerable endpoint.
• Command Execution: Once the zip file is uploaded and extracted, the attacker can execute arbitrary commands on the server.

Exploitation Methods:

• Crafted Zip File: An attacker can create a zip file with a directory traversal payload that, when extracted, writes files to arbitrary locations on the server.
• Command Injection: By placing executable scripts or commands within the zip file, the attacker can achieve remote code execution (RCE).

3. Affected Systems and Software Versions

Affected Software:

• MojoPortal CMS version 2.9.0.1

Affected Systems:

• Any server running MojoPortal CMS version 2.9.0.1 with the /DesignTools/SkinList.aspx endpoint exposed.
