CVE-ID: CVE-2025-55835

Affected Software: SueamCMS Multiple Products

Affected Versions: Version 0.1.2 is confirmed to be vulnerable. See vendor advisory for a complete list of affected products and versions.

Vulnerability: The vulnerability is an unrestricted file upload due to a lack of proper filtering on file types and content. An attacker can craft a malicious file, such as a web shell (e.g., a .php file), and upload it to the server through a legitimate file upload function. Because the application fails to validate that the uploaded file is of an expected type (like an image), the malicious file is saved to the server. The attacker can then navigate to the location of the uploaded file, causing the server to execute the code within it, granting the attacker remote code execution capabilities with the privileges of the web server process.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Successful exploitation could lead to a complete compromise of the affected web server. The potential consequences include theft of sensitive data (such as customer information, intellectual property, or credentials), website defacement, service interruption, and significant reputational damage. Furthermore, a compromised server can be used as a pivot point to launch further attacks against other systems within the organization's internal network, escalating the overall risk.

Remediation Plan

Immediate Action: Immediately apply the security update provided by the vendor to patch all instances of SueamCMS Multiple Products to the latest version. Prioritize patching for systems that are exposed to the internet.
