CVE-2025-65473: CRITICAL Severity Vulnerability | Secably CVE Database

Summary

CVE-2025-65473 is a critical severity vulnerability affecting EasyImages 2.0 versions 2.8.6 and below. This vulnerability allows an authenticated attacker with administrator privileges to execute arbitrary code on the server by injecting a malicious payload into the filename of an uploaded file, which is then processed by the /admin/filer.php component due to an arbitrary file rename vulnerability.

Technical Details

The vulnerability resides in the /admin/filer.php component of EasyImages 2.0. The application fails to properly sanitize or validate the filename of uploaded files. An attacker with administrator privileges can craft a malicious filename containing code (e.g., PHP code) and upload it through the application's file upload functionality. When the application attempts to rename the file, the injected code is executed by the server. This is because the application uses the provided filename directly in a system call without proper escaping or sanitization. The arbitrary file rename vulnerability allows for remote code execution (RCE) on the server.

The vulnerability is triggered during the file rename operation within the /admin/filer.php script. The attacker leverages the ability to control the filename to inject malicious code that gets executed when the server attempts to rename the uploaded file. This execution occurs with the privileges of the web server user, potentially leading to full system compromise.

Impact Assessment

Successful exploitation of CVE-2025-65473 can have severe consequences, including:

Remote Code Execution (RCE): An attacker can execute arbitrary code on the server, potentially gaining complete control of the system.
Data Breach: An attacker can access sensitive data stored on the server, including user credentials, configuration files, and other confidential information.
System Compromise: An attacker can compromise the entire system, leading to denial of service, data corruption, and other malicious activities.
Website Defacement: An attacker can modify the website's content, causing reputational damage.

Remediation

To mitigate the risk posed by CVE-2025-65473, the following actions are recommended:

Immediate Actions

Upgrade EasyImages 2.0: Upgrade to a patched version of EasyImages 2.0 that addresses this vulnerability. If a patch is not available, consider discontinuing use of the affected software.
Restrict Access: Limit access to the /admin/filer.php component to only authorized administrators.
Input Validation: Implement strict input validation and sanitization for all user-supplied data, especially filenames, to prevent code injection.

Long-term Solutions

Code Review: Conduct a thorough code review of the EasyImages 2.0 codebase to identify and fix other potential vulnerabilities.
Web Application Firewall (WAF): Deploy a web application firewall (WAF) to detect and block malicious requests targeting the vulnerability.
Regular Security Audits: Perform regular security audits and penetration testing to identify and address vulnerabilities proactively.
