CVE-2025-65474: CRITICAL Severity Vulnerability | Secably CVE Database

Summary

CVE-2025-65474 is a critical severity vulnerability affecting EasyImages 2.0 versions 2.8.6 and below. It allows an attacker to execute arbitrary code on the server by exploiting an arbitrary file rename vulnerability in the /admin/manager.php component. This is achieved by renaming a PHP file to an SVG format, bypassing security checks and enabling code execution.

Technical Details

The vulnerability lies within the file management functionality of the /admin/manager.php component of EasyImages 2.0. The application lacks proper validation and sanitization when renaming files. An attacker can leverage this flaw to rename a PHP file (e.g., shell.php) to an SVG file (e.g., shell.svg). Due to misconfiguration or insufficient server-side checks, the server may then execute the renamed SVG file as PHP code, leading to arbitrary code execution. This is because the server might be configured to interpret SVG files as PHP if they contain PHP code within them, or if the server's MIME type handling is flawed. The attacker can then upload a PHP file containing malicious code, rename it to an SVG, and trigger its execution by accessing the renamed file through a web browser.

The root cause is insufficient input validation and lack of proper file type verification during the file rename process. The application fails to prevent the renaming of executable files to other executable extensions, leading to a bypass of security measures intended to prevent unauthorized code execution.

Impact Assessment

Successful exploitation of CVE-2025-65474 can lead to complete compromise of the affected server. An attacker can gain full control over the system, allowing them to:

Execute arbitrary code, potentially installing malware or creating backdoors.
Access sensitive data, including user credentials, database information, and configuration files.
Modify or delete critical system files, leading to denial of service.
Pivot to other systems on the network, potentially compromising the entire infrastructure.

Remediation

Immediate Actions

Upgrade EasyImages 2.0: Upgrade to a patched version of EasyImages 2.0 that addresses this vulnerability. Check the vendor's website for updates. If no patch is available, consider discontinuing use of the software.
Implement File Type Validation: Implement strict file type validation on the server-side to prevent renaming of PHP files to other executable extensions. Use a whitelist approach, only allowing specific file types to be uploaded and renamed.
Disable PHP Execution in Upload Directories: Configure the web server to prevent PHP execution in the upload directory. This can be achieved by adding a .htaccess file with the following content: <Files *.*> deny from all </Files>.

Long-term Solutions

Code Review: Conduct a thorough code review of the EasyImages 2.0 codebase to identify and fix other potential vulnerabilities.
Security Audits: Regularly perform security audits and penetration testing to identify and address security weaknesses.
Web Application Firewall (WAF): Implement a Web Application Firewall (WAF) to detect and block malicious requests targeting this and other vulnerabilities.
