CVE-2025-65471
Summary
CVE-2025-65471 is a high-severity vulnerability affecting EasyImages 2.0 versions up to 2.8.6. This vulnerability allows an attacker to upload arbitrary files to the server, potentially leading to arbitrary code execution and complete system compromise.
Technical Details
CVE-2025-65471 is an arbitrary file upload vulnerability located in the /admin/manager.php component of EasyImages 2.0. The application lacks sufficient validation of uploaded files, allowing an attacker to bypass security restrictions and upload malicious files, such as PHP scripts, to the server. When these uploaded files are accessed, the server executes the embedded code, granting the attacker control over the system. The vulnerability stems from inadequate input sanitization and a failure to properly restrict the types of files that can be uploaded. Specifically, the application does not adequately check the file extension or MIME type of uploaded files, allowing an attacker to disguise a malicious PHP script as a seemingly harmless file type. This bypass enables the attacker to execute arbitrary code within the context of the web server, potentially leading to data breaches, system compromise, and denial-of-service attacks. The vulnerability is exploitable by unauthenticated attackers who can access the vulnerable endpoint.
Affected Products and Versions
The following products and versions are affected by CVE-2025-65471:
- EasyImages 2.0 versions 2.8.6 and below
Impact Assessment
Successful exploitation of CVE-2025-65471 can have severe consequences, including:
- Arbitrary Code Execution: An attacker can execute arbitrary code on the server, potentially gaining complete control of the system.
- Data Breach: Sensitive data stored on the server could be accessed, modified, or deleted by the attacker.
- System Compromise: The entire system could be compromised, allowing the attacker to install malware, create backdoors, or launch further attacks.
- Denial of Service: The attacker could disrupt the availability of the application by overloading the server or causing it to crash.
Remediation
To mitigate the risk posed by CVE-2025-65471, the following actions are recommended:
Immediate Actions
- Upgrade EasyImages: Upgrade to a patched version of EasyImages that addresses the vulnerability. If a patch is not yet available, monitor the vendor's website for updates.
- Restrict Access: Limit access to the
/admin/manager.phpcomponent to only authorized users. - Implement File Validation: Implement robust file validation on the server-side to prevent the upload of malicious files. This should include checking the file extension, MIME type, and file content.
Long-term Solutions
- Input Sanitization: Implement proper input sanitization and validation throughout the application to prevent various types of attacks.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests.
