CVE-2023-4760 : What You Need to Know

This CVE-2023-4760 article provides detailed information about a critical vulnerability affecting Eclipse RAP on Windows, leading to Remote Code Execution.

Understanding CVE-2023-4760

This section delves into the specifics of the CVE-2023-4760 vulnerability, outlining its impact, technical details, affected systems, and mitigation strategies.

What is CVE-2023-4760?

CVE-2023-4760 involves Remote Code Execution in Eclipse RAP versions ranging from 3.0.0 to 3.25.0 on Windows. The vulnerability arises due to insecure handling of file names in the FileUpload component, allowing malicious actors to execute arbitrary code.

The Impact of CVE-2023-4760

The impact of CVE-2023-4760 is significant, as it permits attackers to upload and execute malicious files on Windows systems using Eclipse RAP, potentially leading to unauthorized access, data compromise, or system manipulation.

Technical Details of CVE-2023-4760

This section provides a deeper insight into the technical aspects of the CVE-2023-4760 vulnerability.

Vulnerability Description

The vulnerability stems from a flaw in the FileUploadProcessor.stripFileName(String name) method of Eclipse RAP. Improper extraction of file names allows for path traversal, enabling attackers to upload and execute files by manipulating backslashes in file paths.

Affected Systems and Versions

Eclipse RAP versions from 3.0.0 to 3.25.0 running on Windows platforms are susceptible to this vulnerability, exposing them to the risk of Remote Code Execution.

Exploitation Mechanism

By crafting malicious file names containing path traversal sequences like /..\..\, attackers can bypass security controls and upload files to compromise Windows systems running vulnerable versions of Eclipse RAP.

Mitigation and Prevention

To safeguard systems from CVE-2023-4760, prompt actions and security measures are essential.

Immediate Steps to Take

Organizations using affected versions should apply security patches promptly.
Implement network-level security controls to monitor and restrict file uploads.
Educate users on safe file uploading practices to mitigate risks.

Long-Term Security Practices

Regularly update software and apply security patches to prevent known vulnerabilities.
Conduct security audits and penetration testing to identify and address potential weaknesses.
Implement secure coding practices and review file upload mechanisms for vulnerabilities.

Patching and Updates

Users of Eclipse RAP versions 3.0.0 to 3.25.0 on Windows should update to a patched version to mitigate the risk of Remote Code Execution. Patching is crucial to ensure the security and integrity of systems and data.

By addressing CVE-2023-4760 through timely updates and proactive security measures, organizations can enhance their resilience against potential cyber threats and unauthorized access.
