CVE-2023-1802 : Vulnerability Insights and Analysis

This CVE-2023-1802 relates to a vulnerability in Docker Desktop version 4.17.x where the Artifactory Integration feature falls back to sending registry credentials over plain HTTP if the HTTPS health check has failed. This can potentially lead to a disclosure of sensitive information through a targeted network sniffing attack.

Understanding CVE-2023-1802

This section will delve into the essential aspects of CVE-2023-1802, shedding light on its nature, impact, technical details, affected systems, and mitigation strategies.

What is CVE-2023-1802?

CVE-2023-1802 is a vulnerability found in Docker Desktop 4.17.x, specifically within the Artifactory Integration feature. It occurs when registry credentials are transmitted over plain HTTP instead of HTTPS, making sensitive information vulnerable to network sniffing attacks.

The Impact of CVE-2023-1802

The impact of CVE-2023-1802 is categorized by the potential disclosure of confidential information due to the insecure transmission of registry credentials. This vulnerability is particularly concerning for users with the Access Experimental Features enabled and those logged into a private registry.

Technical Details of CVE-2023-1802

Exploring the technical specifics of CVE-2023-1802 provides a deeper understanding of how the vulnerability operates and its implications.

Vulnerability Description

In Docker Desktop 4.17.x, the Artifactory Integration feature exhibits a behavior where it sends registry credentials over plain HTTP if the HTTPS health check fails. This insecure transmission method can be exploited via network sniffing attacks.

Affected Systems and Versions

The vulnerability impacts Docker Desktop version 4.17.0 and earlier, specifically affecting users with Access Experimental Features enabled and logged into a private registry. The platforms affected include Windows, MacOS, and Linux.

Exploitation Mechanism

By exploiting the fallback behavior of Artifactory Integration to send registry credentials over unencrypted HTTP, malicious actors can intercept and sniff network traffic to obtain sensitive information.

Mitigation and Prevention

Addressing CVE-2023-1802 requires immediate action to mitigate the risk and prevent potential data breaches. Implementing effective security measures is crucial to safeguard systems and sensitive information.

Immediate Steps to Take

Users should update Docker Desktop to version 4.18.0 to patch the vulnerability and prevent further exploitation. Additionally, disabling the Access Experimental Features option from the settings panel can reduce the risk of exposure.

Long-Term Security Practices

In the long term, practicing secure data transmission protocols, regularly updating software to the latest versions, and monitoring network traffic for suspicious activities can enhance overall cybersecurity posture.

Patching and Updates

Regularly monitoring for software updates and promptly applying patches is essential to address known vulnerabilities like CVE-2023-1802. Keeping systems up to date ensures that the latest security improvements are in place to mitigate potential risks.
