CVE ID: CVE-2024-30247 CVSS Score: 10

The vulnerability in NextCloudPi, a ready-to-use image for various hardware platforms, involves a command injection flaw that allows unauthenticated command execution as the root user via the NextCloudPi web-panel. This vulnerability is rated with a CVSS score of 10, indicating a critical severity due to the potential for complete system compromise without requiring any authentication.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited by anyone with access to the NextCloudPi web-panel, as no authentication is required.
• Command Injection: An attacker can inject arbitrary commands through the web-panel, which are executed with root privileges.

Exploitation Methods:

• Direct Command Execution: An attacker can input malicious commands directly into the web-panel, leading to arbitrary code execution.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable NextCloudPi instances and exploit them en masse.

3. Affected Systems and Software Versions

Affected Systems:

• NextCloudPi versions prior to 1.53.1

Hardware Platforms:

• Virtual Machines
• Raspberry Pi
• Odroid HC1
• Rock64
• Other compatible boards

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Upgrade NextCloudPi to version 1.53.1 or later, which includes the security patch for this vulnerability.
• Access Control: Restrict access to the NextCloudPi web-panel to trusted IP addresses and implement strong authentication mechanisms.
• Network Segmentation: Isolate NextCloudPi instances from public networks and limit access to internal networks only.

Long-Term Strategies:

• Regular Patching: Implement a regular patching and update schedule for all software components.
• Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential security issues.
• Intrusion Detection: Deploy intrusion detection systems (IDS) to monitor for suspicious activities and potential exploitation attempts.
