CVE-2024-41116

Comprehensive Technical Analysis of CVE-2024-41116

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-41116

Description: The vulnerability exists in the streamlit-geospatial application, specifically in the pages/1_📷_Timelapse.py file. Prior to commit c4f81d9616d40c60584e36abb15300853a66e489, the vis_params variable on line 1254 takes user input, which is later used in the eval() function on line 1345. This leads to remote code execution (RCE).

CVSS Score: 9.8

Severity: Critical

The high CVSS score of 9.8 indicates that this vulnerability is extremely severe. The use of the eval() function with user input allows for arbitrary code execution, which can be exploited to gain full control over the affected system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can inject malicious code through the vis_params variable, which is then executed by the eval() function.
• Cross-Site Scripting (XSS): If the input is not properly sanitized, an attacker could inject malicious scripts that execute in the context of the user's browser.

Exploitation Methods:

• Direct Code Injection: An attacker can craft a payload that includes malicious Python code, which will be executed by the eval() function.
• Chained Exploits: Combining this vulnerability with other weaknesses in the application could lead to more sophisticated attacks, such as privilege escalation or data exfiltration.

3. Affected Systems and Software Versions

Affected Software:

• streamlit-geospatial multipage app for geospatial applications.

Affected Versions:

• All versions prior to the commit c4f81d9616d40c60584e36abb15300853a66e489.

Systems:

• Any system running the vulnerable version of the streamlit-geospatial application.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update to the Latest Version: Ensure that the streamlit-geospatial application is updated to include the fix provided in commit c4f81d9616d40c60584e36abb15300853a66e489.
• Input Validation: Implement strict input validation and sanitization for all user inputs to prevent malicious code injection.
• Avoid eval(): Refrain from using the eval() function for executing user-provided input. Use safer alternatives like ast.literal_eval() for evaluating literals.

Long-Term Strategies:

• Code Review: Conduct thorough code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Educate developers on secure coding practices and the risks associated with using functions like eval().
• Regular Updates: Ensure that all software dependencies are regularly updated to their latest versions.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• High Risk of Exploitation: Given the critical nature of the vulnerability, there is a high risk of exploitation in the wild.
• Data Breaches: Successful exploitation could lead to data breaches, unauthorized access, and potential data loss.

Long-Term Impact:

• Increased Awareness: This vulnerability highlights the importance of secure coding practices and the risks associated with using functions like eval().
• Enhanced Security Measures: Organizations may implement stricter input validation and code review processes to prevent similar vulnerabilities in the future.

6. Technical Details for Security Professionals

Vulnerable Code Snippet:

# pages/1_📷_Timelapse.py
vis_params = user_input  # Line 1254
eval(vis_params)  # Line 1345

Fixed Code Snippet:

# pages/1_📷_Timelapse.py
vis_params = user_input  # Line 1254
# Safe alternative to eval()
import ast
safe_params = ast.literal_eval(vis_params)  # Line 1345

Exploitation Example: An attacker could inject a payload like:

__import__('os').system('rm -rf /')

This payload, if executed, would delete all files on the system.

Detection and Monitoring:

• Logging: Implement logging to monitor and detect any suspicious activities related to the eval() function.
• Intrusion Detection Systems (IDS): Use IDS to detect and alert on any unusual patterns or behaviors that may indicate an exploitation attempt.

Conclusion: CVE-2024-41116 is a critical vulnerability that underscores the importance of secure coding practices and input validation. Organizations should prioritize updating to the patched version and implementing robust security measures to mitigate the risk of exploitation.
