CVE-2024-41115

Comprehensive Technical Analysis of CVE-2024-41115

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-41115

Description: The vulnerability exists in the streamlit-geospatial application, specifically in the pages/1_📷_Timelapse.py file. Prior to commit c4f81d9616d40c60584e36abb15300853a66e489, the palette variable on line 488 takes user input, which is later used in the eval() function on line 493. This leads to a remote code execution (RCE) vulnerability.

CVSS Score: 9.8

Severity Evaluation:

• Critical: A CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for remote code execution, which can lead to complete system compromise.
• Impact: The vulnerability allows an attacker to execute arbitrary code on the affected system, potentially leading to data breaches, system takeovers, and further malicious activities.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• User Input Manipulation: An attacker can manipulate the palette variable input to inject malicious code.
• Remote Code Execution: The eval() function executes the injected code, allowing the attacker to run arbitrary commands on the server.

Exploitation Methods:

• Code Injection: The attacker can inject Python code into the palette variable, which will be executed by the eval() function.
• Command Execution: The injected code can include system commands, leading to further exploitation of the server.

3. Affected Systems and Software Versions

Affected Systems:

• Any system running the streamlit-geospatial application with the vulnerable code.

Software Versions:

• Versions of streamlit-geospatial prior to the commit c4f81d9616d40c60584e36abb15300853a66e489.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Software: Ensure that the streamlit-geospatial application is updated to include the fix provided in commit c4f81d9616d40c60584e36abb15300853a66e489.
• Input Validation: Implement strict input validation to sanitize user inputs and prevent code injection.
• Avoid eval(): Refactor the code to avoid using the eval() function, which is inherently risky.

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 include the latest security patches.

5. Impact on Cybersecurity Landscape

Broader Implications:

• Supply Chain Security: This vulnerability highlights the importance of securing open-source software and dependencies, as they are often integrated into larger systems.
• Code Quality: Emphasizes the need for rigorous code reviews and secure coding practices to prevent such vulnerabilities.
• Incident Response: Organizations should have robust incident response plans to quickly address and mitigate critical vulnerabilities.

6. Technical Details for Security Professionals

Vulnerable Code Snippet:

# pages/1_📷_Timelapse.py
palette = user_input  # Line 488
eval(palette)  # Line 493

Fixed Code Snippet:

# pages/1_📷_Timelapse.py
palette = sanitize_input(user_input)  # Line 488
# Avoid using eval()

Sanitization Function Example:

def sanitize_input(input_str):
    # Implement strict validation and sanitization logic
    # Example: Allow only alphanumeric characters and specific symbols
    return re.sub(r'[^a-zA-Z0-9_]', '', input_str)
