CVE-2024-41114

Comprehensive Technical Analysis of CVE-2024-41114

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-41114

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 430 takes user input, which is later used in the eval() function on line 435. 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 is a classic example of a code injection vulnerability, which can allow an attacker to execute arbitrary code on the server.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can craft a malicious input for the palette variable, which will be executed by the eval() function. This can lead to arbitrary code execution on the server.
• Data Exfiltration: An attacker could use the RCE to exfiltrate sensitive data from the server.
• Denial of Service (DoS): An attacker could use the RCE to execute commands that disrupt the normal operation of the server.

Exploitation Methods:

• Direct Input Manipulation: An attacker can directly manipulate the input to the palette variable to inject malicious code.
• Cross-Site Scripting (XSS): If the application is web-based, an attacker could use XSS to inject malicious scripts that manipulate the palette variable.

3. Affected Systems and Software Versions

Affected Systems:

• Any system running the streamlit-geospatial application prior to the commit c4f81d9616d40c60584e36abb15300853a66e489.

Software Versions:

• All versions of streamlit-geospatial before the fix commit c4f81d9616d40c60584e36abb15300853a66e489.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Software: Ensure that all instances of streamlit-geospatial are updated to the version that includes the fix commit c4f81d9616d40c60584e36abb15300853a66e489.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially those used in dynamic code execution functions like eval().
• Disable eval(): Avoid using the eval() function for executing user-provided input. Use safer alternatives like predefined functions or libraries.

Long-Term Strategies:

• Code Review: Conduct thorough code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Provide security training for developers to educate them on 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:

• Increased Risk: Organizations using the affected versions of streamlit-geospatial are at high risk of RCE attacks, which can lead to data breaches, service disruptions, and other security incidents.
• Reputation Damage: Organizations experiencing a breach due to this vulnerability may face reputational damage and loss of customer trust.

Long-Term Impact:

• Enhanced Awareness: This vulnerability highlights the importance of secure coding practices and the risks associated with using dynamic code execution functions.
• Improved Security Practices: The incident may lead to improved security practices and more rigorous code reviews in the development community.

6. Technical Details for Security Professionals

Vulnerable Code:

# pages/1_📷_Timelapse.py
palette = user_input  # Line 430
eval(palette)  # Line 435

Fixed Code:

# pages/1_📷_Timelapse.py
palette = sanitize_input(user_input)  # Line 430
safe_execute(palette)  # Line 435

Sanitization Function Example:

def sanitize_input(input_str):
    # Implement a robust sanitization logic here
    return input_str.replace(';', '').replace('`', '').replace('|', '')

def safe_execute(input_str):
    # Implement a safe execution logic here
    pass
