How to Fix CVE-2024-37155

To remediate this vulnerability, upgrade all affected Pycti dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pycti fixed: 6.1.9 
pip install pycti>=6.1.9
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show pycti

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-37155, inspect your installed packages using pip:

pip show pycti

Analyze the terminal output to locate any version of Pycti in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.1.9), your application is affected.

Note: The pip show pycti command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Pycti, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The regex validation used to prevent Introspection queries can be bypassed by removing the extra whitespace, carriage return, and line feed characters from the query. ### Details GraphQL Queries in OpenCTI can be validated using the `secureIntrospectionPlugin`. ### Impact Bypassing this restriction allows the attacker to gather a wealth of information about the GraphQL endpoint functionality that can be used to perform actions and/or read data without authorization. These queries can also be weaponized to conduct a Denial of Service (DoS) attack if sent repeatedly.
