How to Fix CVE-2019-7617

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

elastic-apm fixed: 5.1.0 
pip install elastic-apm>=5.1.0
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 elastic-apm

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-7617, inspect your installed packages using pip:

pip show elastic-apm

Analyze the terminal output to locate any version of Elastic apm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.1.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Elastic apm, 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

When the Elastic APM agent for Python versions before 5.1.0 is run as a CGI script, there is a variable name clash flaw if a remote attacker can control the proxy header. This could result in an attacker redirecting collected APM data to a proxy of their choosing.
