How to Fix CVE-2014-3243

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

SOAPpy fixed: 0.12.6 
pip install SOAPpy>=0.12.6
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 SOAPpy

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2014-3243, inspect your installed packages using pip:

pip show SOAPpy

Analyze the terminal output to locate any version of SOAPpy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.6), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In SOAPpy, 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

SOAPpy 0.12.5 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted SOAP request containing a large number of nested entity references.
