How to Fix CVE-2008-0252

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

cherrypy fixed: 2.1.1 
pip install cherrypy>=2.1.1
cherrypy fixed: 3.0.2 
pip install cherrypy>=3.0.2
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 cherrypy

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2008-0252, inspect your installed packages using pip:

pip show cherrypy

Analyze the terminal output to locate any version of Cherrypy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Cherrypy, 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

Directory traversal vulnerability in the _get_file_path function in (1) `lib/sessions.py` in CherryPy 3.0.x up to 3.0.2, (2) `filter/sessionfilter.py` in CherryPy 2.1, and (3) `filter/sessionfilter.py` in CherryPy 2.x allows remote attackers to create or delete arbitrary files, and possibly read and write portions of arbitrary files, via a crafted session id in a cookie.
