How to Fix CVE-2018-10917

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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

pulpcore fixed: Latest secure release 
pip install pulpcore>=Latest secure release
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 pulpcore

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2018-10917, inspect your installed packages using pip:

pip show pulpcore

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree.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

Note: The pip show pulpcore 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 In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

## Withdrawn Advisory This advisory has been withdrawn because the package [pulpcore](https://pypi.org/project/pulpcore/) deals with pulp 3 only. This advisory concerns [pulp 2](https://github.com/pulp/pulp), which is not in a [supported ecosystem](https://github.com/github/advisory-database/blob/main/README.md#supported-ecosystems). ## Original Description pulp 2.16.x and possibly older is vulnerable to an improper path parsing. A malicious user or a malicious iso feed repository can write to locations accessible to the 'apache' user. This may lead to overwrite of published content on other iso repositories.
