Vulnerability from pysec

Details

OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service interface standards, and their related content models. OWSLib's XML parser (which supports both lxml and xml.etree) does not disable entity resolution, and could lead to arbitrary file reads from an attacker-controlled XML payload. This affects all XML parsing in the codebase. This issue has been addressed in version 0.28.1. All users are advised to upgrade. The only known workaround is to patch the library manually. See GHSA-8h9c-r582-mggc for details.

Vulnerability from github

Published

2023-03-07 20:41

Modified

2024-10-07 21:17

Severity ?

8.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L
8.8 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N

Summary

OWSLib vulnerable to XML External Entity (XXE) Injection

Details

Impact

OWSLib's XML parser (which supports both lxml and xml.etree) does not disable entity resolution for lxml, and could lead to arbitrary file reads from an attacker-controlled XML payload. This affects all XML parsing in the codebase.

Patches

Use only lxml for XML handling, adding resolve_entities=False to lxml's parser: https://github.com/geopython/OWSLib/pull/863

Workarounds

python patch_well_known_namespaces(etree) etree.set_default_parser( parser=etree.XMLParser(resolve_entities=False) )
