GHSA-F5GC-P5M3-V347

Vulnerability from github – Published: 2020-12-02 18:28 – Updated: 2024-10-09 20:55

Summary

XXE in petl

Details

Impact

Information Disclosure

Summary

petl is a Python library that provides functions for extraction, transformation, and loading (ETL) of data.

petl before 1.68, in some configurations, allows resolution of entities in XML input.

An attacker who is able to submit XML input to an application using petl can disclose arbitrary files on the file system in the context of the user under which the application is running.

Affected Applications

Applications that:

accept attacker-supplied XML input that is processed using petl < 1.68
return the response generated by petl back to the attacker
configure lxml as the underlying XML processing library used by petl
have read privileges in filesystem files with sensitive information

Mitigation

Update to petl >= 1.68

Workarounds

Assure there is no user/external access to the application using petl
Assure your application is not using the function fromxml()
