Potential log injection in reset user endpoint in CKAN

Moderate severity GitHub Reviewed Published Mar 13, 2024 in ckan/ckan • Updated Mar 13, 2024

Package

pip ckan (pip)

Affected versions

< 2.9.11
>= 2.10.0, < 2.10.4

Patched versions

2.9.11
2.10.4

Description

A user endpoint didn't perform filtering on an incoming parameter, which was added directly to the application log. This could lead to an attacker injecting false log entries or corrupt the log file format.

Patches

This has been fixed in the CKAN 2.9.11 and 2.10.4 versions

Workarounds

Override the /user/reset endpoint to filter the id parameter in order to exclude newlines

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
