Description

CKAN has Unauthenticated SQL Injection and Authorization Bypass in datastore_search_sql

Impact

A vulnerability in datastore_search_sql allowed attackers to inject SQL in order to gain access to private resources and PostgreSQL system information.

Patches

The issue has been patched in CKAN 2.10.10 and CKAN 2.11.5

Workarounds

Disable the DataStore SQL search (ckan.datastore.sqlsearch.enabled = false). Note that the SQL search is disabled by default.

More information

As stated in the [documentation](https://docs.ckan.org/en/2.11/maintaining/configuration.html#ckan-datastore-sqlsearch-enabled), this action function has protections that offer some safety but are not designed to prevent all types of abuse. Depending on the sensitivity of private data in a project's DataStore and the likelihood of abuse of a consuming site, a developer may choose to disable this action function or restrict its use with a [IAuthFunctions](https://docs.ckan.org/en/2.11/extensions/plugin-interfaces.html#ckan.plugins.interfaces.IAuthFunctions) plugin.
