propel/propel1 SQL injection possible with limit() on MySQL

Critical severity GitHub Reviewed Published May 20, 2024 to the GitHub Advisory Database • Updated May 20, 2024

Package

composer propel/propel1 (Composer)

Affected versions

>= 1, <= 1.7.1

Patched versions

1.7.2

Description

The limit() query method is susceptible to catastrophic SQL injection with MySQL.

For example, given a model User for a table users:

UserQuery::create()->limit('1;DROP TABLE users')->find();

This will drop the users table!

The cause appears to be a lack of integer casting of the limit input in either Criteria::setLimit() or in DBMySQL::applyLimit(). The code comments there seem to imply that casting was avoided due to overflow issues with 32-bit integers.

This is surprising behavior since one of the primary purposes of an ORM is to prevent basic SQL injection.

This affects all versions of Propel: 1.x, 2.x, and 3.

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.
