DBAL 3 SQL Injection Security Vulnerability

Critical severity GitHub Reviewed Published Nov 15, 2021 in doctrine/dbal • Updated Feb 6, 2024

Package

composer doctrine/dbal (Composer)

Affected versions

>= 3.0.0, < 3.1.4

Patched versions

3.1.4

Description

We have released a new version Doctrine DBAL 3.1.4 that fixes a critical SQL injection vulnerability in the LIMIT clause generation API provided by the Platform abstraction.

We advise everyone using Doctrine DBAL 3.0.0 up to 3.1.3 to upgrade to 3.1.4 immediately.

The vulnerability can happen when unsanitized input is passed to many APIs in Doctrine DBAL and ORM that ultimately end up calling AbstractPlatform::modifyLimitQuery.

As a workaround you can cast all limit and offset parameters to integers before passing them to Doctrine APIs.

This vulnerability has been assigned CVE-2021-43608.

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.
