CVE-2022-36084 : Exploit Details and Defense Strategies

This article provides details about CVE-2022-36084, a vulnerability affecting cruddl software versions prior to 2.7.0 and 3.0.2. The vulnerability allows attackers to inject arbitrary AQL queries when using

@flexSearchFulltext

in schemas.

Understanding CVE-2022-36084

This section covers what CVE-2022-36084 entails, its impact, technical details, and mitigation strategies.

What is CVE-2022-36084?

cruddl, a software for building a GraphQL API for databases, is vulnerable to AQL injection through the use of

@flexSearchFulltext

in schemas. This allows attackers with

READ

permissions to execute arbitrary AQL queries on ArangoDB.

The Impact of CVE-2022-36084

cruddl versions prior to 2.7.0 and 3.0.2 are susceptible to this critical vulnerability. Attackers exploiting this issue can compromise confidentiality, integrity, and availability of affected systems.

Technical Details of CVE-2022-36084

This section delves into the specifics of the vulnerability including its description, affected systems, and exploitation mechanism.

Vulnerability Description

cruddl versions between 1.1.0 and 2.7.0 / 3.0.2 are vulnerable to AQL injection. If

@flexSearchFulltext

is used in schemas, attackers can inject and execute AQL queries via ArangoDB.

Affected Systems and Versions

cruddl versions >= 1.1.0 and < 2.7.0 / < 3.0.2 are impacted. Schemas utilizing

@flexSearchFulltext

are at risk, while those without this feature are not affected.

Exploitation Mechanism

Attackers need

READ

permissions to a root entity type with

@flexSearchFulltext

to exploit the vulnerability. By injecting AQL queries, they can manipulate the database.

Mitigation and Prevention

This section outlines immediate steps to remediate the vulnerability and long-term security practices.

Immediate Steps to Take

Users should update cruddl to versions 2.7.0 or 3.0.2 to patch the vulnerability. As a temporary workaround, removing

@flexSearchFulltext

from schemas can mitigate the risk.

Long-Term Security Practices

Implement secure coding practices, regularly update software, and conduct security audits to prevent future vulnerabilities.

Patching and Updates

Stay informed about security advisories and promptly apply patches. Regularly monitor for updates and security recommendations.
