Misconfigured Gradle
Don't Return to Misconfigured Package Management (Misconfigured Maven, Misconfigured NPM)
TLDR: Misconfigured Gradle builds occur when dependency management, build scripts, or plugin configurations in Java or Kotlin projects are improperly implemented, leading to vulnerabilities, inefficiencies, or unstable builds. Common issues include dependency conflicts, unoptimized build processes, and insecure plugin usage. Proper configuration ensures secure, efficient, and reliable builds using Gradle.
https://en.wikipedia.org/wiki/Gradle
A misconfigured Gradle setup might involve unresolved or conflicting dependencies due to missing version constraints in the `build.gradle` file. Using outdated or insecure plugins can introduce vulnerabilities or cause compatibility issues. Additionally, failing to leverage Gradle’s caching or parallel execution features can significantly increase build times, impacting development efficiency. Tools like `gradle dependencies` and Dependency Check help analyze and resolve these issues in Gradle builds.
https://docs.gradle.org/current/userguide/dependency_management.html
To optimize and secure Gradle builds, developers should use dependency locking to maintain consistent versions, remove unused libraries, and audit dependencies for known vulnerabilities using tools like Snyk or `gradle audit`. Proper configuration of plugins, such as SpotBugs for static analysis, ensures that security and performance issues are addressed early in the development cycle. Regular updates to Gradle itself and adherence to secure build practices ensure efficient and secure project management.
In Depth
TLDR: Misconfigured Gradle, introduced in 2010, can expose applications to vulnerabilities such as supply chain attacks, data leakage, and remote code execution (RCE). These risks arise from improper dependency resolution, insecure repository configurations, and lack of validation mechanisms, violating several OWASP Top Ten principles, including Input Validation, Access Controls, and secure Policy Enforcement.
Improper input validation in `build.gradle` or `settings.gradle` files allows attackers to inject malicious dependencies into projects. For instance, unverified entries in dependency blocks or repositories can introduce compromised libraries. Enforcing strict validation aligns with OWASP Top Ten guidelines on Input Validation.

Neglecting to secure private repositories in Gradle configurations can result in unauthorized access or manipulation of dependencies. Implementing strong Access Controls and authentication mechanisms ensures only authorized users can modify repositories, meeting OWASP Top Ten’s Access Management standards.

Failing to update outdated dependencies in Gradle projects leaves applications vulnerable to exploits in unpatched libraries. Utilizing tools like Gradle’s dependency report and enabling alerts for vulnerable components ensures compliance with OWASP Top Ten's proactive security practices.

Relying on public repositories like Maven Central or JCenter without validation exposes projects to supply chain attacks. Configuring allowlists to accept only trusted sources ensures compliance with OWASP Top Ten's Policy Enforcement principles.

Logging sensitive details, such as repository URLs or access credentials during Gradle build processes, increases the risk of data leakage. Adopting secure Logging practices, including encrypting sensitive fields, aligns with OWASP Top Ten’s monitoring and auditing standards.

Over-reliance on Gradle's Framework Defaults can result in permissive dependency resolution, such as allowing transitive dependencies without validation. Customizing configurations to enforce strict dependency management complies with OWASP Top Ten's secure Framework Defaults principles.

Failing to enforce signature verification for dependencies in Gradle repositories increases the risk of downloading tampered packages. Ensuring all dependencies are verified using cryptographic signatures complies with OWASP Top Ten's Data Encryption and integrity protection standards.
https://owasp.org/www-community/Data_Encryption
Excessive use of Gradle dependencies without imposing limits on dependency tree size or complexity can lead to denial of service attacks. Implementing resource constraints during dependency resolution mitigates this risk, adhering to OWASP Top Ten’s resource management recommendations.
https://owasp.org/www-community/Denial_of_Service
Neglecting to sandbox build scripts in Gradle configurations can result in RCE if a malicious dependency executes during the build process. Ensuring secure execution of scripts in isolated environments adheres to OWASP Top Ten's guidelines for secure resource management.

Lastly, failing to segregate Gradle configurations between development and production environments can lead to unverified dependencies being deployed in production. Adopting environment-specific configurations ensures alignment with OWASP Top Ten operational best practices.
