An issue was discovered in Gradle Enterprise 2018.2 - 2020.2.4. The CSRF prevention token is stored in a request cookie that is not annotated as HttpOnly. An attacker with the ability to execute arbitrary code in a users browser could impose an arbitrary value for this token, allowing them to perform cross-site request forgery.

Weakness

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

Affected Software

Name Vendor Start Version End Version
Enterprise Gradle 2018.2 (including) 2020.2.4 (including)

Potential Mitigations

  • Run the code in a “jail” or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
  • OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
