The spring-security.xsd file inside the spring-security-config jar is world writable which means that if it were extracted it could be written by anyone with access to the file system.

While there are no known exploits, this is an example of “CWE-732: Incorrect Permission Assignment for Critical Resource” and could result in an exploit. Users should update to the latest version of Spring Security to mitigate any future exploits found around this issue.

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
Spring_security Vmware 5.8.4 (including) 5.8.7 (excluding)
Spring_security Vmware 6.0.4 (including) 6.0.7 (excluding)
Spring_security Vmware 6.1.1 (including) 6.1.4 (excluding)
Spring_security Vmware 5.7.9 (including) 5.7.9 (including)
Spring_security Vmware 5.7.10 (including) 5.7.10 (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.
