A vulnerability related to weak permissions was detected in Avaya Aura Application Enablement Services web application, allowing an administrative user to modify accounts leading to execution of arbitrary code as the root user. This issue affects Application Enablement Services versions 8.0.0.0 through 8.1.3.4 and 10.1.0.0 through 10.1.0.1. Versions prior to 8.0.0.0 are end of manufacturing support and were not evaluated.
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.

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.
