Huawei OceanStor 2800 V3, V300R003C00, V300R003C20, OceanStor 5300 V3, V300R003C00, V300R003C10, V300R003C20, OceanStor 5500 V3, V300R003C00, V300R003C10, V300R003C20, OceanStor 5600 V3, V300R003C00, V300R003C10, V300R003C20, OceanStor 5800 V3, V300R003C00, V300R003C10, V300R003C20 have an improper access control vulnerability. Due to incorrectly restrict access to a resource, an attacker with high privilege may exploit the vulnerability to query some information or send specific message to cause some service abnormal.


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, 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.
