CVE-2021-3923

Read Time:17 Second

A flaw was found in the Linux kernel’s implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.

For example in the file plugin.php, the function iv_directories_update_profile_setting() uses update_user_meta with any data provided by the ajax call, which can be used to give the logged in user admin capabilities. Since the plugins allow user registration via a custom form (even if the blog does not allow users to register) it makes any site using it vulnerable.
