Vulnerability make it easier to hack Apache bRPC environments


Apache bRPC is a C++-based industrial-grade RPC framework, and it has lately come under criticism as a result of a significant security flaw. bRPC is an Apache Top-Level Project that is used extensively in high-performance systems such as search, storage, machine learning, advertising, and recommendation. This vulnerability, identified as CVE-2023-31039, has a severity rating of “important” and affects all versions of Apache bRPC from 0.9.0 to 1.4.9 on all supported systems.

An attacker may execute arbitrary code if they successfully exploit the vulnerability that exists in the ServerOptions::pid_file argument of the Apache bRPC server. If the vulnerability is exploited. An adversary may run arbitrary code with the same permissions as the bRPC process by manipulating the ServerOptions pid_file option at the beginning of the bRPC server. This has the potential to compromise the system’s integrity.

Users of Apache bRPC are strongly encouraged to take the following actions in order to reduce the potential harm caused by the vulnerability known as CVE-2023-31039:

  1. Ensure that you are using Apache bRPC version 1.5.0 or a later version. The most recent version may be obtained from this location.
  2. Users have the option of applying a patch to their current installation of bRPC if it is not possible for them to upgrade to a more recent version of the software. You may get this update by following this link.

In addition to putting into action the solutions described above, it is essential to make certain that the brpc::ServerOptions::pid_file is set based on input from the user. The Apache bRPC framework’s overall security is maintained and improved thanks in part by this step, which helps prevent unwanted access.
