No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Security vulnerability in Apache bRPC <=1.6.0 on all platforms allows attackers to inject XSS code to the builtin rpcz page. An attacker that can send http request to bRPC server with rpcz enabled can inject arbitrary XSS code to the builtin rpcz page.

Solution (choose one of three):

  • upgrade to bRPC > 1.6.0, download link: https://dist.apache.org/repos/dist/release/brpc/1.6.1/
  • If you are using an old version of bRPC and hard to upgrade, you can apply this patch:  https://github.com/apache/brpc/pull/2411
  • disable rpcz feature
