What does the BNVL label mean?

BitNinja Server Security's BNVL identifiers are intended for use to identify publicly known information security vulnerabilities in publicly released software packages. This project was designed to collect and analyze attack information from the BitNinja network after cluster analyzis by the AI-powered Attack Vector Miner. More than 100 vulnerabilty types have been discovered with this project so far, so we decided to publish this platform to help keeping Linux server owners up-to-date.

Important! All listed BNVL vulnerabilities are protected by BitNinja PRO, so please check your configurations if your infrastructure is affected by any of them.

Syntax for BNVL labels:

BNVL prefix + Year + Arbitrary Digits

Unfortunately, out of the box WordPress has one component which can be exploited for malicious use. By default, the pingback (which allows you to record who linked to your blog) doesn’t have any form of validation to ensure the “pingback” was from the requesting server. This means that a request can be made against a fully patched, clean server and the return request will go to your intended target.
