Testing for remote code injection vulnerability

Details of BNVL-2018-0041

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 analysis by the AI-powered Attack Vector Miner. More than 100 vulnerability types have been discovered with this project so far, so we decided to publish this platform to help to keep 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

CVE ID: Na

Description: 

Code Injection is the general term for attack types which consist of injecting code that is then interpreted/executed by the application. This type of attack exploits poor handling of untrusted data. These types of attacks are usually made possible due to a lack of proper input/output data validation, for example:

allowed characters (standard regular expressions classes or custom)
data format
amount of expected data
Code Injection differs from Command Injection in that an attacker is only limited by the functionality of the injected language itself. If an attacker is able to inject PHP code into an application and have it executed, he is only limited by what PHP is capable of. Command injection consists of leveraging existing code to execute commands, usually within the context of a shell.
