It is a critical remote code execution vulnerability in the Node.js-based server for the development of software. It affects all the versions of the server from v0.12.11 up to the latest v10.14.2.

The vulnerability was discovered by Alibaba, the Chinese e-commerce giant. The company is responsible for developing the software to power the online shopping sites like Taobao, Tmall and Alibaba Cloud.

The remote code execution vulnerability can be exploited by an attacker by sending a specially crafted HTTP request. It can be done by injecting a malicious script into the context of a target application.

In order to exploit this vulnerability, the attacker needs to send a specially crafted HTTP request to the targeted server. The request should include one or more HTML tags that are used to control the flow of execution.

By injecting this sort of request into the server’s response, the attacker can control the flow of execution and can do anything he wants.

Vulnerability Details

The vulnerability is located in the Node.js-based server, which powers software development for Taobao, Tmall and Alibaba Cloud. The remote code execution vulnerability can be exploited by sending a specially crafted HTTP request to the targeted server. It can be done by injecting a malicious script into the context of a target application. In order to exploit this vulnerability, the attacker needs to send a specially crafted HTTP request to the targeted server. The request should include one or more HTML tags that are used to control the flow of execution. By injecting this sort of request into the server’s response, he can control the flow of execution and can do anything he wants.

The Node.js-based Server for the Development of Software

The Node.js-based server for the development of software is susceptible to a critical remote code execution vulnerability. This vulnerability can be exploited by sending a specially crafted HTTP request. The attacker would have to send an HTTP request with one or more HTML tags that are used to control the flow of execution. By injecting this sort of request into the server’s response, the attacker can control the flow of execution and could do anything he wanted.

Attack chain

The attack chain begins with the attacker sending a specially crafted HTTP request to the targeted server. The request should include one or more HTML tags that are used to control the flow of execution. When this happens, the server will respond and execute any script in the response.

Next, the attacker has a chance to take advantage of his remote code execution vulnerability by injecting a malicious script into the context of a target application. An attacker can do this by sending a specially crafted HTTP request to the targeted server again. This time, however, he’ll use two tags:

Vulnerability Details: How to Hack Node.js Server?

To exploit this vulnerability, an attacker needs to send a specially crafted HTTP request to the targeted server. The request should include one or more HTML tags that are used to control the flow of execution.
By injecting this sort of request into the server’s response, the attacker can control the flow of execution and can do anything he wants.

Below are some examples of exploitation:

1) DoS attack: By injecting a large number of requests into the server's response, it will cause a denial-of-service attack on the target system.
2) Information leak: By sending one or more HTML tags in a request, an attacker can control what information is returned in response. This allows him to retrieve sensitive data from vulnerable systems.
