Comma Separated Value(CSV) Injection

Comma Separated Value(CSV) Injection | Report Data

Analysis:

During the analysis, it was observed that there was functionality to export the data in a CSV file and this functionality was affected by the CSV injection vulnerability, also known as Formulae Injection. We could execute a malicious command.

Impact:

Successful exploitation will allow an attacker to execute arbitrary code with the privilege of a currently logged-in user of the system, causing serious damage to the victim’s system like an entire partition can be wiped out or create backdoors as well for later access. Also, an attacker can steal sensitive information from CSV files.

Recommendation:

We recommend that it is always a good practice not to trust user inputs. Also, for the successful execution of the formula, the attacker will have to use the ‘-‘ , ‘=’ , '@', and the pipe (|) is used to execute the binary in the excel software. Hence, it is strongly recommended to whitelist the input and not allow ‘- ‘, ‘|’ , ‘+’, '@', and ‘=’ to mitigate this vulnerability.

Is your webcam exposed on the internet and everyone enjoying your personal moments? | How to check webcam or security camera is exposed on the internet or not?

Nowadays we start using many technology devices in our homes. Many people are installing CCTV or security cameras in their houses, private rooms, offices, private places, etc for security purposes and monitoring, but many of them don't know how to configure that device securely. So let's talk about CCTV and security cameras only. What do most CCTV/Security camera users believe? Most users believe that using a strong username and password on a camera administrative page protects them. (Partially true in the case of online cameras) Example: Why it is partially true? It's partially true because you are protecting only the camera administrative page which is also an important part. Still, you are not protecting the protocol used to control streaming media servers (Real-Time Streaming Protocol ( RTSP )). I have seen many online webcams whose administrative page is secured by strong credentials, but they forget to secure the RTSP protocol which gives me access to the streaming

Web Application Security Testing (WAPT) Interview Questions

Let's Contribute All Together For Creating a Questions Dump What are the vulnerabilities you have to test in the Login form, Payment gateway? What is clickjacking? What is the mitigation of clickjacking? What is CSRF? How to mitigate CSRF? Let's take an example, If a developer implements a CSRF token in a cookie, will it mitigate the CSRF issue? Is it possible to mitigate the CSRF by header? If yes why, if No why? If the data is in JSON format, how you will check the CSRF issue and what are the ways of exploitation? Where to implement the CSRF token and why? If the client doesn't want to change the UI or doesn't want to implement the CSRF tokens, and headers then what mitigation you recommended to the client for CSRF? What is the problem with the per-request token? Is login CSRF possible? Explain login CSRF? Have you ever exploited it? What is the mitigation for login CSRF? Suppose, in an application csrf token is implemented in each request and every request, except th
