Critical Vulnerability: Exposure of Sensitive Data in Env.JS
Hello Hackers,
I’m Ashish Rai, a dedicated security researcher and bug hunter, with a track record of securing more than 58 companies by identifying and mitigating vulnerabilities.
How I Found a Critical Vulnerability: Exposure of Sensitive Data
In my journey as a security researcher and ethical hacker, uncovering vulnerabilities that could have severe implications for an organization is both a responsibility and a learning experience. One such discovery involved a critical security vulnerability: the exposure of sensitive data in a publicly accessible file. Here, I will detail how I identified the issue, its potential impact, and the recommendations I provided to mitigate the risk.
The Discovery
Tools I have used to find this vulnerability is Sudomy , katana, httpx , and burpsuite
Sudomy = https://github.com/screetsec/Sudomy
Used this command = ./sudomy -d target.com -dP -eP -rS -cF -pS -tO -gW — httpx — dnsprobe -aI webanalyze -sS
Next, follow the interest path where you’ll find numerous valuable files and URLs. Collect them and save them in a new file called new.txt. Afterward, focus on sorting the JavaScript files, which are a critical part of this process. For example, you can use the following command to sort: cat ./interest/interesturi-js.out | grep "env.js"
If you will get https://target.com/env.js file open it and Boom it will show some juicy data
Impact Analysis
The exposure of sensitive data in the env.js file posed a multitude of risks to the organization, including but not limited to:
- Unauthorized Access: Attackers could exploit the credentials to access internal systems.
- Compromise of Authentication Credentials: Hardcoded keys and passwords could enable unauthorized operations.
- Data Breaches: Sensitive customer or financial data could be exposed, leading to legal and compliance violations.
- Financial and Reputational Damage: The bank’s trustworthiness and financial stability could be impacted due to exploitation by malicious actors.
Conclusion
The exposure of sensitive data in the env.js file was a critical security vulnerability that required immediate attention. Upon identifying and reporting the issue, I collaborated with the concerned parties to ensure swift remediation. By implementing the recommended mitigation strategies, organizations like IndusInd Bank can significantly reduce the risk of unauthorized access, data breaches, and associated financial and reputational damages.
