HackenProof, a Web3 bug bounty platform, recently rewarded a researcher for identifying an Information Disclosure vulnerability classified as Low severity. The journey from Informative → Triaged → Paid highlights the importance of persistence in bug hunting.
You Should Know:
1. What is Information Disclosure?
Information Disclosure occurs when a system unintentionally reveals sensitive data (e.g., internal paths, API keys, user details).
Example:
curl -I https://example.com
Check for server headers exposing software versions.
2. Common Tools to Detect Info Leaks
- Nmap (Network Scanning):
nmap -sV --script=http-enum,http-title <target>
- Dirb/Dirbuster (Directory Bruteforcing):
dirb http://example.com -X .php,.bak
- Burp Suite (Proxy Analysis):
Intercept responses for hidden data in headers/body.
3. Exploiting Misconfigurations
- AWS S3 Buckets:
aws s3 ls s3://bucket-name --no-sign-request
- GitHub Dorks:
site:github.com "api_key"
4. Preventing Info Leaks
- Disable Server Version Headers (Apache):
ServerTokens Prod
- Sanitize Error Messages (PHP):
error_reporting(0);
What Undercode Say
Information disclosure, though often low-risk, can chain into SQLi, XSS, or authentication bypass. Always:
– Fuzz endpoints with ffuf:
ffuf -w wordlist.txt -u https://target/FUZZ
– Monitor GitHub for leaked secrets:
gitleaks --repo-url=https://github.com/user/repo
– Analyze JS files for hardcoded keys:
curl -s https://target/app.js | grep -E "api|key|token"
Expected Output:
A systematic approach transforms “Informative” into “Paid”. Keep hunting!
