Greetings, readers! Hi! My Name is Vaibhavi and I’m an experienced cybersecurity practitioner devoted to hardening the digital world from ever-developing dangers. I take on one specific issue that is not commonly apparent on web applications — Information disclosure IDVs. Since my field is on cybersecurity, understanding and eradicating vulnerabilities is very crucial for me.

Information disclosure vulnerabilities – what are they? The details here and some implications. The vulnerabilities occupy an important place in the OWASP’s Top 10 ranking, which demonstrates its importance and occurrence in cyber security.


What is Information Disclosure Vulnerability?

Security weaknesses called as information disclosure vulnerabilities accidentally reveal information that would otherwise be accessed by unauthorised people. Such weaknesses take different shapes—from accidentally disclosed information resulting from error messages to insecure APIs and poorly configured configuration files. It is important to understand the kind of weaknesses that exist and how they can protect their digital properties and ensure security on websites.


Finding Information Disclosure Vulnerabilities: Tools and Techniques

1. Google Dorks

Google Dorks, those specialized search queries designed to unveil vulnerabilities in web applications, are a powerful ally in our quest:

Identifying Open Directories:

Use queries like intitle:index.of to discover open directories containing sensitive information.

Example: intitle:index.of password

Exploring Specific File Types:

Leverage queries such as filetype:xml to unearth XML files that may harbor sensitive data.

Example: filetype:xml confidential

2. OSINT (Open Source Intelligence)

Harnessing the power of Open Source Intelligence allows us to gather information from publicly available sources:

Social Media Analysis:

Scrutinize social media platforms for unintentional data disclosures by organizations or individuals associated with the web application.

Example: Analyzing public posts for mentions of sensitive data like passwords or API keys.

WHOIS Lookups:

Conduct WHOIS lookups to gather information about domain ownership and associated contacts.

Example: whois

3. Shodan

Shodan, the search engine for connected devices, becomes an instrumental tool in identifying potential vulnerabilities:

Device-Specific Searches:

Employ Shodan to search for specific devices or services related to the web application, unveiling potential security gaps.

Example: apache country:US

Banner Grabbing:

Extract banners and information from devices to identify any exposed or misconfigured services.

Example: Searching for HTTP banners that may reveal version information.

4. GitHub Recon

GitHub Recon involves scouring repositories for unintentional data disclosures:

Search for Sensitive Files:

Utilize queries like filename:config to locate configuration files that may contain sensitive information.

Example: filename:database.yml

Review Commit History:

Analyze the commit history to trace any unintentional disclosures or changes containing sensitive data.

Example: Examining commit messages for mentions of confidential information.



The ways of cyber threats are also becoming more advanced as the digital world progresses. One of the most dangerous is information disclosure vulnerabilities included under the OWASP Top 10. Identification and intervention pro-actively should be prioritized. Bringing together techniques such as Google Dorks, OSINT, Shodan, and GitHub Recon, enables security personnel to enhance perimeter and consequently counter future breach instances. Keep yourself updated, be conscious, and use those techniques so as you make your web applications secure even within the changing environment. also visit our previous blogs for more
