Server Security Misconfiguration

Server Security Misconfiguration

Overview of the Vulnerability

Server security misconfigurations result from errors in the setup and deployment of a web server. These misconfigurations can lead to a broad range of issues which could allow a malicious attacker to manipulate the server and retrieve, change, or delete content.

Business Impact

Depending on the type of misconfiguration found in the server, exposure or manipulation of data from within it could lead to financial loss and reputational damage for the business.

Steps to Reproduce

1. Enable a HTTP intercept proxy, such as Burp Suite or OWASP ZAP, to record and intercept web traffic from your browser

2. Use a browser to navigate to: {{URL}}

3. Using the HTTP intercept proxy, capture the response

4. Observe the server security misconfiguration

Guidance

Provide a step-by-step walkthrough with a screenshot on how you exploited the vulnerability. This will speed triage time and result in faster rewards. Your submission must include evidence of the vulnerability and not be theoretical in nature.

For a server security misconfiguration vulnerability, please include a screenshot or video to easily demonstrate and reproduce the issue. Attempt to escalate the server security misconfiguration to perform additional actions (such as an account takeover or CSRF bypass to perform a sensitive action). If this is possible, provide a full Proof of Concept (PoC).

Recommendation(s)

It is recommended that all servers are managed through a repeatable configuration process which covers server hardening, updates, security headers, and segmentation. There should also be a verification process which tests the effectiveness of the configurations and settings.
