Server Version Exposed Via Response Header

Server Version Exposed Via Response Header

Attacker can obtain information about the software version and other identifying details of the server software running on a remote system.

Server Version Disclosure (SVD)

"The endpoint appears to be vulnerable to server version disclosure attack. The original request was replayed by modifying it with an invalid url. The server response contained a header named Server which contained information about the server software and its version number. "<b>Background:</b> Server version disclosure vulnerabilities are often considered low-risk compared to other types of security flaws. However, they can still provide attackers with valuable information that aids in the planning and execution of subsequent attacks. For example, knowing the specific version of a web server software can help an attacker identify publicly known vulnerabilities associated with that version and exploit them to gain unauthorized access to the server or compromise its integrity.

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the APIs to be tested. In this case, it filters the APIs based on the response code, ensuring that it falls within the range of 200 to 299. It also extracts the URL from the response and assigns it to the variable "urlVar".

Execute request

The template uses the "execute" section to define the type of request to be executed. In this case, it is a single request. The request is modified by replacing the URL with the value of the "urlVar" variable.

Validation

The template uses the "validate" section to define the validation criteria for the response. It checks that the response code falls within the range of 200 to 299 and also validates the response headers. Specifically, it checks if the "Server" header exists and its value matches the specified regex pattern, which captures the server software version number.
