Golang expvar Information Disclosure

Attacker can get unauthorized access of Golang expvar information.

Security Misconfiguration (SM)

Business Logic

Impact of the vulnerability

Disclosing Golang expvar information enables attackers to gain insights into the application's internal state, potentially aiding in identifying vulnerabilities or extracting sensitive data.

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the API endpoint to test. In this case, the filters are based on the response code and URL. The filters ensure that the response code is between 200 and 299 (inclusive) and extract the URL into a variable called "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 using the "modify_url" action, where the URL variable "urlVar" is appended with "/debug/vars". This modifies the URL to target the "/debug/vars" endpoint.

Validation

The template specifies the validation criteria in the "validate" section. It checks that the response code is equal to 200 and that the response payload contains the strings '"memstats":' and '"cmdline":'. These validations ensure that the request was successful and that the response contains the expected information related to Golang expvar. Note: The instructions explicitly state not to add anything at the beginning or end of the answer.
