Rules
What the policy asks of you, and the bug types it won't reward, quoted from Office for National Statistics (ONS)'s policy. "We" in these lines means the program, not this site.
While testing
-
access unnecessary amounts of data; two or three records are enough to demonstrate most vulnerabilities, such as an enumeration or direct object reference vulnerability
-
use high-intensity invasive or destructive technical security scanning tools to find vulnerabilities
-
violate the privacy of ONS users, staff, contractors, services or systems, for example, by sharing, redistributing and/or not properly securing data retrieved from our systems or services
-
communicate any vulnerabilities or associated details using methods not described in this policy
-
modify data in any ONS systems or services
-
disrupt any ONS services or systems
-
socially engineer, “phish”, or physically attack ONS staff or infrastructure
-
You must also not disclose any vulnerabilities in ONS systems or services to third parties or the public before the ONS has confirmed that they have been mitigated or rectified.
Not accepted
-
volumetric vulnerabilities, for example, simply overwhelming a service with a high volume of requests
-
reports of non-exploitable vulnerabilities or indicating that our services do not fully align with “best practice”, for example, missing security headers
-
TLS configuration weaknesses, for example, “weak” cipher suite support or the presence of TLS 1.0 support
