CrackQL - GraphQL Password Brute-Force And Fuzzing Utility

https://blogger.googleusercontent.com/img/a/AVvXsEgFVmUBDDQP3wgV0lUmJmRUSok2fYnB37fNyhLnV3C8p8Czy16AMK-Hkmphu1P4SeiCvxovoJkYHGGBn1ar-62RvfG9RC0LUMrffJsBuWxpTFlglUB_2bqsKXqfD-sB6gsNxDv-jw2Lnf5uRs2QwXGjuym4wzkglfmxQqfvW5HBlnyYrfBokSwfmsFr=w640-h284 CrackQL is a GraphQL password brute-force and fuzzing utility.

CrackQL is a versatile GraphQL penetration testing tool that exploits poor rate-limit and cost analysis controls to brute-force credentials and fuzz operations. How it works?CrackQL works by automatically batching a single GraphQL query or mutation into several alias operations. It determines the number of aliases to use based on the CSV input variables. After programmatically generating the batched GraphQL document, CrackQL then batches and sends the payload(s) to the target GraphQL API and parses the results and errors. Attack Use CasesCrackQL can be used for a wide range of GraphQL attacks since it programmatically generates payloads based on a list of dynamic inputs. Defense EvasionUnlike Burp Intruder which sends a request for each unique payload, CrackQL evades traditional API HTTP rate-limit monitoring defenses by using multiple alias queries to stuff large sets of credentials into single HTTP requests. To bypass query cost analysis defenses, CrackQL can be optimized into using a series of smaller batched operations (-b) as well as a time delay (-D). Password Spraying Brute-forcingCrackQL is perfect against GraphQL deployments that leverage in-band GraphQL authentication operations (such as the GraphQL Authentication Module). The below password spraying example works against DVGA with the sample-inputs/users-and-passwords.csvdictionary.

sample-queries/login.graphql mutation {
login(username: {{username|str}}, password: {{password|str}}) {
accessToken
}
}
Two-factor Authentication OTP BypassIt is possible to use CrackQL to bypass two-factor authentication by sending all OTP (One Time Password) tokens

sample-queries/otp-bypass.graphql mutation {
twoFactor(otp: {{otp|int}}) {
accessToken
}
}
User Account EnumerationCrackQL can also be used for enumeration attacks to discover valid user ids, usernames and email addresses

sample-queries/enumeration.graphql query {
signup(email: {{email|str}}, password: {{password|str}}) {
user {
email
}
}
}
Insecure Direct Object ReferenceCrackQL could be used to iterate over a large number of potential unique identifiers in order to leak object information

sample-queries/idor.graphql query {
profile(uuid: {{uuid|int}}) {
name
email
picture
}
}
General FuzzingCrackQL can be used for general input fuzzing operations, such as sending potential SQLi and XSS payloads. InputsCrackQL will generate payloads based on input variables defined by a CSV file. CrackQL requires the CSV header to match the input name.

sample-inputs/usernames_and_passwords.csv username, password
admin, admin
admin, password
admin, pass
admin, pass123
