View Source>_Auth Bypass Kit
Collection of authentication bypass techniques packaged as a CLI — JWT attacks, OAuth flaws, SAML misconfigurations, and session fixation .
Key Features
- 'JWT Attack Suite: alg:none, algorithm confusion, weak secret wordlist',
- 'OAuth Bypass: implicit flow downgrade, PKCE bypass, redirect_uri manipulation',
- 'SAML Attacks: XML Signature Wrapping, comment injection, XSW variants',
- 'Session Attacks: session fixation, CSRF token prediction, cookie scope manipulation'
Example Usage
$
'odivex-tools auth --target https://app.com/login --technique jwt-none',$
'odivex-tools auth --target https://app.com --technique oauth-implicit',$
'odivex-tools auth --target https://app.com/saml/acs --technique xml-signature-wrapping'Setup
Install via the OdiVex CLI framework:
npm install -g odivex-tools## The Authentication Attack Surface
Modern web applications use layered authentication systems — JWT-based APIs, OAuth/OIDC federation, SAML SSO for enterprise. Each layer has its own attack surface, and Auth Bypass Kit covers all of them.
## Technique Reference
### XML Signature Wrapping (XSW)
XSW attacks target SAML implementations that verify the signature before parsing the full document. By duplicating the signed element and injecting a malicious sibling, attackers can forge assertions:
```bash
odivex-tools auth --target https://app.com/saml/acs \
--technique xml-signature-wrapping \
--role admin \
--saml-response original_response.xml
OAuth State Parameter Bypass
When OAuth implementations don''t validate the state parameter, CSRF attacks against the OAuth flow become trivial:
odivex-tools auth --target https://app.com \
--technique oauth-csrf \
--callback https://app.com/oauth/callback
```'
