Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Proxy Basic Auth unconditionally overwrote the Authorization header, allowing a malicious proxy to inject credentials and bypass the caller's intended authentication.
Auth Bypass: STS SecurityToken was placed in query parameters instead of the x-acs-security-token header, potentially allowing signature validation to be bypassed or tokens to be stripped.
Predictable Nonce: UUID-based SignatureNonce was predictable, enabling request replay or forgery that could lead to authentication bypass.
