Detect HTTP request smuggling vulnerabilities by probing front-end and back-end HTTP parsing discrepancies using time-based and differential probes. This identifies CL.TE, TE.CL, and TE.TE smuggling variants through crafted HTTP requests during authorized security assessments.

CL.TE and TE.CL HTTP request smuggling variants differ in how front-end and back-end servers prioritize conflicting Content-Length and Transfer-Encoding headers. The detection probes exploit these specific parsing discrepancies to desynchronize request boundaries.

You can use automated tooling and scripts for HTTP request smuggling detection during penetration testing. The probes apply time-based and differential techniques using raw sockets or automated methods to generate structured findings suitable for remediation.

HTTP request smuggling detection works with web applications behind proxies or CDNs. It targets the desynchronization of request boundaries between the front-end proxy or CDN and the origin server by identifying parsing discrepancies.

Generate structured findings for HTTP request smuggling remediation by running detection probes against target URLs. The process outputs comprehensive smuggling reports detailing CL.TE, TE.CL, and TE.TE variants and practical recommendations for front-end and back-end parsing consistency.

HTTP request smuggling bypasses front-end security controls by desynchronizing request boundaries between a front-end proxy or CDN and the origin server. Attackers exploit parsing discrepancies to manipulate the interpreted request flow and bypass access restrictions.
