GHSA-H385-52J6-9984

Vulnerability from github – Published: 2020-10-20 19:15 – Updated: 2021-01-13 19:25

Summary

Withdrawn: HTTP Request Smuggling in Agoo

Details

Withdrawn reason

Withdrawn on 1/13/2021 due to this comment from the maintainer. This is no longer considered a vulnerability.

Original description

agoo through 2.12.3 allows request smuggling attacks where agoo is used as a backend and a frontend proxy also being vulnerable. It is possible to conduct HTTP request smuggling attacks by sending the Content-Length header twice. Furthermore, invalid Transfer Encoding headers were found to be parsed as valid which could be leveraged for TE:CL smuggling attacks.

CVE-2020-7670 (GCVE-0-2020-7670)

Vulnerability from cvelistv5 – Published: 2020-06-10 15:36 – Updated: 2024-08-04 09:41

Summary

agoo prior to 2.14.0 allows request smuggling attacks where agoo is used as a backend and a frontend proxy also being vulnerable. HTTP pipelining issues and request smuggling attacks might be possible due to incorrect Content-Length and Transfer encoding header parsing. It is possible to conduct HTTP request smuggling attacks where `agoo` is used as part of a chain of backend servers due to insufficient `Content-Length` and `Transfer Encoding` parsing.

Severity ?
