CVE-2020-7659 (GCVE-0-2020-7659)

Vulnerability from cvelistv5 – Published: 2020-06-01 12:50 – Updated: 2024-08-04 09:33

Summary

reel through 0.6.1 allows Request Smuggling attacks due to incorrect Content-Length and Transfer encoding header parsing. 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. Note: This project is deprecated, and is not maintained any more.

Severity

No CVSS data available.
