Advisory Updated Date: 2020-11-16 20:47 Pacific
Severity: Medium
References: CVE-2020-25613 

Issue Overview:

An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613 )
