Advisory Release Date: 2023-08-17 11:58 Pacific
Advisory Updated Date: 2023-08-23 00:18 Pacific
Severity:
Medium
Issue Overview:
A flaw was found in Apache Tomcat. The HTTP header parsing code used an approach to end-of-line (EOL) parsing that allowed some invalid HTTP headers to be parsed as valid. This led to the possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. The highest threat with this vulnerability is system availability. (CVE-2020-1935)
