CVE-2020-1935 (GCVE-0-2020-1935)
Vulnerability from cvelistv5 – Published: 2020-02-24 21:11 – Updated: 2024-08-04 06:53
VLAI?
Summary
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a 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. Such a reverse proxy is considered unlikely.
Severity ?
No CVSS data available.
