CVE-2020-1935 - Medium Severity Vulnerability

Vulnerable Library - tomcat-embed-core-9.0.14.jar

Core Tomcat implementation

Path to dependency file: /pom.xml

Path to vulnerable library: /home/wss-scanner/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.14/tomcat-embed-core-9.0.14.jar

Dependency Hierarchy: - spring-boot-starter-web-2.1.2.RELEASE.jar (Root Library) - spring-boot-starter-tomcat-2.1.2.RELEASE.jar - :x: **tomcat-embed-core-9.0.14.jar** (Vulnerable Library)

Found in HEAD commit: cd0f4c8458f405daaa5f18e4342d4e8479749d18

Vulnerability Details

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.
