Apache Tomcat contains an unspecified vulnerability that allows for remote code execution if JmxRemoteLifecycleListener is used and an attacker can reach Java Management Extension (JMX) ports. This CVE exists because this listener wasn't updated for consistency with the Oracle patched issues for CVE-2016-3427 which affected credential types.

A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. An attacker can exploit the flaw if all of the following are true: An attacker is able to control the contents and name of a file on the server. The server is configured to use the PersistenceManager with a FileStore. The PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker-provided object to be deserialized. The attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over. If all these conditions are true, the attacker can use a specifically crafted request to trigger Remote Code Execution through deserialization of the file under their control.

This flaw affects the following Tomcat versions: 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, and 7.0.0 to 7.0.103.

Pivotal Spring Framework is vulnerable to cross-site tracing, caused by a flaw in the HiddenHttpMethodFilter in Spring MVC. By persuading a victim to visit a specially-crafted Web site, an attacker could exploit this vulnerability to cause the victim's browser to invoke a TRACE request to return sensitive header information including cookies or authentication data from third-party domains.

Apache Tomcat could allow a remote attacker to execute arbitrary code on the system, caused by a file read/inclusion vulnerability in the AJP connector. By sending a specially-crafted request, an attacker could exploit this vulnerability to read web application files from a vulnerable server and upload malicious JavaServer Pages (JSP) code within a variety of file types and execute arbitrary code on the system.

Note: This vulnerability is known as Ghostcat.

A flaw was found in Spring Security in combination with Spring Framework versions prior to 5.0.6 contains an authorization bypass when using method security. An unauthorized malicious user can gain unauthorized access to methods that should be restricted.

Apache Tomcat is vulnerable to HTTP request smuggling, caused by a flaw when handling unusual Transfer-Encoding HTTP header. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.

A flaw was found in Spring Framework, versions 5.0.x prior to 5.0.6, versions 4.3.x prior to 4.3.17, and older unsupported versions allows applications to expose STOMP over WebSocket endpoints with a simple, in-memory STOMP broker through the spring-messaging module. A malicious user (or attacker) can craft a message to the broker that can lead to a regular expression, denial of service attack.

A flaw was found in Apache tomcat. When the default servlet returned a redirect to a directory (e.g. redirecting to /foo/ when the user requested /foo) a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

In Eclipse Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older, the server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches the requested path. The default server behavior on jetty-distribution and jetty-home will include at the end of the Handler tree a DefaultHandler, which is responsible for reporting this 404 error, it presents the various configured contexts as HTML for users to click through to. This produced HTML includes output that contains the configured fully qualified directory base resource location for each context.

Jetty through 9.4.x contains a timing channel attack in util/security/Password.java, which allows attackers to obtain access by observing elapsed times before rejection of incorrect passwords.

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.

Apache Tomcat versions 7.0.0 to 7.0.84, 8.0.0.RC1 to 8.0.49 and 8.5.0 to 8.5.27 does not properly handle the URL empty string ("") when used as part of a security constraint definition. This can lead to the security constraint being ignored, leading to unitended exposure of resources.

A flaw was found in HTTP/2 (modhttp2) connections in Apache HTTP Server httpd 2.4.17 to 2.4.37. A DoS can be triggered by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data.

A Prototype Pollution vulnerability was found in jquery. Untrusted JSON passed to the extend function could lead to modifying objects up the prototype chain, including the global Object. A crafted JSON object passed to a vulnerable method could lead to denial of service or data injection, with various consequences.

In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.

Affected versions of jquery interpret text/javascript responses from cross-origin ajax requests, and automatically execute the contents in jQuery.globalEval, even when the ajax request doesn't contain the dataType option.

Recommendation

Update to version 3.0.0 or later.

The ASN.1 parser in Bouncy Castle Crypto (aka BC Java) 1.63 can trigger a large attempted memory allocation, and resultant OutOfMemoryError error, via crafted ASN.1 data. This is fixed in 1.64.

Apache Axis 1.x up to and including 1.4 is vulnerable to a cross-site scripting (XSS) attack in the default servlet/services.

A Server Side Request Forgery (SSRF) vulnerability affected the Apache Axis 1.4 distribution that was last released in 2006. Security and bug commits commits continue in the projects Axis 1.x Subversion repository, legacy users are encouraged to build from source. The successor to Axis 1.x is Axis2, the latest version is 1.7.9 and is not vulnerable to this issue.
