Summary IBM Worklight has addressed the following vulnerability. WAS traditional and liberty vulnerable to CVE-2014-7810 Vulnerability Details CVEID: CVE-2014-7810 DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by the use of expression language. A...

Insecure Defaults

Apache Tomcat is vulnerable to insecure defaults. The CORS filter provided by default is insecure as it enables supportsCredentials for all origins. This can allow a malicious user unauthorized access to sensitive resources...

Cross-site Scripting (XSS) Or Information Disclosure

Apache Tomcat is vulnerable to cross-site scripting XSS attacks and information disclosure. It permits invalid characters when parsing the HTTP request line. Attackers can exploit it, in conjunction with a proxy that also permits the invalid characters but with a different interpretation, to inje...

SecurityManager Bypass

Apache Tomcat Jasper 6.x before 6.0.44, 7.x before 7.0.58, and 8.x before 8.0.16 allows the bypass a SecurityManager protection mechanism by using a web application that uses the incorrect privileges during an EL evaluation. This is caused because it does not take into account the possibility of ...

Authorization Bypass

modjk is vulnerable to authorization bypass attacks. The vulnerability exists as Apache Tomcat Connectors modjk before 1.2.41 ignores JkUnmount rules for subtrees of previous JkMount rules, which allows remote attackers to access otherwise restricted artifacts via unspecified vectors...

Denial Of Service (DoS) In ChunkedInputFilter

java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat 6.x before 6.0.42, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle attempts to continue reading data after an error has occurred, which allows remote attackers to conduct HTTP request smuggling attacks...

Denial Of Service (DoS) Memory Consumption

Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle cases where an HTTP response occurs before finishing the reading of an entire request body, which allows remote attackers to cause a denial of service memory consumption via a series of aborted uploa...

Authentication Bypass In The Replay-countermeasure Functionality

The replay-countermeasure functionality in the HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 tracks cnonce aka client nonce values instead of nonce aka server nonce and nc aka nonce-count values, which makes it easi...

Request-smuggling Attacks

Apache Tomcat Coyote before 6.0.39, 7.x before 7.0.47, and 8.x before 8.0.0-RC3, doesn't handle inconsistent HTTP request headers well when an HTTP or AJP connector is used. This allows remote attackers to incorrectly identify the requests length and conduct request-smuggling attacks through...

XML External Entity (XXE)

Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 allows attackers to obtain Tomcat internals information by leveraging the presence of an untrusted web application with a context.xml, web.xml, .jspx, .tagx, or .tld XML document containing an external entity declaration in...

Denial Of Service (DoS)

MultipartStream.java in Apache Commons FileUpload before 1.3.1, as used in Apache Tomcat, JBoss Web, and other products, allows remote attackers to cause a denial of service infinite loop and CPU consumption via a crafted Content-Type header that bypasses a loop's intended exit conditions...

Arbitrary File Write

jbossweb is vulnerable to arbitrary file write attacks. The vulnerability exists as the readObject method in the DiskFileItem class in Apache Tomcat and JBoss Web, as used in Red Hat JBoss Enterprise Application Platform 6.1.0 and Red Hat JBoss Portal 6.0.0, allows remote attackers to write to...

Cross-site Request Forgery (CSRF)

org/apache/catalina/filters/CsrfPreventionFilter.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.32 allows remote attackers to bypass the cross-site request forgery CSRF protection mechanism via a request that lacks a session identifier...

Denial Of Service (DoS) Memory Consumption

java/org/apache/coyote/http11/InternalNioInputBuffer.java in the HTTP NIO connector in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28 does not properly restrict the request-header size, which allows remote attackers to cause a denial of service memory consumption via a large amount of head...

Denial Of Service (DoS) Resource Consumption

Integer overflow in the parseChunkHeader function in java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service resource consumption via a malformed chunk size in chunke...

Weak Authentication

java/org/apache/catalina/authenticator/FormAuthenticator.java in the form authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before 7.0.33 does not properly handle the relationships between authentication requirements and sessions, which allows remote attackers to inject a...

Authentication Bypass When FORM Authentication Is Used

org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a previous setUserPrincipal call and then placing /jsecuritycheck at the end of a URI. Wh...

Authentication Bypass By Sniffing Valid Network Requests

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the...

The vulnerability of the CORS component of Apache Tomcat servers allows attackers to access protected information.

The vulnerability of the CORS component in Apache Tomcat servers is related to insufficient access control. Exploiting this vulnerability can allow an attacker operating remotely to gain unauthorized access to protected data using the HTTP protocol...
