RHSA-2013:0644 - Important: apache-cxf security update

Synopsis

Important: apache-cxf security update

Type/Severity

Security Advisory Important

Topic

An updated apache-cxf package for JBoss Enterprise Application Platform 6.0.1 which fixes two security issues is now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

Apache CXF is an open source services framework.

It was found that the Apache CXF UsernameTokenPolicyValidator and UsernameTokenInterceptor allowed a UsernameToken element with no password child element to bypass authentication. A remote attacker could use this flaw to circumvent access controls applied to web services by omitting the password in a UsernameToken. This flaw was exploitable on web services that rely on WS-SecurityPolicy plain text UsernameTokens to authenticate users. It was not exploitable when using hashed passwords or WS-Security without WS-SecurityPolicy. (CVE-2013-0239)

If web services were deployed using Apache CXF with the WSS4JInInterceptor enabled to apply WS-Security processing, HTTP GET requests to these services were always granted access, without applying authentication checks. The URIMappingInterceptor is a legacy mechanism for allowing REST-like access (via GET requests) to simple SOAP services. A remote attacker could use this flaw to access the REST-like interface of a simple SOAP service using GET requests that bypass the security constraints applied by WSS4JInInterceptor. This flaw was only exploitable if WSS4JInInterceptor was used to apply WS-Security processing. Services that use WS-SecurityPolicy to apply security were not affected. (CVE-2012-5633)

All users of JBoss Enterprise Application Platform 6.0.1 on Red Hat Enterprise Linux 5 and 6 are advised to upgrade to this updated package. The JBoss server process must be restarted for the update to take effect.
