TITLE

Apache Commons FileUpload vulnerable to denial-of-service (DoS)

DESCRIPTION

The MultipartStream class in Apache Commons Fileupload before 1.3.2, as used in Apache Tomcat 7.x before 7.0.70, 8.x before 8.0.36, 8.5.x before 8.5.3, and 9.x before 9.0.0.M7 and other products, allows remote attackers to cause a denial of service (CPU consumption) via a long boundary string. Apache Commons FileUpload provided by the Apache Software Foundation contains a flaw when processing multi-part requests, which may lead to a denial-of-service (DoS). TERASOLUNA FW(Struts1) Team of NTT DATA Corporation reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.Processing a specially crafted request may result in the server's CPU resources to be exhausted. Apache Commons FileUpload is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the application to become unresponsive; resulting in a denial-of-service condition. (CVE-2016-3092) 3. The JBoss server process must be restarted for the update to take effect. It is based on JBoss Application Server 7 and incorporates multiple open-source projects to provide a complete Java EE platform solution. Users of EAP 6.4.10 jboss-ec2-eap are advised to upgrade to these updated packages, which add this enhancement. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201705-09 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Apache Tomcat: Multiple vulnerabilities Date: May 18, 2017 Bugs: #575796, #586966, #595978, #615868 ID: 201705-09 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Apache Tomcat, the worst of which could lead to privilege escalation.

Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. The following packages have been upgraded to a newer upstream version: tomcat (7.0.69). (BZ#1287928) Security Fix(es): * A CSRF flaw was found in Tomcat's the index pages for the Manager and Host Manager applications. These applications included a valid CSRF token when issuing a redirect as a result of an unauthenticated request to the root of the web application. This token could then be used by an attacker to perform a CSRF attack. (CVE-2015-5351) * It was found that several Tomcat session persistence mechanisms could allow a remote, authenticated user to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that placed a crafted object in a session. (CVE-2016-0714) * A security manager bypass flaw was found in Tomcat that could allow remote, authenticated users to access arbitrary application data, potentially resulting in a denial of service. (CVE-2016-0763) * A denial of service vulnerability was identified in Commons FileUpload that occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file if the boundary was the typical tens of bytes long. (CVE-2016-3092) * A directory traversal flaw was found in Tomcat's RequestUtil.java. A remote, authenticated user could use this flaw to bypass intended SecurityManager restrictions and list a parent directory via a '/..' in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call. (CVE-2015-5174) * It was found that Tomcat could reveal the presence of a directory even when that directory was protected by a security constraint. A user could make a request to a directory via a URL not ending with a slash and, depending on whether Tomcat redirected that request, could confirm whether that directory existed. (CVE-2015-5345) * It was found that Tomcat allowed the StatusManagerServlet to be loaded by a web application when a security manager was configured. This allowed a web application to list all deployed web applications and expose sensitive information such as session IDs.

Description: Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. Security Fix(es): * It was reported that the Tomcat init script performed unsafe file handling, which could result in local privilege escalation. (CVE-2016-1240) * It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. (CVE-2016-6325) * The JmxRemoteLifecycleListener was not updated to take account of Oracle's fix for CVE-2016-3427. JMXRemoteLifecycleListener is only included in EWS 2.x and JWS 3.x source distributions. If you deploy a Tomcat instance built from source, using the EWS 2.x, or JWS 3.x distributions, an attacker could use this flaw to launch a remote code execution attack on your deployed instance. (CVE-2016-3092) * It was discovered that the code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other then their own. (CVE-2016-6816) * A bug was discovered in the error handling of the send file code for the NIO HTTP connector. This led to the current Processor object being added to the Processor cache multiple times allowing information leakage between requests including, and not limited to, session ID and the response body. (CVE-2016-8745) * The Realm implementations did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder. (CVE-2016-5018) * It was discovered that when a SecurityManager is configured Tomcat's system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible. (CVE-2016-6794) * It was discovered that a malicious web application could bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet. These packages provide a number of enhancements over the previous version of Red Hat JBoss Web Server. (JIRA#JWS-268) 4. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files).
