UNKNOWN Summary
Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.34, and 7.x before 7.0.23 uses an inefficient approach for handling parameters, which allows remote attackers to cause a denial of service (CPU consumption) via a request that contains many parameters and parameter values, a different vulnerability than CVE-2011-4858.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2012-0680.NASL description Updated tomcat5 packages that fix multiple security issues and two bugs are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate 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. Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. JBoss Enterprise Web Server includes the Tomcat Native library, providing Apache Portable Runtime (APR) support for Tomcat. References in this text to APR refer to the Tomcat Native implementation, not any other apr package. This update includes bug fixes as documented in JBPAPP-4873 and JBPAPP-6133. It also resolves the following security issues : Multiple flaws were found in the way Tomcat handled HTTP DIGEST authentication. These flaws weakened the Tomcat HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064) A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor) and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ Protocol) connectors processed certain POST requests. An attacker could send a specially crafted request that would cause the connector to treat the message body as a new request. This allows arbitrary AJP messages to be injected, possibly allowing an attacker to bypass a web application last seen 2020-06-01 modified 2020-06-02 plugin id 78924 published 2014-11-08 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/78924 title RHEL 5 / 6 : JBoss Web Server (RHSA-2012:0680) NASL family Scientific Linux Local Security Checks NASL id SL_20120411_TOMCAT6_ON_SL6.NASL description Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause Tomcat to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit on the number of parameters processed per request to mitigate this issue. The default limit is 512 for parameters and 128 for headers. These defaults can be changed by setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties. (CVE-2011-4858) It was found that Tomcat did not handle large numbers of parameters and large parameter values efficiently. A remote attacker could make Tomcat use an excessive amount of CPU time by sending an HTTP request containing a large number of parameters or large parameter values.

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. JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise Application Platform. It provides a single deployment platform for the JavaServer Pages (JSP) and Java Servlet technologies. A flaw was found in the way JBoss Web handled UTF-8 surrogate pair characters. If JBoss Web was hosting an application with UTF-8 character encoding enabled, or that included user-supplied UTF-8 strings in a response, a remote attacker could use this flaw to cause a denial of service (infinite loop) on the JBoss Web server. (CVE-2011-4610) It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause JBoss Web to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit on the number of parameters and headers processed per request to mitigate this issue. The default limit is 512 for parameters and 128 for headers. These defaults can be changed by setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in last seen 2020-04-16 modified 2013-01-24 plugin id 64022 published 2013-01-24 reporter This script is Copyright (C) 2013-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/64022 title RHEL 5 / 6 : jbossweb (RHSA-2012:0074) NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2012-0474.NASL description Updated tomcat5 packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

(CVE-2011-4858) It was found that Tomcat did not handle large numbers of parameters and large parameter values efficiently. A remote attacker could make Tomcat use an excessive amount of CPU time by sending an HTTP request containing a large number of parameters or large parameter values. This update introduces limits on the number of parameters and headers processed per request to address this issue.

(CVE-2012-0022) Red Hat would like to thank oCERT for reporting CVE-2011-4858. oCERT acknowledges Julian Walde and Alexander Klink as the original reporters of CVE-2011-4858. Users of Tomcat should upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 58685 published 2012-04-12 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/58685 title CentOS 5 : tomcat5 (CESA-2012:0474) NASL family Mandriva Local Security Checks NASL id MANDRIVA_MDVSA-2012-085.NASL description A vulnerability has been discovered and corrected in tomcat5 : Apache Tomcat 5.5.x before 5.5.35, 6.x before 6.0.34, and 7.x before 7.0.23 uses an inefficient approach for handling parameters, which allows remote attackers to cause a denial of service (CPU consumption) via a request that contains many parameters and parameter values, a different vulnerability than CVE-2011-4858 (CVE-2012-0022).
