    description According to its self-reported version number, the instance of Apache Tomcat 6.0 listening on the remote host is prior to Tomcat 6.0.36. It is, therefore, affected by multiple vulnerabilities : - A flaw exists within the parseHeaders() function that allows for a crafted header to cause a remote denial of service. (CVE-2012-2733) - An error exists related to FORM authentication that allows a security bypass if 'j_security_check' is appended to the request. (CVE-2012-3546) - An error exists in the file 'filters/CsrfPreventionFilter.java' that allows cross-site request forgery (XSRF) attacks to bypass the filtering. This can allow access to protected resources without a session identifier. (CVE-2012-4431) - An error exists related to the 'NIO' connector when HTTPS and 'sendfile' are enabled that can force the application into an infinite loop. (CVE-2012-4534) - Replay-countermeasure functionality in HTTP Digest Access Authentication tracks cnonce values instead of nonce values, which makes it easier for attackers to bypass access restrictions by sniffing the network for valid requests. (CVE-2012-5885) - The HTTP Digest Access Authentication implementation caches information about the authenticated user, which allows an attacker to bypass authentication via session ID. (CVE-2012-5886) - The HTTP Digest Access Authentication implementation does not properly check for stale nonce values with enforcement of proper credentials, which allows an attacker to bypass restrictions by sniffing requests. (CVE-2012-5887) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    description Updated tomcat6 packages that fix multiple security issues are now available for JBoss Enterprise Web Server 2.0.0 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. It was found that sending a request without a session identifier to a protected resource could bypass the Cross-Site Request Forgery (CSRF) prevention filter. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter and do not contain internal mitigation for CSRF. (CVE-2012-4431) A flaw was found in the way Tomcat handled sendfile operations when using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote attacker could use this flaw to cause a denial of service (infinite loop). The HTTP NIO connector is used by default in JBoss Enterprise Web Server. The Apache Portable Runtime (APR) connector from the Tomcat Native library was not affected by this flaw. (CVE-2012-4534) Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887) A denial of service flaw was found in the way the Tomcat HTTP NIO connector enforced limits on the permitted size of request headers. A remote attacker could use this flaw to trigger an OutOfMemoryError by sending a specially crafted request with very large headers. The HTTP NIO connector is used by default in JBoss Enterprise Web Server. The APR connector from the Tomcat Native library was not affected by this flaw. (CVE-2012-2733) Warning: Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files). Users of Tomcat should upgrade to these updated packages, which resolve these issues. Tomcat must be restarted for this update to take effect.

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. It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending '/j_security_check' to the end of a URL.

    NASL id REDHAT-RHSA-2013-0623.NASL
    description Updated tomcat6 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 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. Apache Tomcat is a servlet container. It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending '/j_security_check' to the end of a URL. A remote attacker with an authenticated session on an affected application could use this flaw to circumvent authorization controls, and thereby access resources not permitted by the roles associated with their authenticated session. (CVE-2012-3546) A flaw was found in the way Tomcat handled sendfile operations when using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote attacker could use this flaw to cause a denial of service (infinite loop). The HTTP blocking IO (BIO) connector, which is not vulnerable to this issue, is used by default in Red Hat Enterprise Linux 6. (CVE-2012-4534) Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887) Users of Tomcat should upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect.

  • NASL family Solaris Local Security Checks
    NASL id SOLARIS11_TOMCAT_20140401.NASL
    description The remote Solaris system is missing necessary patches to address security updates : - java/org/apache/coyote/http11/InternalNioInputBuffer.jav a 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 header data. (CVE-2012-2733) - 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 /j_security_check at the end of a URI. (CVE-2012-3546) - 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. (CVE-2012-4431) - org/apache/tomcat/util/net/NioEndpoint.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, when the NIO connector is used in conjunction with sendfile and HTTPS, allows remote attackers to cause a denial of service (infinite loop) by terminating the connection during the reading of a response. (CVE-2012-4534) - 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 easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, a different vulnerability than CVE-2011-1184. (CVE-2012-5885) - 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 caches information about the authenticated user within the session state, which makes it easier for remote attackers to bypass authentication via vectors related to the session ID. (CVE-2012-5886) - 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 does not properly check for stale nonce values in conjunction with enforcement of proper credentials, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests. (CVE-2012-5887)
