Arbitrary Code Execution

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Arbitrary Code Execution. When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

This is due to an incomplete fix for CVE-2017-12615.

  • M
Directory Traversal

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Directory Traversal. It allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory.

How to fix Directory Traversal?

Upgrade org.apache.tomcat:catalina to version 6.0.45 or higher.

  • M
Directory Traversal

org.apache.tomcat:catalina The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character.

[6,6.0.45)
  • M
Information Exposure

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Information Exposure. Apache Tomcat 6.0.30 through 6.0.33 and 7.x before 7.0.22 does not properly perform certain caching and recycling operations involving request objects, which allows remote attackers to obtain unintended read access to IP address and HTTP header information in opportunistic circumstances by reading TCP data.

[6.0.30,6.0.33]
  • M
Denial of Service (DoS)

org.apache.tomcat:catalina Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

[6,6.0.35)
  • H
Denial of Service (DoS)

org.apache.tomcat:catalina 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 (thread consumption) via a series of aborted upload attempts.

[6,6.0.44)
  • L
Directory Traversal

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Directory Traversal. When running within a SecurityManager, does not make the ServletContext attribute read-only, which allows local web applications to read or write files outside of the intended working directory, as demonstrated using a directory traversal attack.

How to fix Directory Traversal?

Upgrade org.apache.tomcat:catalina to version 6.0.53 or higher.

[6.0.13,6.0.53)
  • M
Arbitrary File Read

org.apache.tomcat:catalina java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

[6,6.0.40)
  • M
Arbitrary File Read

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Arbitrary File Read. Apache Tomcat before 6.0.40, 7.x before 7.0.54, and 8.x before 8.0.6 does not properly constrain the class loader that accesses the XML parser used with an XSLT stylesheet, which allows remote attackers to (1) read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue, or (2) read files associated with different web applications on a single Tomcat instance via a crafted web application.

How to fix Arbitrary File Read?

Upgrade org.apache.tomcat:catalina to version 6.0.40 or higher.

  • M
Cross-site Request Forgery (CSRF)

org.apache.tomcat:catalina 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.

[6,6.0.36)
  • M
Denial of Service (DoS)

org.apache.tomcat:catalina 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.

[6,6.0.34)
  • M
Access Restriction Bypass

org.apache.tomcat:catalina 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.

[6,6.0.36)
  • M
Access Restriction Bypass

org.apache.tomcat:catalina 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.

[6,6.0.36)
  • M
Improper Authentication

org.apache.tomcat:catalina 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.

[6,6.0.36)
  • M
Improper Authentication

org.apache.tomcat:catalina 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.

[6,6.0.36)
  • M
Improper Authentication

org.apache.tomcat:catalina 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 request into a session by sending this request during completion of the login form, a variant of a session fixation attack.

[6.0.21,6.0.36]
  • M
Information Exposure

org.apache.tomcat:catalina 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 conjunction with an entity reference, related to an XML External Entity (XXE) issue.

[6,6.0.39)
  • M
Improper Input Validation

org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Improper Input Validation. The org/apache/catalina/connector/CoyoteAdapter.java in Apache Tomcat 6.0.33 through 6.0.37 does not consider the disableURLRewriting setting when handling a session ID in a URL, which allows remote attackers to conduct session fixation attacks via a crafted URL.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:catalina to version 6.0.38 or higher.
