Summary

Jenkins before 1.650 and LTS before 1.642.2 do not use a constant-time algorithm to verify CSRF tokens, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force approach.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

OpenShift Enterprise by Red Hat is the company's cloud computing
Platform-as-a-Service (PaaS) solution designed for on-premise or
private cloud deployments.

* The Jenkins continuous integration server has been updated to
upstream version 1.651.2 LTS that addresses a large number of security
issues, including open redirects, a potential denial of service,
unsafe handling of user provided environment variables and several
instances of sensitive information disclosure. (CVE-2014-3577,
CVE-2016-0788, CVE-2016-0789, CVE-2016-0790, CVE-2016-0791,

CVE-2016-3724, CVE-2016-3725, CVE-2016-3726, CVE-2016-3727,
CVE-2015-7501)

Space precludes documenting all of the bug fixes and enhancements in
this advisory. See the OpenShift Enterprise Technical Notes, which
will be updated shortly for release 2.2.10, for details about these
changes :

https://access.redhat.com/documentation/en-US/OpenShift_Enterprise/2/
html-single/Technical_Notes/index.html

All OpenShift Enterprise 2 users are advised to upgrade to these
updated packages."

    descriptionThe remote web server hosts a version of Jenkins that is prior to 1.650, or a version of Jenkins LTS prior to 1.642.2; or else a version of Jenkins Enterprise that is 1.642.x.y prior to 1.642.2.1, 1.625.x.y prior to 1.625.16.1, or 1.609.x.y prior to 1.609.16.1. It is, therefore, affected by the following vulnerabilities : - An unspecified flaw exists in the Jenkins remoting module. An unauthenticated, remote attacker can exploit this to open a JRMP listener on the server hosting the Jenkins master process, allowing the execution of arbitrary code. (CVE-2016-0788) - A flaw exists in main/java/hudson/cli/CLIAction.java due to improper sanitization of CRLF sequences, which are passed via CLI command names, before they are included in HTTP responses. An unauthenticated, remote attacker can exploit this, via crafted Jenkins URLs, to carry out an HTTP response splitting attack. (CVE-2016-0789) - The verification of user-supplied API tokens fails to use a constant-time comparison algorithm. An unauthenticated, remote attacker can exploit this, via statistical methods, to determine valid API tokens, thus facilitating a brute-force attack to gain access to user credentials. (CVE-2016-0790) - The verification of user-supplied XSRF crumbs fails to use a constant-time comparison algorithm. An unauthenticated, remote attacker can exploit this, via statistical methods, to determine valid XSRF crumbs, thus facilitating a brute-force attack to bypass the cross-site request forgery protection mechanisms. (CVE-2016-0791) - A flaw exists in groovy.runtime.MethodClosure class due to unsafe deserialize calls of unauthenticated Java objects to the Commons Collections library. An authenticated, remote attacker can exploit this, by posting a crafted XML file to certain API endpoints, to execute arbitrary code. (CVE-2016-0792)

prior to 1.625.16.1, or 1.609.x.y prior to 1.609.16.1. It is,
therefore, affected by the following vulnerabilities :

  - An unspecified flaw exists in the Jenkins remoting
    module. An unauthenticated, remote attacker can exploit
    this to open a JRMP listener on the server hosting the
    Jenkins master process, allowing the execution of
    arbitrary code. (CVE-2016-0788)

  - A flaw exists in main/java/hudson/cli/CLIAction.java due
    to improper sanitization of CRLF sequences, which are
    passed via CLI command names, before they are included
    in HTTP responses. An unauthenticated, remote attacker
    can exploit this, via crafted Jenkins URLs, to carry out
    an HTTP response splitting attack. (CVE-2016-0789)

  - The verification of user-supplied API tokens fails to
    use a constant-time comparison algorithm. An
    unauthenticated, remote attacker can exploit this, via
    statistical methods, to determine valid API tokens,
    thus facilitating a brute-force attack to gain access
    to user credentials. (CVE-2016-0790)

  - The verification of user-supplied XSRF crumbs fails to
    use a constant-time comparison algorithm. An
    unauthenticated, remote attacker can exploit this, via
    statistical methods, to determine valid XSRF crumbs,
    thus facilitating a brute-force attack to bypass the
    cross-site request forgery protection mechanisms.
    (CVE-2016-0791)

  - A flaw exists in groovy.runtime.MethodClosure class due
    to unsafe deserialize calls of unauthenticated Java
    objects to the Commons Collections library. An
    authenticated, remote attacker can exploit this, by
    posting a crafted XML file to certain API endpoints, to
    execute arbitrary code. (CVE-2016-0792)");
