Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

descriptionThis module exploits CVE-2016-0792 a vulnerability in Jenkins versions older than 1.650 and Jenkins LTS versions older than 1.642.2 which is caused by unsafe deserialization in XStream with Groovy in the classpath, which allows remote arbitrary code execution. The issue affects default installations. Authentication is not required to exploit the vulnerability.

Jenkins is a continuous integration server that monitors executions of
repeated jobs, such as building a software project or jobs run by
cron.

Security Fix(es) :

The Jenkins continuous integration server has been updated to upstream
version 1.642.2 LTS that addresses a large number of security issues,
including XSS, CSRF, information disclosure, and code execution.

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-2016-0792, CVE-2016-3721, CVE-2016-3722, CVE-2016-3723,
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/

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.

    this to open a JRMP listener on the server hosting the
    Jenkins master process, allowing the execution of
    arbitrary code. (CVE-2016-0788)

    to improper sanitization of CRLF sequences, which are
    passed via CLI command names, before they are included

    descriptionThe Jenkins web server running on the remote host is affected by a remote code execution vulnerability due to unsafe deserialize calls of unauthenticated Java objects to the Groovy library, specifically the runtime.MethodClosure class. An unauthenticated, remote attacker can exploit this, via a crafted XML file, to execute arbitrary code on the target host.

    descriptionXstream 的反序列化漏洞的根源就是 Groovy 组件的问题(参考 [Apache Groovy MethodClosure 远程代码执行漏洞（CVE-2015-3253）](https://www.seebug.org/vuldb/ssvid-90854))，只不过在 Xstream 中进行反序列化时恰好有触发存在缺陷函数的点，也就是 Xstream 在反序列化时调用了 `Map#put` 函数将构造好的 `Expando` 实例作为 key 添加到集合中时触发了代码执行，如下图: ![](https://images.seebug.org/1456914460246) 这里的 key 就是我们构造的 `Expando` 的实例对象。 在构造 EXP 时，首先我们要构造一个 `Expando` 的一个对象实例，同时设置 `hashCode` 的实现为 `MethodClosure` 的实例，然后实例化一个 `HashMap` 对象调用 `put` 方法将 `Expando` 的实例化对象作为 key，value 任意添加到 map 中，然后让 Xstream 对 map 进行序列化，这样我们的 Payload 就 OK 了。 估计有很多人不明白漏洞作者博客的 POC 是怎么来的，这里的序列化是基于 xml 的，所以得借助 Xstream 相关函数将构造好的对象进行序列化然后生成 xml，反序列化时解析 xml，转换成相关对象。 好人做到底，我就把POC的生成代码也发出来吧: ![](https://images.seebug.org/1456914467214) 执行程序后，我们的POC就生成成功，如下图所示: ![](https://images.seebug.org/1456914471951) 至于怎么执行其他的代码，这个还比较麻烦，除了执行命令之外，好像没有什么好的办法，因为 `MethodClosure` 的构造函数中指定了要执行方法的对象以及执行的方法名称，所以说只能调用一次构造函数，并且有一个无参数的方法可以执行，这样才能实现函数的正常运行。 ### 来源与参考 * [Apache Groovy MethodClosure 远程代码执行漏洞（CVE-2015-3253）](https://www.seebug.org/vuldb/ssvid-90854) * [Xstream Deserializable Vulnerablity And Groovy(CVE-2015-3253)](http://drops.wooyun.org/papers/13243) * [RCE via XStream object deserialization](http://www.pwntester.com/blog/2013/12/23/rce-via-xstream-object-deserialization38/) * [Serialization Must Die: Act 2: XStream (Jenkins CVE-2016-0792)](https://www.contrastsecurity.com/security-influencers/serialization-must-die-act-2-xstream?platform=hootsuite)
