Summary

Apache Axis2 before 1.5.2, as used in IBM WebSphere Application Server (WAS) 7.0 through 7.0.0.12, IBM Feature Pack for Web Services 6.1.0.9 through 6.1.0.32, IBM Feature Pack for Web 2.0 1.0.1.0, Apache Synapse, Apache ODE, Apache Tuscany, Apache Geronimo, and other products, does not properly reject DTDs in SOAP messages, which allows remote attackers to read arbitrary files, send HTTP requests to intranet servers, or cause a denial of service (CPU and memory consumption) via a crafted DTD, as demonstrated by an entity declaration in a request to the Synapse SimpleStockQuoteService.

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.

descriptionBUGTRAQ ID: 40976 CVE ID: CVE-2010-1632 Axis2是一个Web服务的核心支援引擎。 根据SOAP 1.1规范的规定,SOAP消息总不能包含有文档类型声明(DTD)。在Axis2中,是通过StAXSOAPModelBuilder类来实现这个限制的。这个方法存在两个问题: 1 仅适用于SOAP绑定,而支持纯XML消息的HTTP绑定仍允许请求消息中存在DTD。 2 在处理带有DTD的文档时,StAXSOAPModelBuilder仅在从StAX解析器接收到DTD事件后才会报告错误,而这时StAX解析器可能已经处理或部分处理了DTD。 这说明Axis2受基于DTD的XML攻击的影响。有两种类型的攻击: * DTD可能引用其他的文档,也就是内部子集中所声明的DTD或外部实体。如果对XML解析器配置了默认的实体解析器(在本文所述情况下为Axis2),就会允许攻击者要求解析器访问任意文件。由于可能将URL用作系统ID,这包括仅可在服务器所部署的网络中访问的远程资源。 * 尽管XML不允许递归实体定义,但允许嵌套的实体定义。如果文档中包含有深度嵌套的实体定义,解析该文档就会在实体展开期间导致非常高的CPU和内存消耗。 IBM Websphere Application Server 7.0 IBM Websphere Application Server 6.1 Apache Group Axis2 1.5.1 Apache Group Axis2 1.4.1 临时解决方法: * 禁用对application/xml内容类型的支持,使用SOAPBuilder替换ApplicationXMLBuilder: &lt;messageBuilder contentType=&quot;application/xml&quot; class=&quot;org.apache.axis2.builder.SOAPBuilder&quot;/&gt; 厂商补丁: Apache Group ------------ 目前厂商已经发布了升级补丁以修复这个安全问题,请到厂商的主页下载: https://issues.apache.org/jira/browse/AXIS2-4450 IBM --- 目前厂商已经发布了升级补丁以修复这个安全问题,请到厂商的主页下载: http://www-01.ibm.com/support/docview.wss?uid=swg21433581
