Summary

rxvt 2.6.4 opens a terminal window on :0 if the DISPLAY environment variable is not set, which might allow local users to hijack X11 connections. NOTE: it was later reported that rxvt-unicode, mrxvt, aterm, multi-aterm, and wterm are also affected. NOTE: realistic attack scenarios require that the victim enters a command on the wrong machine.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

descriptionCVE ID：CVE-2008-1142 CVE-2008-1692 CNCVE ID：CNCVE-20081142 CNCVE-20081692 rxvt(ouR eXtended Virtual Terminal)是一款X窗口系统的终端模拟器。 rxvt存在安全问题，本地攻击者可以利用漏洞提升特权。 rxvt如果没有通过指定-display选项，并缺少DISPLAY环境变量的情况下，就会使用:0作为X11显示，这可导致本地用户劫持X11会话，通过恶意的X服务器以运行rxvt用户的进程权限执行任意命令。 rxvt-unicode、mrxvt、aterm、multi-aterm、wterm等终端也受影响。 rxvt rxvt 2.6.4 Eterm Eterm 0.9.4 厂商解决方案 Gentoo提供如下安全公告(GLSA-200805-03)以及相应补丁: <a href=http://security.gentoo.org/glsa/glsa-200805-03.xml target=_blank>http://security.gentoo.org/glsa/glsa-200805-03.xml</a> 所有aterm用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/aterm-1.0.1-r1&quot; 所有Eterm用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/eterm-0.9.4-r1&quot; 所有Mrxvt用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/mrxvt-0.5.3-r2&quot; 所有multi-aterm用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/multi-aterm-0.2.1-r=1&quot; 所有RXVT用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/rxvt-2.7.10-r4&quot; 所有rxvt-unicode用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/rxvt-unicode-9.02-r=1&quot; 所有wterm用户都应升级到最新版本： # emerge --sync # emerge --ask --oneshot --verbose &quot;&gt;=3Dx11-terms/wterm-6.2.9-r3&quot;
