Summary

vsdatant.sys 6.5.737.0 in Check Point Zone Labs ZoneAlarm before 7.0.362 allows local users to gain privileges via a crafted Interrupt Request Packet (Irp) in a METHOD_NEITHER (1) IOCTL 0x8400000F or (2) IOCTL 0x84000013 request, which can be used to overwrite arbitrary memory locations.

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: 25365 CVE(CAN) ID: CVE-2007-4216,CVE-2005-2932 ZoneAlarm是一款个人电脑防火墙,能保护个人数据和隐私安全。 ZoneAlarm的实现和安装上存在多个安全漏洞,本地攻击者可能利用此漏洞提升自己的权限。 ZoneAlarm产品vsdatant.sys设备驱动的IOCTL处理代码没有验证传送给IOCTL 0x8400000F和IOCTL 0x84000013的用户域提供的地址。由于没有正确地验证IRQ参数,攻击者可以利用这些IOCTL使用常数双字值0x60001或ZwQuerySystemInformation返回的缓冲区内容覆盖任意内存,包括内核内存及所运行进程的代码段。 ZoneAlarm产品在安装期间没有设置安全的默认访问控制列表(ACL)。如果管理员安装了任何ZoneAlarm工具的话,默认的ACL允许任意用户修改所安装的文件。由于有些程序是以系统服务运行的,因此攻击者可以使用自己的代码替换所安装的ZoneAlarm文件,之后代码会以系统级权限执行 Zone Labs ZoneAlarm Security Suite 6.5.737 Zone Labs ZoneAlarm Security Suite 5.5.062.004 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: <a href="http://www.zonealarm.com/store/content/catalog/products/trial_zaFamily/trial_zaFamily.jsp" target="_blank">http://www.zonealarm.com/store/content/catalog/products/trial_zaFamily/trial_zaFamily.jsp</a>
