BACKGROUND\r\n\r\nThe Novell Client software provides a workstation with access to Novell\r\nNetWare networks as well as Novell Open Enterprise Server &#40;OES&#41;\r\nservices. Novell Clients can access the full range of Novell services\r\nsuch as authentication via Novell eDirectory, network browsing and\r\nservice resolution, and secure and reliable file system access. More\r\ninformation about the Novel Client can be found on the vendor&#39;s site at\r\nthe following URL.\r\n\r\nhttp://www.novell.com/products/clients/\r\n\r\nII. DESCRIPTION\r\n\r\nLocal exploitation of an input validation error vulnerability within\r\nNovell NetWare Client could allow an unprivileged attacker to execute\r\narbitrary code within the kernel.\r\n\r\nWhen the Novell NetWare Client is installed on a Windows based operating\r\nsystem, the driver nwfilter.sys will be loaded at system startup. This\r\ndriver allows any user to open the device &quot;&#92;.&#92;nwfilter&quot; and issue\r\nIOCTLs with a buffering mode of METHOD_NEITHER.\r\n\r\nThe problem specifically exists because the driver allows untrusted user\r\nmode code to pass kernel addresses as arguments to the driver. With\r\nspecially constructed input, a malicious user can use functionality\r\nwithin the driver to patch kernel addresses and execute arbitrary code\r\nwithin kernel mode.\r\n\r\nIII. ANALYSIS\r\n\r\nExploitation of this vulnerability allows an unprivileged local user to\r\npatch and execute arbitrary code within the kernel. In order to exploit\r\nthe vulnerability, an attacker needs to be able to log in to the target\r\nmachine and execute a specially crafted executable.\r\n\r\nIV. DETECTION\r\n\r\niDefense has confirmed the existence of this vulnerability in\r\nnwfilter.sys, file version 4.91.1.1, as included with Novell&#39;s NetWare\r\nClient 4.91 SP4. Other versions are suspected vulnerable as well.\r\n\r\nV. WORKAROUND\r\n\r\niDefense is currently unaware of any workaround for this issue.\r\n\r\nVI. VENDOR RESPONSE\r\n\r\nNovell has addressed this vulnerability by releasing patches that remove\r\nthe &quot;nwfilter.sys&quot; driver. For more information, consult Novell&#39;s\r\nadvisory at the following URL.\r\n\r\nhttps://secure-support.novell.com/KanisaPlatform/Publishing/98/3260263_f.SAL_Public.html\r\n\r\nVII. CVE INFORMATION\r\n\r\nThe Common Vulnerabilities and Exposures &#40;CVE&#41; project has assigned the\r\nname CVE-2007-5667 to this issue. This is a candidate for inclusion in\r\nthe CVE list &#40;http://cve.mitre.org/&#41;, which standardizes names for\r\nsecurity problems.\r\n\r\nVIII.
