Summary

mount.cifs in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8 and 3.4 before 3.4.2, when mount.cifs is installed suid root, does not properly enforce permissions, which allows local users to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or -v option.

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.

(CVE-2009-0798) - A security bypass vulnerability exists in Samba in the acl_group_override() function when dos filemode is enabled. A remote attacker can exploit this to modify access control lists for files via vectors related to read access to uninitialized memory. (CVE-2009-1888) - A security bypass vulnerability exists in Samba in the SMB subsystem due to improper handling of errors when resolving pathnames. An authenticated, remote attacker can exploit this to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories. (CVE-2009-2813) - A denial of service vulnerability exists in Samba that allows authenticated, remote attackers to cause an infinite loop via an unanticipated oplock break notification reply packet. (CVE-2009-2906) - An information disclosure vulnerability exists in Samba in mount.cifs due to improper enforcement of permissions. A local attacker can exploit this to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or -v option. (CVE-2009-2948)

    descriptionSeveral vulnerabilities have been discovered in samba, an implementation of the SMB/CIFS protocol for Unix systems, providing support for cross-platform file and printer sharing with other operating systems and more. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-2948 The mount.cifs utility is missing proper checks for file permissions when used in verbose mode. This allows local users to partly disclose the content of arbitrary files by specifying the file as credentials file and attempting to mount a samba share. - CVE-2009-2906 A reply to an oplock break notification which samba doesn

    descriptionFrom Red Hat Security Advisory 2009:1529 : Updated samba packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. Samba is a suite of programs used by machines to share files, printers, and other information. A denial of service flaw was found in the Samba smbd daemon. An authenticated, remote user could send a specially crafted response that would cause an smbd child process to enter an infinite loop. An authenticated, remote user could use this flaw to exhaust system resources by opening multiple CIFS sessions.

    descriptionMultiple vulnerabilities has been found and corrected in samba : The SMB (aka Samba) subsystem in Apple Mac OS X 10.5.8, when Windows File Sharing is enabled, does not properly handle errors in resolving pathnames, which allows remote authenticated users to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories (CVE-2009-2813). smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break notification reply packet (CVE-2009-2906). mount.cifs in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8 and 3.4 before 3.4.2, when mount.cifs is installed suid root, does not properly enforce permissions, which allows local users to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or -v option (CVE-2009-2948). The versions of samba shipping with Mandriva Linux CS4/MES5/2008.1/2009.0/2009.1 have been updated to the latest version that includes the fixes for these issues. Additionally for 2009.1 the version upgrade provides many upstream bug fixes such as improved Windows(tm) 7 support. The version for CS3 has been patched to address these security issues.

    descriptionJ. David Hester discovered that Samba incorrectly handled users that lack home directories when the automated [homes] share is enabled. An authenticated user could connect to that share name and gain access to the whole filesystem. (CVE-2009-2813) Tim Prouty discovered that the smbd daemon in Samba incorrectly handled certain unexpected network replies. A remote attacker could send malicious replies to the server and cause smbd to use all available CPU, leading to a denial of service. (CVE-2009-2906) Ronald Volgers discovered that the mount.cifs utility, when installed as a setuid program, would not verify user permissions before opening a credentials file. A local user could exploit this to use or read the contents of unauthorized credential files. (CVE-2009-2948) Reinhard Nissl discovered that the smbclient utility contained format string vulnerabilities in its file name handling. Because of security features in Ubuntu, exploitation of this vulnerability is limited. If a user or automated system were tricked into processing a specially crafted file name, smbclient could be made to crash, possibly leading to a denial of service. This only affected Ubuntu 8.10. (CVE-2009-1886) Jeremy Allison discovered that the smbd daemon in Samba incorrectly handled permissions to modify access control lists when dos filemode is enabled. A remote attacker could exploit this to modify access control lists. This only affected Ubuntu 8.10 and Ubuntu 9.04. (CVE-2009-1886). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
