Summary

The configtest function in the Red Hat dhcpd init script for DHCP 3.0.1 in Red Hat Enterprise Linux (RHEL) 3 allows local users to overwrite arbitrary files via a symlink attack on an unspecified temporary file, related to the "dhcpd -t" command.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Symlink Attack
    An attacker positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name. The endpoint file may be either output or input. If the file is output, the result is that the endpoint is modified, instead of a file at the intended location. Modifications to the endpoint file may include appending, overwriting, corrupting, changing permissions, or other modifications. In some variants of this attack the attacker may be able to control the change to a file while in other cases they cannot. The former is especially damaging since the attacker may be able to grant themselves increased privileges or insert false information, but the latter can also be damaging as it can expose sensitive information or corrupt or destroy vital system or application files. Alternatively, the endpoint file may serve as input to the targeted application. This can be used to feed malformed input into the target or to cause the target to process different information, possibly allowing the attacker to control the actions of the target or to cause the target to expose information to the attacker. Moreover, the actions taken on the endpoint file are undertaken with the permissions of the targeted user or application, which may exceed the permissions that the attacker would normally have.
  • 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.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

"a. Service Console update for DHCP and third-party library update
   for DHCP client.

   DHCP is an Internet-standard protocol by which a computer can be
   connected to a local network, ask to be given configuration
   information, and receive from a server enough information to
   configure itself as a member of that network.

   A stack-based buffer overflow in the script_write_params method in
   ISC DHCP dhclient allows remote DHCP servers to execute arbitrary
   code via a crafted subnet-mask option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-0692 to this issue.

   An insecure temporary file use flaw was discovered in the DHCP
   daemon's init script ('/etc/init.d/dhcpd'). A local attacker could
   use this flaw to overwrite an arbitrary file with the output of the
   'dhcpd -t' command via a symbolic link attack, if a system
   administrator executed the DHCP init script with the 'configtest',
   'restart', or 'reload' option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-1893 to this issue.

   Service Console package kernel update to version
   kernel-2.4.21-58.EL.

   security issues fixed in kernel-2.4.21-58.EL

c. JRE Security Update

   JRE update to version 1.5.0_18, which addresses multiple security

"From Red Hat Security Advisory 2009:1154 :

Updated dhcp packages that fix two security issues are now available
for Red Hat Enterprise Linux 3.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

The Dynamic Host Configuration Protocol (DHCP) is a protocol that
allows individual devices on an IP network to get their own network
configuration information, including an IP address, a subnet mask, and
a broadcast address.

The Mandriva Linux Engineering Team discovered a stack-based buffer
overflow flaw in the ISC DHCP client. If the DHCP client were to
receive a malicious DHCP response, it could crash or execute arbitrary
code with the permissions of the client (root). (CVE-2009-0692)

An insecure temporary file use flaw was discovered in the DHCP
daemon's init script ('/etc/init.d/dhcpd'). A local attacker could use
this flaw to overwrite an arbitrary file with the output of the 'dhcpd
-t' command via a symbolic link attack, if a system administrator
executed the DHCP init script with the 'configtest', 'restart', or
'reload' option. (CVE-2009-1893)

Users of DHCP should upgrade to these updated packages, which contain
backported patches to correct these issues."
