CWEhttps://cwe.mitre.org/data/definitions/732.html

The Device Mapper multipathing driver (aka multipath-tools or device-mapper-multipath) 0.4.8, as used in SUSE openSUSE, SUSE Linux Enterprise Server (SLES), Fedora, and possibly other operating systems, uses world-writable permissions for the socket file (aka /var/run/multipathd.sock), which allows local users to send arbitrary commands to the multipath daemon.

Weakness

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

Affected Software

Name Vendor Start Version End Version
Multipath-tools Christophe.varoqui 0.4.8 (including) 0.4.8 (including)
Red Hat Enterprise Linux 4 RedHat device-mapper-multipath-0:0.4.5-31.el4_7.1 *
Red Hat Enterprise Linux 5 RedHat device-mapper-multipath-0:0.4.7-23.el5_3.2 *
Multipath-tools Ubuntu upstream *

Potential Mitigations

  • Run the code in a “jail” or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
  • OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
