CVE-2013-1662 – VMware - Setuid VMware-mount Unsafe popen

https://notcve.org/view.php?id=CVE-2013-1662

vmware-mount in VMware Workstation 8.x and 9.x and VMware Player 4.x and 5.x, on systems based on Debian GNU/Linux, allows host OS users to gain host OS privileges via a crafted lsb_release binary in a directory in the PATH, related to use of the popen library function. vmware-mount en VMware Workstation v8.x y v9.x y VMware Player v4.x y v5.x, en sistemas basados en Debian GNU/Linux, permite a los usuarios del sistema operativo de host para obtener privilegios del sistema operativo de host manipulando la ruta del directorio del ejecutable lsb_release, relacionado con el uso de la librería de funciones popen. VMWare Workstation (up to and including 9.0.2 build-1031769) and Player have a setuid executable called vmware-mount that invokes lsb_release in the PATH with popen(3). Since PATH is user-controlled, and the default system shell on Debian-derived distributions does not drop privs, we can put an arbitrary payload in an executable called lsb_release and have vmware-mount happily execute it as root for us. • https://www.exploit-db.com/exploits/27938 https://www.exploit-db.com/exploits/40169 http://blog.cmpxchg8b.com/2013/08/security-debianisms.html http://www.vmware.com/security/advisories/VMSA-2013-0010.html • CWE-264: Permissions, Privileges, and Access Controls •
