Multiple VMware products shared folder directory traversal
| vmware-sharedfolders-directory-traversal (40837) |  Medium Risk |
Description:
Multiple VMware products could allow a local attacker to traverse directories on the system. If a host-to-guest shared folder is enabled, an attacker could send a specially-crafted multibyte string containing "dot dot" sequences (%c0%2e%c0%2e) to view and write arbitrary files on the host system.
Platforms Affected:
- VMware, ACE 1.0
- VMware, ACE 1.0.2
- VMware, ACE 2.0
- VMware, ACE 2.0.1
- VMware, ACE 2.0.2
- VMware, Player 1.0.1_build_19317
- VMware, Player 1.0.2
- VMware, Player 1.0.3
- VMware, Player 1.0.4
- VMware, Workstation 4.5.2
- VMware, Workstation 5.5.3_build_34685
- VMware, Workstation 5.5.4
- VMware, Workstation 6.0
- VMware, Workstation 6.0.1
- VMware, Workstation 6.0.2

(dot dot) sequences, which bypasses the protection mechanism, as demonstrated using a %c0%2e%c0%2e string.
