Privilege escalation in VMware products via Virtual-8086 mode #PF exception handling

IdentifiersCVE-2009-2267CWE-269

CVE-2009-2267 is a privilege-escalation vulnerability in multiple VMware virtualization products (Workstation, Player, ACE, Server, Fusion, ESXi, and ESX) when Virtual-8086 (v8086) mode is used. The hypervisor does not properly set the exception code when handling a guest page fault (#PF). A guest OS user can trigger the condition by supplying a crafted value for the CS (code segment) register, leading to incorrect exception semantics and enabling privilege gain within the guest OS.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A local user within a vulnerable guest OS can gain elevated privileges on that guest OS (i.e., guest-local privilege escalation) by triggering the malformed #PF exception handling in v8086 mode. No host escape or cross-VM impact is stated in the provided content.

Mitigation

If you can’t patch tonight, do this now.

Avoid or restrict use of Virtual-8086 mode in guests where feasible, and reduce exposure to untrusted code execution inside guest OS instances (since exploitation is guest-local). Primary mitigation is patching to the fixed VMware versions/builds listed.

Remediation

Patch, then assume compromise.

Upgrade to fixed VMware builds/versions:
  • VMware Workstation: 6.5.3 build 185404 or later
  • VMware Player: 2.5.3 build 185404 or later
  • VMware ACE: 2.5.3 build 185404 or later
  • VMware Server: 1.0.10 build 203137 or later; 2.0.2 build 203138 or later
  • VMware Fusion: 2.0.6 build 196839 or later For VMware ESXi/ESX, apply the vendor-provided updates that address CVE-2009-2267 (specific patch identifiers are not present in the provided content).
