Windows service and uninstall paths are not quoted when BIND is installed
- Published
- Updated
- Reserved
- Assigned by
- isc
Description
The BIND installer on Windows uses an unquoted service path which can enable a local user to achieve privilege escalation if the host file system permissions allow this. Affects BIND 9.2.6-P2->9.2.9, 9.3.2-P1->9.3.6, 9.4.0->9.8.8, 9.9.0->9.9.10, 9.10.0->9.10.5, 9.11.0->9.11.1, 9.9.3-S1->9.9.10-S1, 9.10.5-S1.

Weakness
- This vulnerability exists in the installer delivered with BIND for Windows and not within BIND itself. Non-Windows builds and installations are unaffected. A manual installation of BIND where the service path is quoted when added would not be at risk.

Affected products
ISC · BIND 9
- affected 9.2.6-P2->9.2.9, 9.3.2-P1->9.3.6, 9.4.0->9.8.8, 9.9.0->9.9.10, 9.10.0->9.10.5, 9.11.0->9.11.1, 9.9.3-S1->9.9.10-S1, 9.10.5-S1
What to do
Solution: Upgrade to the patched release most closely related to your current version of BIND. These can all be downloaded from http://www.isc.org/downloads. BIND 9 version 9.9.10-P1 BIND 9 version 9.10.5-P1 BIND 9 version 9.11.1-P1 BIND Supported Preview Edition is a special feature preview branch of BIND provided to eligible ISC support customers. BIND 9 version 9.9.10-S2 BIND 9 version 9.10.5-S2
Workaround: BIND installations on Windows are not at risk if the host file permissions prevent creation of a binary in a location where the service executor would run it instead of named.exe.
Exploitation: No known active exploits but this generic weakness is already a well-known attack vector if user file access permissions do not adequately prevent the installation of malicious executables.
