DescriptionEpFwNDIS.sys Trusted Value Vulnerability
NotesRepeatability: Infinite
Notes:
This module exploits a vulnerability on the ESET Personal Firewall NDIS filter (EpFwNdis.sys) driver.
The Firewall Module Build 1183 (20140214) and earlier in ESET Smart Security and ESET Endpoint Security
products 5.0 through 7.0 are the vulnerable ones.
While processing the input buffer inside the IOCTL 0x830020CC a trusted value condition occurs. The
correct value could be obtained through another IOCTL which has an information leak. Once the correct
value is known a NULL page dereference could be achieved.
