For general information about signing drivers, see Driver Signing. An INF file also contains driver configuration information that SetupAPI stores in the registry, such as the driver's start type and load order group.įor more information about INF files and how they are created, see Creating an INF File and INF File Sections and Directives. The INF file is a text file that specifies the files that must be present for your driver to run and the source and destination directories for the driver files.
#COMODO FILESYSTEM FILTER DRIVER IS NOT LOADED INSTALL#
The installation process is controlled by INF files.Ī file system filter driver's INF file provides instructions that SetupAPI uses to install the driver. The Windows Setup and Device Installer Services, known collectively as SetupAPI, provide the functions that control Windows setup and driver installation.

Oct 22nd, 2019 - Comodo informed us that the official version (v12.) was released, with the release notes “Fixed: - Preventing unsigned DLLs from loading into CIS processes”.For optimal reliability and performance, use file system minifilter drivers with Filter Manager support instead of legacy file system filter drivers. RC is available for download and testing. Oct 22nd, 2019 - Comodo announced that Comodo Internet Security 2019 v12. Oct 20th, 2019 - We asked MITRE to issue a CVE.

That means that once the attacker drops a malicious DLL, the services will load the malicious code each time it is restarted.

The vulnerability gives an attacker the ability to load and execute malicious payloads in a persistent way, each time the services are loaded. This ability might be abused by an attacker for different purposes such as execution and evasion, for example: Application Whitelisting Bypass. The vulnerability gives attackers the ability to load and execute malicious payloads within the context of a COMODO signed process. Potential Malicious Uses and Impactīelow we show three possible ways that an attacker can leverage these vulnerabilities which we discovered and documented above.

Usually, AV products restrict any modification (such as writing, adding or modifying files) to their folders by using a mini-filter driver which enforces a read-only policy on all users (including Administrator).ĭespite this fact, we tried to implant a DLL, thinking “Who knows, it might even work…”. When started, cavwp.exe tries to load the missing iLog.dll library from its own directory. In our exploration, we targeted the cavwp.exe process which is a signed process and run as NT AUTHORITY\SYSTEM. Comodo Internet SecurityĬomodo Internet Security (CIS) is developed and distributed by Comodo Group, a free Internet security suite that includes an antivirus program, personal firewall, sandbox and a host-based intrusion prevention system (HIPS). Note: In order to exploit this vulnerability, the attacker needs to have Administrator privileges. In this post, we demonstrate how this vulnerability could have been used in order to achieve self-defense bypass, defense evasion, persistence and privilege escalation by loading an arbitrary unsigned DLL into a signed process that runs as NT AUTHORITY\SYSTEM.
