Comodo: Security Vulnerabilities
Comodo Internet Security Pro Directory Traversal Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Comodo Internet Security Pro. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the update mechanism. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-19055.

Comodo Antivirus 12.2.2.8012 has a quarantine flaw that allows privilege escalation. To escalate privilege, a low-privileged attacker can use an NTFS directory junction to restore a malicious DLL from quarantine into the System32 folder.

An issue was discovered in signmgr.dll 6.5.0.819 in Comodo Internet Security through 12.0. A DLL Preloading vulnerability allows an attacker to implant an unsigned DLL named iLog.dll in a partially unprotected product directory. This DLL is then loaded into a high-privileged service before the binary signature validation logic is loaded, and might bypass some of the self-defense mechanisms.

A use-after-free flaw in the sandbox container implemented in cmdguard.sys in Comodo Antivirus 12.0.0.6870 can be triggered due to a race condition when handling IRP_MJ_CLEANUP requests in the minifilter for directory change notifications. This allows an attacker to cause a denial of service (BSOD) when an executable is run inside the container.

Comodo Antivirus versions up to 12.0.0.6810 are vulnerable to Local Privilege Escalation due to CmdAgent's handling of COM clients. A local process can bypass the signature check enforced by CmdAgent via process hollowing which can then allow the process to invoke sensitive COM methods in CmdAgent such as writing to the registry with SYSTEM privileges.

Comodo Antivirus versions up to 12.0.0.6810 are vulnerable to Arbitrary File Write due to Cavwp.exe handling of Comodo's Antivirus database. Cavwp.exe loads Comodo antivirus definition database in unsecured global section objects, allowing a local low privileged process to modify this data directly and change virus signatures.

Comodo Antivirus versions up to 12.0.0.6810 are vulnerable to a local Denial of Service affecting CmdVirth.exe via its LPC port "cmdvrtLPCServerPort". A low privileged local process can connect to this port and send an LPC_DATAGRAM, which triggers an Access Violation due to hardcoded NULLs used for Source parameter in a memcpy operation that is called for this handler. This results in CmdVirth.exe and its child svchost.exe instances to terminate.

Comodo Antivirus versions 12.0.0.6810 and below are vulnerable to Denial of Service affecting CmdAgent.exe via an unprotected section object "<GUID>_CisSharedMemBuff". This section object is exposed by CmdAgent and contains a SharedMemoryDictionary object, which allows a low privileged process to modify the object data causing CmdAgent.exe to crash.
