CVE-2022-34008

CWE-269
 
 
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.

CVE-2019-14694

CWE-416
 
 
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.

CVE-2019-14270

CWE-254
 
 
Comodo Antivirus through 12.0.0.6870, Comodo Firewall through 12.0.0.6870, and Comodo Internet Security Premium through 12.0.0.6870, with the Comodo Container feature, are vulnerable to Sandbox Escape.

CVE-2019-3973

CWE-787
 
 
Comodo Antivirus versions 11.0.0.6582 and below are vulnerable to Denial of Service affecting CmdGuard.sys via its filter port "cmdServicePort". A low privileged process can crash CmdVirth.exe to decrease the port's connection count followed by process hollowing a CmdVirth.exe instance with malicious code to obtain a handle to "cmdServicePort". Once this occurs, a specially crafted message can be sent to "cmdServicePort" using "FilterSendMessage" API. This can trigger an out-of-bounds write if lpOutBuffer parameter in FilterSendMessage API is near the end of specified buffer bounds. The crash occurs when the driver performs a memset operation which uses a size beyond the size of buffer specified, causing kernel crash.

 
 
CVE-2019-3972

CWE-125
 
 
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.

 
 
CVE-2019-3971

CWE-119
 
 
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.

 
 
CVE-2019-3970

CWE-20
 
 
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.

 
 
CVE-2019-3969

CWE-264
 
 
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.
