Vulnerabilities

Comodo Dome Firewall 2.7.0 contains a stored cross-site scripting vulnerability that allows attackers to inject malicious scripts by submitting crafted input to the schedule endpoint. Attackers can submit POST requests with JavaScript payloads in the SCHNAME parameter to execute arbitrary code in administrators' browsers when the schedule page is accessed.

A vulnerability, which was classified as problematic, has been found in Comodo Dragon up to 134.0.6998.179. Affected by this issue is some unknown functionality of the component IP DNS Leakage Detector. The manipulation leads to cleartext transmission of sensitive information. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A vulnerability, which was classified as critical, has been found in Comodo Internet Security Premium 12.3.4.8162. This issue affects some unknown processing of the file cis_update_x64.xml of the component Manifest File Handler. The manipulation of the argument binary/params leads to os command injection. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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 Firewall Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Comodo Firewall. 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 cmdagent executable. By creating a symbolic link, an attacker can abuse the application to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-21794.

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 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.

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.
