PC Protect Antivirus v4.14.31 installs by default to %PROGRAMFILES(X86)%\PCProtect with very weak folder permissions, granting any user full permission "Everyone: (F)" to the contents of the directory and its subfolders. In addition, the program installs a service called SecurityService that runs as LocalSystem. This allows any user to escalate privileges to "NT AUTHORITY\SYSTEM" by substituting the service's binary with a Trojan horse. PC Protect Antivirus versión v4.14.31, se instala por defecto en %PROGRAMFILES(X86)%\PCProtect con permisos de carpeta muy débiles, otorgando a cualquier usuario permiso completo "Everyone: (F)" para el contenido del directorio y sus subcarpetas. Además, el programa instala un servicio llamado SecurityService que es ejecutado como LocalSystem. • https://flipflopsecurity.wordpress.com/2019/10/07/pc-protect-v4-14-31-privilege-esclation • CWE-276: Incorrect Default Permissions •

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. Se puede desencadenar un fallo use-after-free en el contenedor sandbox implementado en cmdguard.sys en Comodo Antivirus 12.0.0.6870 debido a una condición de carrera al manejar solicitudes IRP_MJ_CLEANUP en el minifiltro para notificaciones de cambio de directorio. Esto permite que un atacante provoque una denegación de servicio (BSOD) cuando se ejecuta un ejecutable dentro del contenedor. • http://rce4fun.blogspot.com/2019/08/comodo-antivirus-sandbox-race-condition.html https://github.com/SouhailHammou/Exploits/blob/master/CVE-2019-14694%20-%20Comodo%20AV%20Sandbox%20Race%20Condition%20UAF/comodo_av_uaf_poc.c • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

In Avast Antivirus before 19.4, a local administrator can trick the product into renaming arbitrary files by replacing the Logs\Update.log file with a symlink. The next time the product attempts to write to the log file, the target of the symlink is renamed. This defect can be exploited to rename a critical product file (e.g., AvastSvc.exe), causing the product to fail to start on the next system restart. En Avast Antivirus antes de 19.4, un administrador local puede engañar al producto para que cambie el nombre de los archivos arbitrarios al reemplazar el archivo Logs \ Update.log con un enlace simbólico. La próxima vez que el producto intente escribir en el archivo de registro, se cambiará el nombre del destino del enlace simbólico. • http://www.mcerlane.co.uk/CVE-2019-11230 http://www.securityfocus.com/bid/109344 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

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. • https://www.tenable.com/security/research/tra-2019-34 • CWE-787: Out-of-bounds Write •
