CVSS: 7.5EPSS: 0%CPEs: 20EXPL: 0CVE-2022-30791 – CODESYS V3: CmpBlkDrvTcp allows unauthenticated attackers to block all its available TCP connections
https://notcve.org/view.php?id=CVE-2022-30791
In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected. En CmpBlkDrvTcp de CODESYS versión V3 en múltiples versiones un consumo no controlado de recursos permite a un atacante no autorizado bloquear nuevas conexiones TCP. Las conexiones existentes no están afectadas • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=17128&token=bee4d8a57f19be289d623ec90135493b5f9179e3&download= • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-22517
An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. This results in the communication channel to be closed. Un atacante remoto no autenticado puede interrumpir los canales de comunicación presentes entre los productos CODESYS al adivinar un ID de canal válido e inyectando paquetes.

CVSS: 7.1EPSS: 0%CPEs: 21EXPL: 0CVE-2022-22514 – Untrusted Pointer Dereference in multiple CODESYS products can lead to a DoS.
https://notcve.org/view.php?id=CVE-2022-22514
An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash. Un atacante remoto autentificado puede obtener acceso a un puntero desreferenciado contenido en una solicitud. Los accesos pueden llevar posteriormente a la sobreescritura local de la memoria en el CmpTraceMgr, por lo que el atacante no puede obtener los valores leídos internamente ni controlar los valores a escribir. • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=17093&token=15cd8424832ea10dcd4873a409a09a539ee381ca&download= • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-822: Untrusted Pointer Dereference •
