CVE-2022-31802 [CRITICAL] CWE-187 CVE-2022-31802: In CODESYS Gateway Server V2 for versions prior to V2.3.9.38 only a part of the the specified passwo In CODESYS Gateway Server V2 for versions prior to V2.3.9.38 only a part of the the specified password is been compared to the real CODESYS Gateway password. An attacker may perform authentication by specifying a small password that matches the corresponding part of the longer real CODESYS Gateway password.

CVE-2022-31804 [HIGH] CWE-789 CVE-2022-31804: The CODESYS Gateway Server V2 does not verifiy that the size of a request is within expected limits. The CODESYS Gateway Server V2 does not verifiy that the size of a request is within expected limits. An unauthenticated attacker may allocate an arbitrary amount of memory, which may lead to a crash of the Gateway due to an out-of-memory condition.

CVE-2022-31805 [HIGH] CWE-523 CVE-2022-31805: In the CODESYS Development System multiple components in multiple versions transmit the passwords fo In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.

CVE-2022-31803 [MEDIUM] CWE-400 CVE-2022-31803: In CODESYS Gateway Server V2 an insufficient check for the activity of TCP client connections allows In CODESYS Gateway Server V2 an insufficient check for the activity of TCP client connections allows an unauthenticated attacker to consume all available TCP connections and prevent legitimate users or clients from establishing a new connection to the CODESYS Gateway Server V2. Existing connections are not affected and therefore remain intact.

CVE-2022-22514 [HIGH] CWE-822 CVE-2022-22514: An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. 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.

CVE-2022-22517 [HIGH] CWE-334 CVE-2022-22517: An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS prod 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.

CVE-2022-22513 [MEDIUM] CWE-476 CVE-2022-22513: An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component o An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

CVE-2021-36764 [HIGH] CWE-476 CVE-2021-36764: In CODESYS Gateway V3 before 3.5.17.10, there is a NULL Pointer Dereference. Crafted communication r In CODESYS Gateway V3 before 3.5.17.10, there is a NULL Pointer Dereference. Crafted communication requests may cause a Null pointer dereference in the affected CODESYS products and may result in a denial-of-service condition.

CVE-2021-29241 [HIGH] CWE-476 CVE-2021-29241: CODESYS Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of ser CODESYS Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of service (DoS).

CVE-2021-29242 [HIGH] CWE-20 CVE-2021-29242: CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Attackers can send cra CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Attackers can send crafted communication packets to change the router's addressing scheme and may re-route, add, remove or change low level communication packages.

CVE-2020-7052 [MEDIUM] CWE-770 CVE-2020-7052: CODESYS Control V3, Gateway V3, and HMI V3 before 3.5.15.30 allow uncontrolled memory allocation whi CODESYS Control V3, Gateway V3, and HMI V3 before 3.5.15.30 allow uncontrolled memory allocation which can result in a remote denial of service condition.

CVE-2019-9009 [HIGH] CWE-755 CVE-2019-9009: An issue was discovered in 3S-Smart CODESYS before 3.5.15.0 . Crafted network packets cause the Cont An issue was discovered in 3S-Smart CODESYS before 3.5.15.0 . Crafted network packets cause the Control Runtime to crash.

CVE-2019-9010 [CRITICAL] CVE-2019-9010: An issue was discovered in 3S-Smart CODESYS V3 products. The CODESYS Gateway does not correctly veri An issue was discovered in 3S-Smart CODESYS V3 products. The CODESYS Gateway does not correctly verify the ownership of a communication channel.
