Codesys Gateway vulnerabilities

CVE-2022-47391 [HIGH] CWE-20 CVE-2022-47391: In multiple CODESYS products in multiple versions an unauthorized, remote attacker may use a imprope In multiple CODESYS products in multiple versions an unauthorized, remote attacker may use a improper input validation vulnerability to read from invalid addresses leading to a denial of service.

CVE-2022-30792 [HIGH] CWE-400 CVE-2022-30792: In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

CVE-2022-30791 [HIGH] CWE-400 CVE-2022-30791: In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an u 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.

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-2022-22514 [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.
