In products of the MSE6 product-family by Festo a remote authenticated, low privileged attacker could use functions of undocumented test mode which could lead to a complete loss of confidentiality, integrity and availability.

In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of the device.

In multiple products by Festo a remote unauthenticated attacker could use functions of an undocumented protocol which could lead to a complete loss of confidentiality, integrity and availability.

Festo control block CPX-CEC-C1 and CPX-CMXX in multiple versions allow unauthenticated, remote access to critical webpage functions which may cause a denial of service.

In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-refresh-request" POST request doesn’t check for port syntax. This can result in unauthorized execution of system commands with root privileges due to improper access control command injection.

In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-acknerr-request" POST request doesn’t check for port syntax. This can result in unauthorized execution of system commands with root privileges due to improper access control command injection.

In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-web-viewer-request-off" POST request doesn’t check for port syntax. This can result in unauthorized execution of system commands with root privileges due to improper access control command injection.

In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-web-viewer-request-on" POST request doesn’t check for port syntax. This can result in unauthorized execution of system commands with root privileges due to improper access control command injection.

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1 Modular Controller with CoDeSys and SoftMotion do not require authentication for connections to certain TCP ports, which allows remote attackers to (1) modify the configuration via a request to the debug service on port 4000 or (2) delete log entries via a request to the log service on port 4001.

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1 Modular Controller with CoDeSys and SoftMotion provide an undocumented access method involving the FTP protocol, which could allow a remote attacker to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.
