An authenticated, remote attacker may use a out-of-bounds write vulnerability in multiple CODESYS products in multiple versions to write data into memory which can lead to a denial-of-service condition, memory overwriting, or remote code execution.

Multiple CODESYS products in multiple versions are prone to a improper input validation vulnerability. An authenticated remote attacker may craft specific requests that use the vulnerability leading to a denial-of-service condition.

Improper Input Validation vulnerability in multiple CODESYS V3 products allows an authenticated remote attacker to block consecutive logins of a specific type.

In multiple products of CODESYS v3 in multiple versions a remote low privileged user could utilize this vulnerability to read and modify system files and OS resources or DoS the device.

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.

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.

A remote, unauthenticated attacker can send a specific crafted HTTP or HTTPS requests causing a buffer over-read resulting in a crash of the webserver of the CODESYS Control runtime system.

A bug in CmpUserMgr component can lead to only partially applied security policies. This can result in enabled, anonymous access to components part of the applied security policy.

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.
