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

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

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.

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.
