CODESYS V2 Web-Server before 1.1.9.20 has a Stack-based Buffer Overflow.

CODESYS V2 Web-Server before 1.1.9.20 has an Improperly Implemented Security Check.

CODESYS V2 Web-Server before 1.1.9.20 has Improper Access Control.

CODESYS V2 Web-Server before 1.1.9.20 has an Out-of-bounds Write.

Crafted web server requests can be utilised to read partial stack or heap memory or may trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.

CODESYS V2 Web-Server before 1.1.9.20 has an Out-of-bounds Read.

On WAGO PFC200 devices in different firmware versions with special crafted packets an authorised attacker with network access to the device can access the file system with higher privileges.

A crafted request with invalid offsets may cause an out-of-bounds read or write access in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition or local memory overwrite.

CODESYS V2 runtime system SP before 2.4.7.55 has a Heap-based Buffer Overflow.

CODESYS V2 runtime system before 2.4.7.55 has Improper Input Validation.

Uncontrolled resource consumption in Series WAGO 750-3x/-8x products may allow an unauthenticated remote attacker to DoS the MODBUS server with specially crafted packets.

In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests may cause a Null pointer dereference in the CODESYS web server and may result in a denial-of-service condition.

CODESYS V2 Web-Server before 1.1.9.20 has a a Buffer Copy without Checking the Size of the Input.

Crafted web server requests may cause a heap-based buffer overflow and could therefore trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.

In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests can trigger a parser error. Since the parser result is not checked under all conditions, a pointer dereference with an invalid address can occur. This leads to a denial of service situation.

A crafted request may cause a read access to an uninitialized pointer in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition.

On WAGO PFC200 devices in different firmware versions with special crafted packets an attacker with network access to the device could cause a denial of service for the login service of the runtime.

CODESYS V2 runtime system SP before 2.4.7.55 has Improper Neutralization of Special Elements used in an OS Command.
