CODESYS Embedded TargetVisu Toolkit

CODESYS V3 web server before 3.5.15.40, as used in CODESYS Control runtime systems, has a buffer overflow.

CODESYS V3 web server, all versions prior to 3.5.14.10, allows an attacker to send specially crafted http or https requests which could cause a stack overflow and create a denial-of-service condition or allow remote code execution.

CODESYS 3 web server before 3.5.15.20, as distributed with CODESYS Control runtime systems, has a Buffer Overflow.

CODESYS Control Runtime system before 3.5.17.10 has a Heap-based Buffer Overflow.

Codesys Runtime Improper Limitation of a Pathname

A component of the CODESYS Control runtime system allows read and write access to configuration files

CODESYS V3 web server, all versions prior to 3.5.14.10, allows an attacker to send specially crafted http or https requests which may allow access to files outside the restricted working directory of the controller.

CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.

Special HTTP(s) Requests can cause a buffer-read causing a crash of the webserver and the runtime system.

Communication Components in multiple CODESYS products vulnerable to communication channel disruption

CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Attackers can send crafted communication packets to change the router's addressing scheme and may re-route, add, remove or change low level communication packages.

In CODESYS V3 web server before 3.5.17.10, files or directories are accessible to External Parties.

CODESYS V3: CmpBlkDrvTcp allows unauthenticated attackers to block all its available TCP connections

CODESYS: CmpChannelServer, CmpChannelServerEmbedded allow unauthenticated attackers to block all their available communication channels
