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

CODESYS: web server vulnerable to DoS

An unauthenticated remote attacker can causes the CODESYS web server to access invalid memory which results in a DoS.

Codesys Runtime Improper Limitation of a Pathname

The CODESYS runtime system in multiple versions allows an remote low privileged attacker to use a path traversal vulnerability to access and modify all system files as well as DoS the device.

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

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.

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

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.

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

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.

Communication Components in multiple CODESYS products vulnerable to communication channel disruption

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.

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

A remote, authenticated attacker could utilize the control program of the CODESYS Control runtime system to use the vulnerability in order to read and modify the configuration file(s) of the affected products.

Untrusted Pointer Dereference in multiple CODESYS products can lead to a DoS.

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.

Null Pointer Dereference in multiple CODESYS products can lead to a DoS.

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

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

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.

CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.

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

CODESYS 3 web server before 3.5.15.20, as distributed with 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 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.
