An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
In CODESYS Control in multiple versions a improper restriction of operations within the bounds of a memory buffer allow an remote attacker with user privileges to gain full access of the device.
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.
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.
In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of 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.
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.
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 Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of service (DoS).
CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.
An issue was discovered in CODESYS Development System before 3.5.16.0. CODESYS WebVisu and CODESYS Remote TargetVisu are susceptible to privilege escalation.
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.
3S-Smart Software Solutions GmbH CODESYS V3 OPC UA Server, all versions 3.5.11.0 to 3.5.15.0, allows an attacker to send crafted requests from a trusted OPC UA client that cause a NULL pointer dereference, which may trigger a denial-of-service condition.
An issue was discovered in 3S-Smart CODESYS before 3.5.15.0 . Crafted network packets cause the Control Runtime to crash.
An issue was discovered in 3S-Smart CODESYS V3 through 3.5.12.30. A user with low privileges can take full control over the runtime.
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.
