Uncontrolled Memory Allocation in CODESYS Gateway Client

The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a denial-of-service condition thus leading to a total loss of availablity.

Improper Synchronization in Monitoring in CODESYS Control Runtime

Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition.

Out-of-bounds Write in CODESYS PROFINET Controller

An out‑of‑bounds write vulnerability in the CODESYS PROFINET Controller allows an unauthenticated attacker on the same network segment to send malformed PROFINET communication data that triggers an exception in the affected PLC application. The exception is handled by the CODESYS Control runtime system and results in a controlled stop of the PLC application.

UCanCode E-XD++ Visualization Enterprise Suite Untrusted Pointer Dereference RCE

UCanCode E-XD++ Visualization Enterprise Suite contains an untrusted pointer dereference vulnerability via the TKDRAWCAD.TKDrawCADCtrl.1 ActiveX control. This is because it exposes a RotateShape method that dereferences a user-supplied pointer without sufficient validation. A crafted input may cause the control to dereference an attacker-controlled pointer, enabling remote code execution in the context of the hosting process. The vulnerability requires user interaction (instantiation of the ActiveX control via a web page or a file).

CODESYS: Multiple products prone to stack based out-of-bounds write

An authenticated, remote attacker may use a stack based out-of-bounds write vulnerability in the CmpTraceMgr Component of 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.

CODESYS: Multiple products prone to stack based out-of-bounds write

An authenticated, remote attacker may use a stack based out-of-bounds write vulnerability in the CmpTraceMgr Component of 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.

CODESYS Visualization - Insufficiently Protected Credentials

The affected product may expose credentials remotely between low privileged visualization users during concurrent login operations due to insufficient isolation of authentication data. The vulnerability affects only login operations within an active visualization session.

CODESYS Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of service (DoS).

CODESYS: Exposure of Resource to Wrong Sphere in CODESYS V3

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.

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

Incorrect Default Permissions in CODESYS Development System

The affected product creates a directory with insecure default permissions during administrative installation. This allows a low-privileged local attacker to modify a temporary file defining the components to be installed, enabling local privilege escalation by forcing the deployment of arbitrary components.

Incorrect Default Permissions in CODESYS Development System

The affected product extracts installation files to a temporary directory with incorrect default permissions during administrative installation. A low-privileged local attacker can exploit a TOCTOU race condition with a practical time window to replace verified files with malicious ones before installation, resulting in local privilege escalation.

Out-of-bounds Write in CODESYS Control

The affected products perform improper length checking when parsing incoming HTTP requests, resulting in a size-limited out-of-bounds write. An unauthenticated remote attacker can exploit this flaw to cause a denial of service via a system crash on the affected device.

Incorrect Authorization in CODESYS Control

The affected products insufficiently verify authorization when deleting user accounts. An authenticated, low-privileged remote user can exploit this vulnerability to delete other users, including those with higher privileges.

Improper resource management in CODESYS Modbus TCP Server

An unauthenticated remote attacker may exhaust all available TCP connections in the CODESYS Modbus TCP Server stack if a race condition in connection handling is successfully exploited, preventing legitimate clients from establishing new connections.

Improper timeout handling in CODESYS EtherNetIP

An unauthenticated remote attacker is able to exhaust all available TCP connections in the CODESYS EtherNet/IP adapter stack, preventing legitimate clients from establishing new connections.

CODESYS Installer TOCTOU Privilege Escalation

If a legitimate user confirms a self-update prompt or initiate an installation of a CODESYS Development System, a low privileged local attacker can gain elevated rights due to a TOCTOU vulnerability in the CODESYS installer.

CODESYS Control - Linux/QNX SysSocket flaw

An unauthenticated remote attacker, who beats a race condition, can exploit a flaw in the communication servers of the CODESYS Control runtime system on Linux and QNX to trigger an out-of-bounds read via crafted socket communication, potentially causing a denial of service.

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.

Amazon AWS Client VPN has a buffer overflow that could potentially allow a local actor to execute arbitrary commands with elevated permissions. This is resolved in 3.11.1 on Windows, 3.9.1 on macOS, and 3.12.1 on Linux. NOTE: although the macOS resolution is the same as for CVE-2024-30165, this vulnerability on macOS is not the same as CVE-2024-30165.
