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.

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 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.

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.

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 Control PKI Exposure Enables Remote Certificate Access

A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all services remain available, only unencrypted communication is possible if the certificates are deleted.

CODESYS Toolkit Exposes Sensitive Files via Default Permissions

CODESYS Runtime Toolkit-based products may expose sensitive files to local low-privileged operating system users due to default file permissions.

CODESYS Control DoS via Unauthenticated NULL Pointer Dereference

An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition.

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 Control Audit Log Format String DoS

An unauthenticated remote attacker may be able to control the format string of messages processed by the Audit Log of the CODESYS Control runtime system, potentially resulting in a denial‑of‑service (DoS) condition.

CODESYS Control Boot Application Replacement Enables Code Execution

A low-privileged remote attacker may be able to replace the boot application of the CODESYS Control runtime system, enabling unauthorized code execution.

CODESYS Control - Invalid type usage in visualization

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.

CODESYS: Multiple products prone to improperly restricted memory operations

An authenticated, remote attacker may use a Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple versions of multiple CODESYS products to force a denial-of-service situation.

CODESYS: Multiple products prone to Improper Input Validation

An authenticated, remote attacker may use a improper input validation vulnerability in the CmpApp/CmpAppBP/CmpAppForce Components of multiple CODESYS products in multiple versions to read from an invalid address which can lead to a denial-of-service condition.

CODESYS: Multiple products prone to Improper Input Validation

In multiple CODESYS products in multiple versions an unauthorized, remote attacker may use a improper input validation vulnerability to read from invalid addresses leading to a denial of service.

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.
