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.

An issue was discovered in 3S-Smart CODESYS V3 products. The application may utilize non-TLS based encryption, which results in user credentials being insufficiently protected during transport. All variants of the following CODESYS V3 products in all versions containing the CmpUserMgr component are affected regardless of the CPU type or operating system: CODESYS Control for BeagleBone, CODESYS Control for emPC-A/iMX6, CODESYS Control for IOT2000, CODESYS Control for Linux, CODESYS Control for PFC100, CODESYS Control for PFC200, CODESYS Control for Raspberry Pi, CODESYS Control RTE V3, CODESYS Control RTE V3 (for Beckhoff CX), CODESYS Control Win V3 (also part of the CODESYS Development System setup), CODESYS V3 Simulation Runtime (part of the CODESYS Development System), CODESYS Control V3 Runtime System Toolkit, CODESYS HMI V3.

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.

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.

The SysDrv3S driver in the CODESYS Control runtime system on Microsoft Windows allows any system user to read and write within restricted memory space.

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.

Use of Insufficiently Random Values exists in CODESYS V3 products versions prior V3.5.14.0.

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.

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.

Improper Communication Address Filtering exists in CODESYS V3 products versions prior V3.5.14.0.

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 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.

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.

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 multiple versions of multiple Codesys products, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpAppBP component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37552, CVE-2023-37553, CVE-2023-37555 and CVE-2023-37556.

In multiple Codesys products in multiple versions, after successful authentication as a user, specially crafted network communication requests can utilize the CmpApp component to download files with any file extensions to the controller. In contrast to the regular file download via CmpFileTransfer, no filtering of certain file types is performed here. As a result, the integrity of the CODESYS control runtime system may be compromised by the files loaded onto the controller.

After successful authentication as a user in multiple Codesys products in multiple versions, specific crafted network communication requests with inconsistent content can cause the CmpAppForce component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37558

In multiple versions of multiple Codesys products, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpAppBP component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37552, CVE-2023-37553, CVE-2023-37554 and CVE-2023-37555.

After successful authentication as a user in multiple Codesys products in multiple versions, specific crafted remote communication requests can cause the CmpAppBP component to overwrite a heap-based buffer, which can lead to a denial-of-service condition.
