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

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.

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.

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 unauthenticated attacker can trick a local user into executing arbitrary code by opening a deliberately manipulated CODESYS project file with a CODESYS development system. This arbitrary code is executed in the user context.

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.

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

An unauthenticated remote attacker can bypass the user management in CODESYS Visualization and read visualization template files or static elements by means of forced browsing.

An unauthenticated remote attacker can gain access to sensitive information including authentication information when using CODESYS OPC UA Server with the non-default Basic128Rsa15 security policy.

Insufficient path validation in CODESYS Control allows low privileged attackers with physical access to gain full filesystem access.

A low privileged remote attacker may modify the configuration of the CODESYS V3 service through a missing authentication vulnerability which could lead to full system access and/or DoS.

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

An unauthenticated remote attacker can use a malicious OPC UA client to send a crafted request to affected CODESYS products which can cause a DoS due to incorrect calculation of buffer size.

In Weintek's cMT3000 HMI Web CGI device, the cgi-bin codesys.cgi contains a stack-based buffer overflow, which could allow an anonymous attacker to hijack control flow and bypass login authentication.

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 missing Brute-Force protection in CODESYS Development System prior to 3.5.19.20 allows a local attacker to have unlimited attempts of guessing the password within an import dialog.

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

This vulnerability is different to CVE-2023-37559

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.

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.
