CODESYS: Improper Input Validation in CmpApp component

In multiple Codesys products in multiple versions, after successful authentication as a user, specific crafted network communication requests with inconsistent content can cause the CmpApp component to read internally from an invalid address, potentially leading to a denial-of-service condition. This vulnerability is different to CVE-2023-37545, CVE-2023-37546, CVE-2023-37548, CVE-2023-37549 and CVE-2023-37550

Insecure transmission of credentials

In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.

CODESYS: CmpChannelServer, CmpChannelServerEmbedded allow unauthenticated attackers to block all their available communication channels

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.

CODESYS V3: CmpBlkDrvTcp allows unauthenticated attackers to block all its available TCP connections

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.

Special HTTP(s) Requests can cause a buffer-read causing a crash of the webserver and the runtime system.

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.

Communication Components in multiple CODESYS products vulnerable to communication channel disruption

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.

CODESYS driver SysDrv3S allows SYSTEM users on Microsoft Windows to read and write in restricted memory space.

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

A component of the CODESYS Control runtime system allows read and write access to configuration files

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.

Untrusted Pointer Dereference in multiple CODESYS products can lead to a DoS.

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.

Null Pointer Dereference in multiple CODESYS products can lead to a DoS.

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

Improper Certificate Validation in CODESYS Git

Affected versions of CODESYS Git in Versions prior to V1.1.0.0 lack certificate validation in HTTPS handshakes. CODESYS Git does not implement certificate validation by default, so it does not verify that the server provides a valid and trusted HTTPS certificate. Since the certificate of the server to which the connection is made is not properly verified, the server connection is vulnerable to a man-in-the-middle attack.

The Package Manager of CODESYS Development System 3 before 3.5.17.0 does not check the validity of packages before installation and may be used to install CODESYS packages with malicious content.

CODESYS Development System 3 before 3.5.17.0 displays or executes malicious documents or files embedded in libraries without first checking their validity.

A unsafe deserialization vulnerability exists in the ObjectManager.plugin ProfileInformation.ProfileData functionality of CODESYS GmbH CODESYS Development System 3.5.16 and 3.5.17. A specially crafted file can lead to arbitrary command execution. An attacker can provide a malicious file to trigger this vulnerability.

A unsafe deserialization vulnerability exists in the PackageManagement.plugin ExtensionMethods.Clone() functionality of CODESYS GmbH CODESYS Development System 3.5.16. A specially crafted file can lead to arbitrary command execution. An attacker can provide a malicious file to trigger this vulnerability.

A unsafe deserialization vulnerability exists in the ComponentModel ComponentManager.StartupCultureSettings functionality of CODESYS GmbH CODESYS Development System 3.5.16 and 3.5.17. A specially crafted file can lead to arbitrary command execution. An attacker can provide a malicious file to trigger this vulnerability.

A unsafe deserialization vulnerability exists in the ComponentModel Profile.FromFile() functionality of CODESYS GmbH CODESYS Development System 3.5.16 and 3.5.17. A specially crafted file can lead to arbitrary command execution. An attacker can provide a malicious file to trigger this vulnerability.

An issue was discovered in CODESYS Development System before 3.5.16.0. CODESYS WebVisu and CODESYS Remote TargetVisu are susceptible to privilege escalation.
