WAGO: multiple products - Loss of MAC-Address-Filtering after reboot

WAGO Series PFC100/PFC200, Series Touch Panel 600, Compact Controller CC100 and Edge Controller in multiple versions are prone to a loss of MAC-Address-Filtering after reboot. This may allow an remote attacker to circumvent the reach the network that should be protected by the MAC address filter.

CODESYS V3 prone to Inadequate Password Hashing

In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of the device.

WAGO I/O-Check Service prone to Out-of-bounds Write

In WAGO I/O-Check Service in multiple products an attacker can send a specially crafted packet containing OS commands to crash the diagnostic tool and write memory.

WAGO I/O-Check Service prone to Memory Overflow

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to crash the iocheck process and write memory resulting in loss of integrity and DoS.

WAGO I/O-Check Service prone to Out-of-bounds Read

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service and an limited out-of-bounds read.

WAGO I/O-Check Service prone to Allocation of Resources Without Limits or Throttling

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service.

An issue was discovered in WAGO 750-8202/PFC200 prior to FW04 (released August 2015), WAGO 750-881 prior to FW09 (released August 2016), and WAGO 0758-0874-0000-0111. By accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to edit and to view settings without authenticating.

WAGO IO 750-849 01.01.27 and WAGO IO 750-881 01.02.05 do not contain privilege separation.

WAGO IO 750-849 01.01.27 and 01.02.05, WAGO IO 750-881, and WAGO IO 758-870 have weak credential management.

WAGO I/O System 758 model 758-870, 758-874, 758-875, and 758-876 Industrial PC (IPC) devices have default passwords for unspecified Web Based Management accounts, which makes it easier for remote attackers to obtain administrative access via a TCP session.

The Linux Console on the WAGO I/O System 758 model 758-870, 758-874, 758-875, and 758-876 Industrial PC (IPC) devices has a default password of wago for the (1) root and (2) admin accounts, (3) a default password of user for the user account, and (4) a default password of guest for the guest account, which makes it easier for remote attackers to obtain login access via a TELNET session, a different vulnerability than CVE-2012-3013.

WAGO: Missing authentication for config export functionality in multiple products

The vulnerability allows a remote unauthenticated attacker to download a backup file, if one exists. That backup file might contain sensitive information like credentials and cryptographic material. A valid user has to create a backup after the last reboot for this attack to be successfull.

WAGO: Exposure of configuration interface in unmanaged switches

In WAGO Unmanaged Switch (852-111/000-001) in firmware version 01 an undocumented configuration interface without authorization allows an remote attacker to read system information and configure a limited set of parameters.

WAGO: Missing Authentication for Critical Function

The configuration backend allows an unauthenticated user to write arbitrary data with root privileges to the storage, which could lead to unauthenticated remote code execution and full system compromise.

WAGO: Origin validation error through CORS misconfiguration

A CORS Misconfiguration in the web-based management allows a malicious third party webserver to misuse all basic information pages on the webserver. In combination with CVE-2022-45138 this could lead to disclosure of device information like CPU diagnostics. As there is just a limited amount of information readable the impact only affects a small subset of confidentiality.

WAGO: Missing Authentication for Critical Function

The configuration backend of the web-based management can be used by unauthenticated users, although only authenticated users should be able to use the API. The vulnerability allows an unauthenticated attacker to read and set several device parameters that can lead to full compromise of the device.

WAGO: Multiple products vulnerable to local file inclusion

On affected Wago products an remote attacker with administrative privileges can access files to which he has already access to through an undocumented local file inclusion. This access is logged in a different log file than expected.

WAGO: WBM Command Injection in multiple products

In multiple products of WAGO a vulnerability allows an unauthenticated, remote attacker to create new users and change the device configuration which can result in unintended behaviour, Denial of Service and full system compromise.

WAGO: Series 750-3x/-8x prone to MODBUS server DoS

Uncontrolled resource consumption in Series WAGO 750-3x/-8x products may allow an unauthenticated remote attacker to DoS the MODBUS server with specially crafted packets.

WAGO Improper Input Validation in IEC61850 Server / Telecontrol

The MMS Interpreter of WagoAppRTU in versions below 1.4.6.0 which is used by the WAGO Telecontrol Configurator is vulnerable to malformed packets. An remote unauthenticated attacker could send specifically crafted packets that lead to a denial-of-service condition until restart of the affected device.
