Certain devices in the WAGO System I/O Field series activate an internal diagnostic capability during the initial startup sequence. This functionality is not formally documented and becomes accessible without authentication for a brief period in the early boot phase. During this window, an unauthenticated remote attacker can gain access to the internal system processes, resulting in full system compromise.

In Wago Smart Designer in versions up to 2.33.1 a low privileged remote attacker may enumerate projects and usernames through iterative requests to an specific endpoint.

An authenticated remote attacker with high privileges can exploit the OpenVPN configuration via the web-based management interface of a WAGO PLC. If user-defined scripts are permitted, OpenVPN may allow the execution of arbitrary shell commands enabling the attacker to run arbitrary commands on the device.

WAGO 750-8212 PFC200 G2 2ETH RS firmware contains a privilege escalation vulnerability that allows attackers to manipulate user session cookies. Attackers can modify the cookie's 'name' and 'roles' parameters to elevate from ordinary user to administrative privileges without authentication.

An unauthenticated remote attacker can abuse unsafe sscanf calls within the checkcookie() function to write arbitrary data into fixed-size stack buffers which leads to full device compromise.

An unauthenticated remote attacker can abuse unsafe sscanf calls within the checkaccount() function to write arbitrary data into fixed-size stack buffers which leads to full device compromise.

During a short time frame while the device is booting an unauthenticated remote attacker can send traffic to unauthorized networks due to the switch operating in an undefined state until a CPU-induced reset allows proper configuration.

A remote unauthenticated attacker may use default certificates to generate JWT Tokens and gain full access to the tool and all connected devices.

An unauthenticated remote attacker can trick an admin to visit a website containing malicious java script code. The current overly permissive CORS policy allows the attacker to obtain any files from the file system.

A low privileged attacker can set the date of the devices to the 19th of January 2038 an therefore exceed the 32-Bit time limit. This causes the date of the switch to be set back to January 1st, 1970.

A low privileged user can set the date of the devices to the 19th of January 2038 an therefore exceed the 32-Bit time limit. This causes some functions to work unexpected or stop working at all. Both during runtime and after a restart.

An attacker with low privileges can manipulate the requested memory size, causing the application to use an invalid memory area. This could lead to a crash of the application but it does not affected other applications.

An unauthenticated remote attacker can cause a DoS in the controller due to uncontrolled resource consumption.

A low privileged remote attacker may modify the BACNet service properties due to incorrect permission assignment for critical resources which may lead to a DoS limited to BACNet communication.

A low privileged remote attacker can specify an arbitrary file on the filesystem which may lead to an arbitrary file writes with root privileges.

A low privileged remote attacker can overwrite an arbitrary file on the filesystem which may lead to an arbitrary file read with root privileges.

A low privileged remote attacker can overwrite an arbitrary file on the filesystem leading to a DoS and data loss.

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.

A low privileged remote attacker may modify the boot mode configuration setup of the device, leading to modification of the firmware upgrade process or a denial-of-service attack.

A low privileged remote attacker may modify the docker settings setup of the device, leading to a limited DoS.

An unautheticated remote attacker could send specifically crafted packets to a affected device. If an authenticated user then views that data in a specific page of the web-based management a buffer overflow will be triggered to gain full access of the device.

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.

A vulnerability in the web-based management allows an unauthenticated remote attacker to inject arbitrary system commands and gain full system control. Those commands are executed with root privileges. The vulnerability is located in the user request handling of the web-based management.

Wago web-based management of multiple products has a vulnerability which allows an local authenticated attacker to change the passwords of other non-admin users and thus to escalate non-root privileges.

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.

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.

Multiple WAGO devices in multiple versions may allow an authenticated remote attacker with high privileges to DoS the device by sending a specifically crafted packet to the CODESYS V2 runtime.

Multiple WAGO devices in multiple versions may allow an authenticated remote attacker with high privileges to DoS the device by sending a malformed packet.

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.

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.
