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…

An Improper Authentication issue was discovered in WAGO PFC200 Series 3S CoDeSys Runtime versions 2.3.X and 2.4.X. An attacker can execute different unauthenticated remote operations because of the CoDeSys Runtime application, which is available via network by default on Port…

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.

An issue was discovered on WAGO e!DISPLAY 762-3000 through 762-3003 devices with firmware before FW 02. The vulnerability allows an authenticated user to upload arbitrary files to the file system with the permissions of the web server.

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…

ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO - Programmable Logic Controllers, multiple versions. Researchers have found some controllers are susceptible to a denial-of-service attack due to a flood of network packets.

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…

An issue was discovered on WAGO e!DISPLAY 762-3000 through 762-3003 devices with firmware before FW 02. Weak permissions allow an authenticated user to overwrite critical files by abusing the unrestricted file upload in the WBM.

An issue was discovered on WAGO e!DISPLAY 762-3000 through 762-3003 devices with firmware before FW 02. The vulnerability can be exploited by authenticated and unauthenticated users by sending special crafted requests to the web server allowing injecting code within the WBM. The…

Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be…

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.

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.

An unauthenticated remote attacker can exploit a hidden function in the CLI prompt to escape the restricted interface, leading to full compromise of the device.

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

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…

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.
