The Library WagoAppRTU which is part of the Wago Telecontrol Configurator is prone to improper input validation. By sending specifically crafted MMS packets an attacker can trigger a denial-of-service condition.
Affected products are vulnerable to remote code execution via command injection in the web-based management by an attacker.
There is a misconfiguration of access rights to a configuration tool of the web-based-management for a specific user, which allows to reset passwords of other users (except root). This allows an authenticated attacker to elevate his privileges.
An attacker with administrative privileges which can access sensitive files can additionally access them in an unintended, undocumented way.
UPDATE 07.05.2025: The fixed versions have been updated, because the previously mentioned versions are still vulnerable to this issue. More details have been added to the hardware devices. More affected version numbers were added to the firmwares.
UPDATE A 26.09.2023:
Changed affected Version of e!Cockpit from < 1.11.2.0 to <= 1.11.2.0
Vulnerabilities are reported in WIBU-SYSTEMS Codemeter. WIBU-SYSTEMS Codemeter is installed by default during e!COCKPIT and WAGO-I/O-Pro (CODESYS 2.3) installations. All currently existing e!COCKPIT installation bundles and WAGO-I/O-Pro (CODESYS 2.3) installation bundles are affected with vulnerable versions of WIBU-SYSTEMS Codemeter.
UPDATE B 20.11.2023:
Removed CVE-2023-4701 because it was revoked.
Multiple WAGO devices are prone to vulnerabilites in the used CODESYS V3 framework.
A vulnerability allows Bluetooth LE pairing traffic to be sniffed and used to bypass authentication for pairing.
An authenticated attacker can send a malformed packet to trigger a device crash via the CODESYS V2 runtime commands parsing.
Update: 08.07.2024 release date of the updates has been changed.
