Critical 9.8
Path traversal in dynamically created BACnet File Objects
The object name of a dynamically created BACnet File Object is interpreted as a file path without sufficient validation. Because relative paths are not limited to the intended directory, an unauthenticated remote attacker can traverse outside of it and read o…

Critical 9.8
Unauthenticated Access to Internal Diagnostic Interface
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 boo…

Critical 10.0
Hidden CLI Function Allows Root Access
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.
-
Critical 9.8
Hardcoded Key Allows Credential Disclosure
User credentials are stored using AES‑ECB encryption with a hardcoded key. An unauthenticated remote attacker obtaining the configuration file can decrypt and recover plaintext usernames and passwords, especially when combined with the authentication bypass.

Critical 9.8
Stack Overflow via Oversized Cookie Fields in lighttpd
Improper length handling when parsing multiple cookie fields (including TRACKID) allows an unauthenticated remote attacker to send oversized cookie values and trigger a stack buffer overflow, resulting in a denial‑of‑service condition and possible remote code…
-
Critical 9.8
Stack Overflow via SESSIONID Cookie in lighttpd
An unauthenticated remote attacker can send a crafted HTTP request containing an overly long SESSIONID cookie. This can trigger a stack buffer overflow in the modified lighttpd server, causing it to crash and potentially enabling remote code execution due to …

Critical 9.8
Stack-based buffer overflow via unsafe sscanf in check_cookie()
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.
-
Critical 9.8
Stack-based buffer overflow via unsafe sscanf in check_account()
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.
-
Critical 9.8
Missing Authentication for Database Access in Web Application
The database for the web application is exposed without authentication, allowing an unauthenticated remote attacker to gain unauthorized access and potentially compromise it.
-
Critical 10.0
WAGO: Vulnerability in WAGO Device Sphere
A remote unauthenticated attacker may use default certificates to generate JWT Tokens and gain full access to the tool and all connected devices.
-
Critical 9.8
WAGO: OS Command Injection Vulnerability in Managed Switch
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…
-
Critical 9.8
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.
-
Critical 9.8
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.
-
Critical 9.8
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 ca…
-
Critical 9.1
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.
-
Critical 9.8
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.
-
Critical 9.1
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.
-
Critical 9.8
WAGO: Authentication Vulnerability in Web-Based Management
This vulnerability allows an attacker who has access to the WBM to read and write settings-parameters of the device by sending specifically constructed requests without authentication on multiple WAGO PLCs in firmware versions up to FW07.
-
Critical 9.1
WAGO: PFC200 Access to files outside the home directory
On WAGO PFC200 devices in different firmware versions with special crafted packets an authorised attacker with network access to the device can access the file system with higher privileges.
-
Critical 10.0
WAGO: Managed Switches: Unauthorized creation of user accounts
In multiple managed switches by WAGO in different versions without authorization and with specially crafted packets it is possible to create users.
