CVE-2022-45137 1 Wago 14 751-9301, 751-9301 Firmware, 752-8303\/8000-002 and 11 more 2023-03-08 N/A 6.1 MEDIUM
The configuration backend of the web-based management is vulnerable to reflected XSS (Cross-Site Scripting) attacks that targets the users browser. This leads to a limited impact of confidentiality and integrity but no impact of availability.
CVE-2022-45138 1 Wago 14 751-9301, 751-9301 Firmware, 752-8303\/8000-002 and 11 more 2023-03-07 N/A 9.8 CRITICAL
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.
CVE-2022-45139 1 Wago 14 751-9301, 751-9301 Firmware, 752-8303\/8000-002 and 11 more 2023-03-07 N/A 5.3 MEDIUM
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.
CVE-2022-45140 1 Wago 14 751-9301, 751-9301 Firmware, 752-8303\/8000-002 and 11 more 2023-03-07 N/A 9.8 CRITICAL
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.
CVE-2020-6090 1 Wago 2 Pfc200, Pfc200 Firmware 2023-02-07 9.0 HIGH 7.2 HIGH
An exploitable code execution vulnerability exists in the Web-Based Management (WBM) functionality of WAGO PFC 200 03.03.10(15). A specially crafted series of HTTP requests can cause code execution resulting in remote code execution. An attacker can make an authenticated HTTP request to trigger this vulnerability.
CVE-2022-3738 1 Wago 14 Cc100, Cc100 Firmware, Edge Controller and 11 more 2023-01-27 N/A 5.9 MEDIUM
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.
CVE-2019-5185 1 Wago 2 Pfc200, Pfc200 Firmware 2021-07-21 4.4 MEDIUM 7.0 HIGH
An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200. An attacker can send a specially crafted packet to trigger the parsing of this cache file. At 0x1ea28 the extracted state value from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=X1 state=<contents of state node> using sprintf(). The destination buffer sp+0x40 is overflowed with the call to sprintf() for any state values that are greater than 512-len("/etc/config-tools/config_interfaces interface=X1 state=") in length. Later, at 0x1ea08 strcpy() is used to copy the contents of the stack buffer that was overflowed sp+0x40 into sp+0x440. The buffer sp+0x440 is immediately adjacent to sp+0x40 on the stack. Therefore, there is no NULL termination on the buffer sp+0x40 since it overflowed into sp+0x440. The strcpy() will result in invalid memory access. An state value of length 0x3c9 will cause the service to crash.
CVE-2019-5135 1 Wago 4 Pfc100, Pfc100 Firmware, Pfc200 and 1 more 2021-07-21 5.0 MEDIUM 5.3 MEDIUM
An exploitable timing discrepancy vulnerability exists in the authentication functionality of the Web-Based Management (WBM) web application on WAGO PFC100/200 controllers.

This affects WAGO PFC200 Firmware version 03.00.39(12) and version 03.01.07(13), and WAGO PFC100 Firmware version 03.00.39(12).
CVE-2019-5186 1 Wago 2 Pfc200, Pfc200 Firmware 2021-07-21 4.4 MEDIUM 7.0 HIGH
An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200. An attacker can send a specially crafted packet to trigger the parsing of this cache file.At 0x1eb9c the extracted interface element name from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=<contents of interface element> using sprintf(). The destination buffer sp+0x40 is overflowed with the call to sprintf() for any interface values that are greater than 512-len("/etc/config-tools/config_interfaces interface=") in length. Later, at 0x1ea08 strcpy() is used to copy the contents of the stack buffer that was overflowed sp+0x40 into sp+0x440. The buffer sp+0x440 is immediately adjacent to sp+0x40 on the stack. Therefore, there is no NULL termination on the buffer sp+0x40 since it overflowed into sp+0x440. The strcpy() will result in invalid memory access. An interface value of length 0x3c4 will cause the service to crash.
CVE-2019-5160 1 Wago 2 Pfc200, Pfc200 Firmware 2021-07-21 6.5 MEDIUM 9.1 CRITICAL
An exploitable improper host validation vulnerability exists in the Cloud Connectivity functionality of WAGO PFC200 Firmware versions 03.02.02(14), 03.01.07(13), and 03.00.39(12). A specially crafted HTTPS POST request can cause the software to connect to an unauthorized host, resulting in unauthorized access to firmware update functionality. An attacker can send an authenticated HTTPS POST request to direct the Cloud Connectivity software to connect to an attacker controlled Azure IoT Hub node.
CVE-2019-5166 1 Wago 2 Pfc200, Pfc200 Firmware 2021-07-21 4.6 MEDIUM 7.8 HIGH
An exploitable stack buffer overflow vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 version 03.02.02(14).

CVE-2019-5167 1 Wago 2 Pfc200 Firmware, Pfc 200 2020-08-24 7.2 HIGH 7.8 HIGH
An exploitable command injection vulnerability exists in the iocheckd service ‘I/O-Check’ function of the WAGO PFC 200 version 03.02.02(14). At 0x1e3f0 the extracted dns value from the xml file is used as an argument to /etc/config-tools/edit_dns_server %s dns-server-nr=%d dns-server-name=<contents of dns node> using sprintf(). This command is later executed via a call to system(). This is done in a loop and there is no limit to how many dns entries will be parsed from the xml file.
CVE-2019-5134 1 Wago 4 Pfc100, Pfc100 Firmware, Pfc200 and 1 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
