| Information Disclosure is possible on WAGO Series PFC100 and PFC200 devices before FW12 due to improper access control. A remote attacker can check for the existence of paths and file names via crafted HTTP requests. | |||||
| 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-2022-45139 | 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-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-2019-5186 | 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. | |||||
