CVE-2019-5081 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 10.0 HIGH 9.8 CRITICAL
An exploitable heap buffer overflow vulnerability exists in the iocheckd service ''I/O-Chec'' functionality of WAGO PFC 200 Firmware version 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a heap buffer overflow, potentially resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5078 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 9.4 HIGH 9.1 CRITICAL
An exploitable denial of service vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a denial of service, resulting in the device entering an error state where it ceases all network communications. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5079 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
An exploitable heap buffer overflow vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a heap buffer overflow, potentially resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5077 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 8.5 HIGH 9.1 CRITICAL
An exploitable denial-of-service vulnerability exists in the iocheckd service ‘’I/O-Chec’’ functionality of WAGO PFC 200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC 100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a denial of service, resulting in the device entering an error state where it ceases all network communications. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5074 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 10.0 HIGH 9.8 CRITICAL
An exploitable stack buffer overflow vulnerability exists in the iocheckd service ''I/O-Check'' functionality of WAGO PFC200 Firmware version 03.01.07(13), WAGO PFC200 Firmware version 03.00.39(12) and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a stack buffer overflow, resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5080 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 6.4 MEDIUM 9.1 CRITICAL
An exploitable denial-of-service vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A single packet can cause a denial of service and weaken credentials resulting in the default documented credentials being applied to the device. An attacker can send an unauthenticated packet to trigger this vulnerability.
CVE-2019-5167 1 Wago 2 Pfc200 Firmware, Pfc 200 2023-12-10 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-2019-5073 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 5.0 MEDIUM 5.3 MEDIUM
An exploitable information exposure vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause an external tool to fail, resulting in uninitialized stack data to be copied to the response packet buffer. An attacker can send unauthenticated packets to trigger this vulnerability.
CVE-2019-5075 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2023-12-10 10.0 HIGH 9.8 CRITICAL
An exploitable stack buffer overflow vulnerability exists in the command line utility getcouplerdetails of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets sent to the iocheckd service "I/O-Check" can cause a stack buffer overflow in the sub-process getcouplerdetails, resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability.
