CVE-2019-5167 1 Wago 2 Pfc200 Firmware, Pfc 200 2024-11-21 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-2019-5081 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2024-11-21 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-2019-5080 1 Wago 4 Pfc 100, Pfc 100 Firmware, Pfc 200 and 1 more 2024-11-21 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.
