VAR-201810-1044
Vulnerability from variot - Updated: 2025-06-14 23:05WAGO 750-88X and WAGO 750-89X Ethernet Controller devices, versions 01.09.18(13) and before, have XSS in the SNMP configuration via the webserv/cplcfg/snmp.ssi SNMP_DESC or SNMP_LOC_SNMP_CONT field. WAGO 750-881 Ethernet Controller The device contains a cross-site scripting vulnerability.Information may be obtained and information may be altered. WAGO750-881EthernetControllerdevices is an Ethernet controller device from WAGO, Germany. The remote attacker can use the SNMP_DESC or SNMP_LOC_SNMP_CONT field to inject any web script or HTML. The vulnerability stems from the lack of correct validation of client data in WEB applications. An attacker could exploit this vulnerability to execute client code

WAGO 750-881 Ethernet Controller The device contains a cross-site scripting vulnerability.Information may be obtained and information may be altered. WAGO750-881EthernetControllerdevices is an Ethernet controller device from WAGO, Germany. The remote attacker can use the SNMP_DESC or SNMP_LOC_SNMP_CONT field to inject any web script or HTML. The vulnerability stems from the lack of correct validation of client data in WEB applications. An attacker could exploit this vulnerability to execute client code",

VAR-201804-1569
Vulnerability from variot - Updated: 2024-11-23 23:12Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be sent to Port 2455/TCP/IP, used in Codesys management software, which may result in a denial-of-service condition of communications with commissioning and service tools. Wago 750 series PLC Vulnerabilities exist in the firmware of improper shutdown and release of resources.Service operation interruption (DoS) There is a possibility of being put into a state. 750-880, 750-881, 750-852, etc. are all WAGO750 series Ethernet switches. The WAGO750 series has a denial of service vulnerability that can be exploited to cause a denial of service state to communicate with debug and service tools. Multiple WAGO Products are prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause denial-of-service condition. WAGO 750 Series PLCs, etc. are editable logic controller products of Germany WAGO Company. There is a security vulnerability in WAGO 750 Series PLCs using firmware version 10 and earlier. The vulnerability is caused by the program not implementing the three-way handshake correctly

"data": "Wago 750 Series PLCs with firmware version 10 and prior include a remote attack may take advantage of an improper implementation of the 3 way handshake during a TCP connection affecting the communications with commission and service tools. Specially crafted packets may also be sent to Port 2455/TCP/IP, used in Codesys management software, which may result in a denial-of-service condition of communications with commissioning and service tools. Wago 750 series PLC Vulnerabilities exist in the firmware of improper shutdown and release of resources.Service operation interruption (DoS) There is a possibility of being put into a state. 750-880, 750-881, 750-852, etc. are all WAGO750 series Ethernet switches. The WAGO750 series has a denial of service vulnerability that can be exploited to cause a denial of service state to communicate with debug and service tools. Multiple WAGO Products are prone to a denial-of-service vulnerability. \nAn attacker can exploit this issue to cause denial-of-service condition. WAGO 750 Series PLCs, etc. are editable logic controller products of Germany WAGO Company. There is a security vulnerability in WAGO 750 Series PLCs using firmware version 10 and earlier. The vulnerability is caused by the program not implementing the three-way handshake correctly",

VAR-201905-1110
Vulnerability from variot - Updated: 2024-11-23 23:08The Web-GUI on WAGO Series 750-88x (750-330, 750-352, 750-829, 750-831, 750-852, 750-880, 750-881, 750-882, 750-884, 750-885, 750-889) and Series 750-87x (750-830, 750-849, 750-871, 750-872, 750-873) devices has undocumented service access. Wago series 750-88x and 750-87x The device contains a vulnerability related to the use of hard-coded credentials.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state.
WAGO Series 750-88x and 750-87x have a vulnerability in trust management issues. The vulnerability stems from the lack of effective trust management mechanisms in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates and other attacks. Components. Successfully exploiting this issue allows a remote attacker to change the settings or alter the programming of the device. The following versions of Series 750-88x and 750-87x are affected: 750-330 firmware versions prior to FW14 750-352 firmware versions prior to FW14 750-829 firmware versions prior to FW14 750-831 firmware versions prior to FW14 750-852 firmware versions prior to FW14 750-880 firmware versions prior to FW14 750-881 firmware versions prior to FW14 750-882 firmware versions prior to FW14 750-884 firmware versions prior to FW14 750-885 firmware versions prior to FW14 750-889 firmware versions prior to FW14 750-830 firmware versions prior to FW06 750-849 firmware versions prior to FW08 750-871 firmware versions prior to FW11 750-872 firmware versions prior to FW07 750-873 firmware versions prior to FW07
