Vulnerability from variot - Updated: 2023-12-18 12:18

An industry-wide vulnerability has been identified in the implementation of the Open Shortest Path First (OSPF) routing protocol used on some Lenovo switches. Exploitation of these implementation flaws may result in attackers being able to erase or alter the routing tables of one or many routers, switches, or other devices that support OSPF within a routing domain. Part of Lenovo and IBM Switch Open Shortest Path First (OSPF) Routing protocol implementations have input validation vulnerabilities and data integrity validation vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. LenovoFlexSystemFabricCN409310GbConvergedScalableSwitch, etc. are all switch devices of China Lenovo. IBM1GL2-7SLBswitchforBladecenter and so on are all IBM IBM switch devices. A number of security vulnerabilities exist in OpenShortestPathFirst (OSPF) routingprotocol implementations in Lenovo and IBM NetworkingSwitches. An attacker could use this vulnerability to delete and change routing tables. Lenovo and IBM Networking Switches are prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks

    "data": "An industry-wide vulnerability has been identified in the implementation of the Open Shortest Path First (OSPF) routing protocol used on some Lenovo switches. Exploitation of these implementation flaws may result in attackers being able to erase or alter the routing tables of one or many routers, switches, or other devices that support OSPF within a routing domain. Part of Lenovo and IBM Switch Open Shortest Path First (OSPF) Routing protocol implementations have input validation vulnerabilities and data integrity validation vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. LenovoFlexSystemFabricCN409310GbConvergedScalableSwitch, etc. are all switch devices of China Lenovo. IBM1GL2-7SLBswitchforBladecenter and so on are all IBM IBM switch devices. A number of security vulnerabilities exist in OpenShortestPathFirst (OSPF) routingprotocol implementations in Lenovo and IBM NetworkingSwitches. An attacker could use this vulnerability to delete and change routing tables. Lenovo and IBM Networking Switches are prone to a security-bypass vulnerability. \nAn attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks",
