Practical Analysis and Simulation of OSPF Protocol Vulnerabilities : A practical exploration of documented vulnerabilities associated with OSPFv2

Sammanfattning

Todays rapid advancements and developments within the field of IT bring both challenges and vulnerabilities. The growing digital presence results in heightened risks associated with sabotage and unauthorized access. Addressing these threats necessitates a continuous assessment of the potential vulnerabilities within the IT landscape. Open Shortest Path First (OSPF) is a router protocol utilized to determine the optimal routes for transmitting data packets from a source to their destination across a computer network. Given OSPF’s broad application, the potential for attacks becomes more conceivable. Router adjacencies and links form a fundamental part of the protocol, and in this study, we explore the potential to introduce malicious information along with examining its persistence. We simulate two different attacks in Core Network Emulator called remote false adjacency and disguised LSA. Through these two attacks, we successfully introduced both false adjacencies and malicious links across several different network topologies.
