Summary

An improper implementation of the Open Shortest Path First (OSPF) routing protocol in various Huawei networking products allows attackers to manipulate the Link Status Age. By sending specially crafted LSA packets to the affected devices, an attacker can set the LS age to MaxAge (3600 seconds), which can lead to a poisoned route table and enable Denial of Service (DoS) attacks. This vulnerability highlights the critical need for secure implementations in networking protocols.
