What is CVE-2023-45886?

The BGP daemon (bgpd) in IP Infusion ZebOS versions up to 7.10.6 is susceptible to a denial of service attack. Remote attackers can exploit this vulnerability by sending specifically crafted BGP update messages that contain malformed attributes. This oversight in attribute handling may cause the BGP daemon to crash or become unresponsive, impacting network operations and service availability. Both service providers and organizations using IP Infusion ZebOS should take immediate action to safeguard their networks against possible exploitation.
