CVE-1999-0598

CVE-1999-0598 describes a critical vulnerability in network intrusion detection systems (IDS) where out-of-order packet handling can be exploited by attackers to evade detection. This allows malicious traffic to bypass security controls, effectively rendering the IDS useless. With a CVSS score of 10.0 (HIGH), this vulnerability is easily exploitable over the network with low attack complexity and no authentication, leading to complete compromise of confidentiality, integrity, and availability. The FAUCET Risk Score of 81/100 further emphasizes its severe nature. Despite its high severity, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage are also absent, indicating a lack of public attention for this older vulnerability.
