CVE-2020-9502 is a critical session ID predictability vulnerability affecting certain Dahua products manufactured before December 2019. An unauthenticated attacker can remotely exploit this flaw with low complexity by predicting session IDs to construct malicious data packets, leading to complete compromise of confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high CVSS score of 9.8 underscores the severe risk.
