CVE-2020-23355 describes a critical authentication bypass vulnerability in Codiad 2.8.4, specifically within the Authenticate() function of class.user.php. This flaw allows attackers to bypass authentication using "magic hashes," where certain encrypted or hashed password formats (e.g., starting with "0e") are incorrectly validated, enabling unauthorized access. With a CVSS score of 7.5 (High), this vulnerability is easily exploitable over the network without requiring any user interaction or privileges, potentially leading to a complete compromise of integrity. Despite its severity, there is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), and it has not been observed in active exploitation or garnered significant community discussion or media coverage.
