sfewer-r7 at February 22, 2024 4:54pm UTC reported:
Based on writing the Metasploit exploit module for this vulnerability, I have rated the exploitability as very high, as leveraging CVE-2203-1709 to create a new administrator account is trivial. To leverage the vulnerability to get RCE requires more steps, but it is not that complex and exploitation appears reliable. The attacker value for this vulnerability is also very high given the nature of the target software.
