30
FAUCET Score

CVE-2020-15188 is an Unauthenticated Remote Code Execution (RCE) vulnerability affecting SOY CMS versions 3.0.2.327 and earlier. This critical flaw allows remote attackers to execute arbitrary code without authentication when the inquiry form feature is enabled, stemming from unrestricted unserialization of form data. With a CVSS score of 9.8, it presents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
