CVE-2018-5955

87
FAUCET Score

CVE-2018-5955 describes a critical vulnerability in GitStack versions up to 2.3.10, where insufficient input filtering allows unauthenticated attackers to create new user accounts on the server by manipulating username and password fields via the rest/user/ URI. This flaw carries a CVSS score of 9.8 (Critical), indicating it can be exploited remotely with low complexity, leading to full compromise of confidentiality, integrity, and availability. While not on the KEV catalog, multiple public exploit modules exist, including Metasploit and ExploitDB entries for both user creation and remote code execution, yet community discussion and media coverage remain notably low.
