CVE-2019-3783

CVE-2019-3783 describes a critical vulnerability in Cloud Foundry Stratos versions prior to 2.3.0, where the application is deployed with a publicly exposed default session store secret. This flaw allows an authenticated attacker to brute-force and hijack other users' active Stratos sessions, enabling them to act on behalf of the compromised user with full access to their privileges. With a CVSS score of 8.8 (HIGH), the vulnerability poses a significant risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality, integrity, and availability impacts. Despite its severity, there is no evidence of active exploitation, publicly available exploit code in Metasploit or ExploitDB, or significant community discussion or media coverage surrounding this CVE.
