Together, these vulnerabilities could allow a remote, unauthenticated attacker to gain administrative privileges if an SSO solution is not configured for authentication.\r\n\r\n### Description\r\nSaviynt Enterprise Identity Cloud contains two vulnerabilities in the password reset feature for the local authentication system. Specifying the `id` parameter returns user names and it is common that accounts with administrative privileges have low (often single digit) `id` values.\r\n\r\n`/ECM/maintenance/forgotpasswordstep1?otpConfig=false&id=5`\r\n\r\nIt is then possible to either unhide a button or directly access a URL that bypasses verification and allows the password to be changed. Accessing a login URL with the new credentials yields cookies that can be used to authenticate to the Enerprise Identity Cloud instance.\r\n\r\nIf another authentication or SSO system is configured, then it is not possible to exploit these vulnerabilities.\r\n\r\n### Impact\r\nA remote, unauthenticated attacker can enumerate users and bypass authentication to change the password of an existing administrative user. The attacker can then perform administrative actions and possibly make changes to other connected authentication systems.\r\n\r\n### Solution\r\nSaviynt has deployed a backend update for the software that resolves the issue in Saviynt IGA Release v5.5 SP2.x and later versions. As an additional layer of security, as the impacted URLs are not commonly used by customers leveraging SSO, Saviynt has blocked access to the URLs needed to exploit these vulnerabilities.\r\n\r\nSaviynt users should not need to take any action but might want to confirm they are running a fixed version.\r\n\r\n### Acknowledgements\r\nThis document was written by Eric Hatleback and Art Manion.","title":"Summary"},{"category":"legal_disclaimer","text":"THIS DOCUMENT IS PROVIDED ON AN 'AS IS' BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
