Technical details
A local file inclusion (LFI) vulnerability exists in the `/api/v1/report/summary/{type}` API endpoint of SmarterTools SmarterMail. The root cause is improper path validation (CWE-22) in the `{type}` parameter, which allows an authenticated attacker to traverse the file system and read arbitrary .json files. When combined with the application's use of weak encryption algorithms and hardcoded cryptographic keys, an attacker can decrypt sensitive configuration files to retrieve stored passwords and 2FA secrets for all users. The vulnerability is addressed in SmarterMail build 9560 and later.
