In plain terms It can be attacked from anywhere on the internet without logging in, and nobody has to click anything. If it works, the attacker can read data, change data and take it offline. ### The official description CubeFS is an open-source cloud-native file storage system. A vulnerability was found in CubeFS prior to version 3.3.1 that could allow users to read sensitive data from the logs which could allow them escalate privileges. CubeFS leaks configuration keys in plaintext format in the logs. These keys could allow anyone to carry out operations on blobs that they otherwise do not have permissions for. For example, an attacker that has succesfully retrieved a secret key from the logs can delete blogs from the blob store. The attacker can either be an internal user with limited privileges to read the log, or they can be an external user who has escalated privileges sufficiently to access the logs. The vulnerability has been patched in v3.3.1. There is no other mitigation than upgrading. ### What kind of flaw is it? - CWE-200: Exposure of Sensitive Information to an Unauthorized Actor ### How an attack on it works - Where an attacker can be: Anywhere on the internet - How hard it is to pull off: Easy: no special conditions - Login needed first: No login needed - Does someone have to click: No, nobody has to do anything - What an attacker gets: Can read data, change data and take it offline Severity vector: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H` ## Is CVE-2023-46741 being exploited?
