Description

This security bulletin contains information about 1 vulnerability.

1) Information disclosure (CVE-ID: CVE-2023-50263)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to improper access control in the db-file-storage file access views when handling requests to /files/get/ and /files/download/. A remote attacker can send a request with a known file name to disclose sensitive information.

No URL mechanism is provided for listing or traversing available file names, so exploitation requires knowledge or guessing of a valid file name or path.

Remediation

Install update from vendor's website.
