CVE-2023-22817 | Server-side Request Forgery vulnerability in Western Digital My Cloud, My Cloud Home and SanDisk ibi products

Server-side request forgery (SSRF) vulnerability that could allow a rogue server on the local network to modify its URL using another DNS address to point back to the loopback adapter. This could then allow the URL to exploit other vulnerabilities on the local server. This was addressed by fixing DNS addresses that refer to loopback. This issue affects My Cloud OS 5 devices before 5.27.161, My Cloud Home, My Cloud Home Duo and SanDisk ibi devices before 9.5.1-104.

Base score Version Severity Vector Exploitability Impact Score source
5.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
