Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Gardyn Cloud API has an **Access Control Error**. Unauthenticated users can access sensitive endpoints. ๐ **Consequences**: All registered user account info is exposed publicly.โฆ
๐ก๏ธ **Root Cause**: **CWE-306** (Missing Authentication for Critical Function). The flaw lies in the **Cloud API** endpoints lacking proper identity verification checks. ๐ซ No login required to view data.
Q3Who is affected? (Versions/Components)
๐ **Affected**: **Gardyn** indoor smart hydroponic systems. ๐ Specifically the **Cloud API** component. ๐ Vendor: Gardyn (USA). All connected devices relying on this API are at risk.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Actions**: Read **ALL** registered user account information. ๐ No privileges needed. ๐ต๏ธโโ๏ธ Can harvest PII, usernames, and account details without hacking individual accounts. High impact on Confidentiality.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **LOW**. โ๏ธ **Auth**: None required. ๐ **Network**: Remote (AV:N). ๐ฑ๏ธ **UI**: None needed. Anyone on the internet can trigger this. Extremely easy to exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp?**: **No PoC provided** in data. ๐ต๏ธโโ๏ธ However, given **CVSS 3.1/AV:N/AC:L/PR:N**, exploitation is trivial for any script kiddie. Wild exploitation likely imminent despite lack of specific PoC code.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Gardyn API endpoints. ๐งช Test for **401/403** responses on sensitive paths. If you get **200 OK** with user data without tokens, you are vulnerable. ๐ก Check vendor security page for status.
