Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OneUptime < 10.0.21 has a critical **Authorization & Tenant Isolation Bypass**. π **Consequences**: Leads to **Cross-Tenant Data Leakage** and full **Account Takeover**.β¦
π‘οΈ **Root Cause**: **CWE-285** (Improper Authorization). The system fails to properly verify if a user has permission to access resources belonging to a different tenant. π« **Flaw**: Logic error in access control checks.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **OneUptime** (Open Source Monitoring Solution). π¦ **Version**: All versions **prior to 10.0.21**. If you are running 10.0.20 or lower, you are vulnerable! β οΈ
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Hackers can **bypass tenant isolation**. They can read **other tenants' data** (cross-tenant leak) and potentially **take over accounts**. π΅οΈββοΈ High impact on confidentiality and integrity.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Low**. CVSS Vector: `AV:N/AC:L/PR:L/UI:N`. π **Auth Required**: Yes (PR:L - Low Privileges). You need a valid account, but no complex setup or UI interaction needed. Easy to exploit if you have access.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exploit**: **No**. The `pocs` array is empty. No public Proof-of-Concept (PoC) or wild exploitation scripts are currently available. π€«
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Check your **OneUptime version**. If it is **< 10.0.21**, you are at risk. π Look for the specific **Tenant Isolation** feature in your admin panel. Ensure no cross-tenant data access is possible.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: **Yes**. Official patch released in **v10.0.21**. π₯ **Mitigation**: Upgrade immediately to version 10.0.21 or later. Check the [GitHub Release](https://github.com/OneUptime/oneuptime/releases/tag/10.0.21).
Q9What if no patch? (Workaround)
π **No Patch?**: If you cannot upgrade, **isolate** the instance. Restrict network access. Monitor logs for unusual **cross-tenant API calls**. π‘οΈ Limit user privileges to minimize damage.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. CVSS Score is likely **Critical** (H:H/H:H/H:H). π **Priority**: Patch immediately. Data leakage and account takeover are severe risks. Do not delay! πββοΈπ¨
