Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Easy!Appointments has a broken access control flaw in `/services/{serviceId}`. <br>π₯ **Consequences**: Low-privilege users can steal, alter, or delete ANY service data, including admin accounts.β¦
π‘οΈ **Root Cause**: **CWE-639** (Authorization Bypass Through User Control). <br>π **Flaw**: The API endpoint fails to verify if the requester actually owns the resource. No proper permission check before action!
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Easy!Appointments** (Web-based scheduling system). <br>β οΈ **Note**: Specific version numbers not listed in data, but the `/services/{serviceId}` interface is the target. Check your deployment!
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: <br>ποΈ **Read**: View any user's services. <br>βοΈ **Modify**: Change service details. <br>ποΈ **Delete**: Destroy service records. <br>π **Impact**: Even Admin services are vulnerable!
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. <br>π **Auth**: Requires **Low Privilege** (PR:L). <br>π **Network**: Remote (AV:N). <br>π±οΈ **UI**: No user interaction needed (UI:N). Easy to exploit!
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: **No PoC provided** in current data. <br>π΅οΈ **Status**: References point to GitHub repo. Wild exploitation likely possible due to simple logic flaw, but no specific exploit code shared yet.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: <br>1. Scan for Easy!Appointments instances. <br>2. Test `/services/{serviceId}` with low-priv tokens. <br>3. Try modifying/deleting a service ID you don't own. If it works -> **VULNERABLE**!
π§ **Workaround**: <br>π« **Block Access**: Restrict `/services/{serviceId}` endpoint via WAF/Network ACLs. <br>π **Verify**: Manually audit backend code for authorization checks on service endpoints.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. <br>π **CVSS**: High Impact (I:H, A:H). <br>β‘ **Action**: Patch immediately or isolate the service. Data loss risk is real and easy to trigger!
