# Proof of Concept (PoC) - IDOR in DiagSystem
## Step by Step for Exploitation
1. **Access to the System:**
- Access the DiagSystem system through the link provided by the clinic.
- Use the credentials received to log in.
2. **Identification of the Vulnerable Point:**
- After logging in, access your own exam.
- Note the exam URL, which contains a `cod` and `codexame` parameter.
- Example of URL:
```
http://x.x.x.x:8081/diagsystem/PACS/atualatendimento_jpeg.php?cod=10677441&tp=JPEG&codexame=10677448
```
3. **Parameter Manipulation:**
- Change the value of the `cod` parameter to a different number. - Modify the value of the `codexame` parameter to a number close to the original.
- Access the new modified URL in the browser.
4. **Exploitation Verification:**
- If the page loads and displays exams from other patients, the IDOR vulnerability is confirmed.
- If access is denied or an error is returned, there may be a protection mechanism.
5. **Impact of the Vulnerability:**
- Any authenticated user can access third-party exams simply by modifying parameters in the URL.
- Serious privacy flaw and exposure of sensitive patient data.
6. **Mitigation Recommendations:**
- Implement authentication and authorization checks on endpoints.
- Avoid the use of predictable sequential identifiers.
- Adopt secure tokens to control access to exams.
- Perform security audits to identify other similar flaws. |
