Retest Report Template

Document remediation verification results after clients fix reported vulnerabilities. Confirms fixes are effective and no regressions occurred.

When to Use

After clients report they've remediated findings, perform targeted retesting to verify fixes are effective. This template documents those verification results.

## DETAILED RETEST RESULTS

### VLN-001: SQL Injection in Login

| Attribute | Value |
|-----------|-------|
| **Original Severity** | Critical |
| **Retest Status** | ✅ Remediated |
| **Tested On** | [Date] |

#### Original Issue
SQL injection vulnerability in the username parameter of the login form.

#### Remediation Implemented
Client implemented parameterized queries and added input validation.

#### Verification Testing
**Test Performed:**
```
POST /login
username: admin'--
password: test
```

**Result:**
- Application now returns "Invalid credentials" error
- No SQL error messages exposed
- Unable to bypass authentication

#### Evidence
[Screenshot showing failed injection attempt]

#### Conclusion
✅ **Remediated** - The SQL injection vulnerability has been successfully fixed.

### VLN-002: Missing CSRF Protection

| Attribute | Value |
|-----------|-------|
| **Original Severity** | High |
| **Retest Status** | ⚠️ Partially Remediated |
| **Tested On** | [Date] |

#### Original Issue
No CSRF tokens on state-changing operations.

#### Remediation Implemented
Client added CSRF tokens to password change and email update forms.

#### Verification Testing
**Tested Endpoints:**
- [x] /account/change-password - CSRF token present and validated
- [x] /account/update-email - CSRF token present and validated
- [ ] /account/delete - CSRF token missing
- [ ] /api/transfer - CSRF token missing

#### Evidence
[Screenshot showing CSRF token in protected forms]
[Screenshot showing missing protection on other forms]

#### Conclusion
⚠️ **Partially Remediated** - CSRF protection added to some forms but not all 
state-changing operations. Recommend extending protection to all endpoints.

### VLN-003: Weak Password Policy

| Attribute | Value |
|-----------|-------|
| **Original Severity** | Medium |
| **Retest Status** | ❌ Not Remediated |
| **Tested On** | [Date] |

#### Original Issue
Password policy allowed weak passwords (minimum 6 characters, no complexity).

#### Client Response
Client stated fix was deployed on [Date].

#### Verification Testing
**Test Performed:**
Attempted to set password to: "123456"

**Result:**
Password was accepted without error.

#### Evidence
[Screenshot showing weak password accepted]

#### Conclusion
❌ **Not Remediated** - Weak passwords are still accepted. Fix does not appear 
to be deployed or is not functioning correctly.

## NEW ISSUES IDENTIFIED

During retesting, the following new issues were identified:

### NEW-001: Verbose Error Messages

| Attribute | Value |
|-----------|-------|
| **Severity** | Low |
| **Affected Asset** | /api/login |

#### Description
While testing the SQL injection fix, verbose database error messages were 
observed when malformed input is provided.

#### Evidence
```
Error: PDOException: SQLSTATE[42000]: Syntax error in query...
```

#### Recommendation
Implement generic error messages for production environment.

---

## RECOMMENDATIONS

### Immediate Actions Required
1. Complete remediation of VLN-002 (CSRF) on remaining endpoints
2. Verify deployment of VLN-003 (Password Policy) fix
3. Address NEW-001 (Error Messages)

### Process Improvements
- Implement pre-deployment security testing
- Create security regression test suite
- Establish fix verification process before marking issues resolved

**END OF REPORT**
      

Status Definitions

✅ Remediated

Vulnerability is fully fixed. Original attack vector no longer works. No bypass techniques successful.

⚠️ Partially Remediated

Fix is incomplete. Some attack vectors blocked but others remain. Or fix can be bypassed with modifications.

❌ Not Remediated

No effective fix implemented. Original vulnerability still exploitable as documented in initial report.

🆕 New Issue

New vulnerability discovered during retesting. May be introduced by the fix or previously missed.
