Product Overview
Product Name: Gotac Statistics Database System / Gotac Police Statistics Database
Product Type: Web-based law enforcement statistics and reporting platform
Deployment Model: On-premise (internal government or police networks)
Primary Usage: Crime statistics storage, reporting, analytics, and data exports
User Roles: Administrators, analysts, police officers, reporting staff
These systems are commonly deployed in trusted internal environments, which significantly increases the real-world risk when authentication or file-handling controls fail.
Executive Risk Summary
Three critical vulnerabilities affect the Gotac Statistics Database product family.
All vulnerabilities are unauthenticated, meaning an attacker does not need credentials to exploit them.
One of the vulnerabilities allows remote code execution, which can lead to full system compromise.
If exploited, an attacker could:
- Access police data without logging in
- Modify or delete official records
- Upload malicious files
- Execute operating-system commands
- Establish persistent backdoors
- Pivot to other internal systems
Attack complexity: Low
User interaction required: None
Overall severity: Critical

| CVE ID | Vulnerability | CVSS Score | Severity | Exploitability | Exploit Availability |
|---|---|---|---|---|---|

| CVE-2026-1021 | Arbitrary File Upload → RCE | 10.0 | Critical | Very High | Educational PoC feasible |

CVE-2026-1023 – Missing Authentication
Affected Component: Gotac Statistics Database System (core APIs)
Technical Description
Certain backend endpoints responsible for sensitive operations do not enforce authentication checks. Requests are processed even when no valid session, token, or credential is provided.
This flaw exists due to:
- Missing server-side authentication validation
- Improper authorization logic
- Over-reliance on frontend or client-side checks
As a result, the application trusts unauthenticated requests as legitimate.
How Exploitation Works
An attacker sends direct HTTP requests to internal API endpoints that were assumed to be protected.
Typical Attack Flow
- Attacker discovers the application endpoint (internal IP, VPN access, exposed interface)
- Sends a request directly to sensitive URLs
- Server processes the request without validating identity
- Data is returned or modified without authorization
Impact
- Unauthorized access to sensitive police statistics
- Data manipulation or deletion
- Corruption of reporting accuracy
- Legal, regulatory, and reputational consequences
MITRE ATT&CK Mapping
- T1190 – Exploit Public-Facing Application
- T1078 – Valid Accounts (bypass via missing validation)
Detection & Monitoring
Indicators of Compromise
- Successful access to admin or data endpoints without authentication
- API responses sent to anonymous requests
- Data modifications without recorded user context
Recommended Log Sources
- Web server access logs
- Application request logs
- API gateway or reverse proxy logs
- SIEM correlation logs
SIEM Detection Rules (Conceptual)
Rule 1 – Unauthenticated Sensitive API Access
IF http.request.uri CONTAINS "/api" OR "/admin"
AND authentication_token IS NULL
THEN ALERT "Unauthenticated access to sensitive endpoint"
Rule 2 – Unauthorized Data Modification
IF http.method IN (POST, PUT, DELETE)
AND session_id IS MISSING
THEN ALERT "Possible unauthenticated data modification"
CVE-2026-1021 – Arbitrary File Upload Leading to Remote Code Execution
Affected Component: Gotac Police Statistics Database (file upload module)
Technical Description
The application allows file uploads without proper validation. Uploaded files are stored in a directory that allows execution by the web server.
Missing controls include:
- File extension validation
- MIME type enforcement
- Content inspection
- Execution restrictions on upload directories
This allows attackers to upload and execute malicious scripts.
How Exploitation Works
Exploitation Chain
- Attacker accesses upload endpoint (no authentication required)
- Uploads a malicious executable file
- File is saved in a web-accessible directory
- Attacker accesses the file via browser
- Server executes attacker-controlled code
Proof of Concept (Educational Use Only)
A basic educational PoC involves uploading a server-side script that:
- Accepts commands via URL parameters
- Executes those commands on the server
⚠️ This information is strictly for defensive testing and educational purposes.
Payload Concept (Non-operational Example)
- Script receives
cmdparameter - Passes parameter to system command execution
- Returns output in HTTP response
Impact
- Full compromise of application server
- Unauthorized database access
- Credential harvesting
- Persistent malware installation
- Lateral movement inside internal networks
MITRE ATT&CK Mapping
- T1190 – Exploit Public-Facing Application
- T1505.003 – Web Shell
- T1059 – Command and Scripting Interpreter
Detection & Monitoring
Indicators of Compromise
- Uploads of executable file types
- New files appearing in upload directories
- Web requests accessing uploaded scripts
- Unexpected outbound network connections
Recommended Log Sources
- File upload logs
- Web server access logs
- Endpoint Detection & Response (EDR) logs
- Firewall egress logs
SIEM Detection Rules (Conceptual)
Rule 1 – Suspicious File Upload
IF upload.filename EXTENSION IN ("jsp","php","aspx","war","exe")
THEN ALERT "Suspicious executable file upload"
Rule 2 – Execution from Upload Directory
IF http.request.uri MATCHES "/uploads/.*\.(jsp|php|aspx)"
THEN ALERT "Possible web shell execution"
Rule 3 – Server Command Execution
IF parent_process IS web_server
AND child_process IS command_shell
THEN ALERT "Web server spawning command shell"
CVE-2026-1019 – Missing Authentication
Affected Component: Gotac Police Statistics Database (reporting & export modules)
Technical Description
Certain reporting and data export endpoints fail to verify authentication. These endpoints allow unauthenticated users to retrieve or manipulate sensitive datasets.
This flaw is separate from CVE-2026-1023 but rooted in the same access-control weaknesses.
How Exploitation Works
- Attacker enumerates report or export URLs
- Sends direct requests without credentials
- Server returns full datasets or allows modifications
Impact
- Exposure of confidential police records
- Unauthorized data exports
- Manipulation of investigative data
- Loss of operational trust
MITRE ATT&CK Mapping
- T1213 – Data from Information Repositories
- T1078 – Valid Accounts (bypass)
Detection & Monitoring
Indicators
- Anonymous data exports
- Large data downloads without user context
- Access outside business hours
SIEM Detection Rule (Conceptual)
IF http.request.uri CONTAINS "/export"
AND authentication_token IS NULL
THEN ALERT "Unauthenticated data export detected"
Overall Risk Assessment
| Category | Risk Level |
|---|---|
| Confidentiality | Very High |
| Integrity | Very High |
| Availability | High |
| Attack Complexity | Low |
| Likelihood of Exploitation | High |
| Overall Risk | Critical |
Mitigation & Remediation
Immediate Defensive Actions
- Restrict network access to trusted IPs only
- Enforce VPN or internal segmentation
- Monitor logs for exploitation indicators
- Disable file uploads if not operationally required
Permanent Remediation (Official Fix)
Apply the official vendor security patch or upgrade addressing these vulnerabilities.
Official Patch / Upgrade Link

Hardening Recommendations
- Enforce authentication on all endpoints
- Implement strict role-based access control
- Validate file uploads and block executable content
- Disable script execution in upload directories
- Enable detailed application and database logging
- Integrate logs into a SIEM
- Perform periodic penetration testing
Final Takeaway
These vulnerabilities are highly exploitable, especially in trusted internal networks where such systems are often deployed. Immediate patching and active monitoring are strongly recommended.
