CVE-2025-2126: Jux Real Estate SQL Injection Vulnerability

CVE-2025-2126 Overview

CVE-2025-2126 is a SQL injection vulnerability in JoomlaUX JUX Real Estate 3.4.0, a property listing extension for the Joomla content management system. The flaw resides in the GET parameter handler at /extensions/realestate/index.php/properties/list/list-with-sidebar/realties. Attackers can manipulate the title parameter to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable and the exploit details have been disclosed publicly. The vendor was contacted prior to disclosure but did not respond. The flaw is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements).

Critical Impact

Remote attackers with low privileges can inject SQL commands through the title GET parameter to access, modify, or extract data from the Joomla backend database.

Affected Products

• JoomlaUX JUX Real Estate 3.4.0
• Joomla installations running the JUX Real Estate extension
• Web applications exposing the /extensions/realestate/index.php/properties/list/list-with-sidebar/realties endpoint

Technical Details for CVE-2025-2126

Vulnerability Analysis

The vulnerability stems from improper neutralization of user-controlled input in the JUX Real Estate component's property listing handler. The title GET parameter is concatenated directly into a SQL query without parameterized binding or input sanitization. Attackers can craft malicious values for title to break out of the intended query context and append arbitrary SQL clauses.

The affected endpoint is reachable over the network and requires only low privilege access. Because the extension processes the parameter server-side during property searches, attackers can probe the database structure, exfiltrate stored records, and potentially modify content depending on the underlying database account permissions.

With an EPSS percentile near 80%, the vulnerability has a higher-than-average probability of exploitation activity compared to the broader CVE population. Public exploit material has been published via VulDB, lowering the technical barrier for opportunistic attackers.

Root Cause

The root cause is the absence of parameterized queries or input validation when processing the title GET parameter inside the realty listing controller. User-supplied data flows directly into SQL execution paths, satisfying the conditions described in CWE-89.

Attack Vector

An attacker issues a crafted HTTP GET request to the vulnerable endpoint with a malicious title value. No user interaction is required, and the attack succeeds over the network. The injected SQL executes within the Joomla database context, allowing data disclosure, tampering, or denial of service against the database service.

For technical exploitation details, refer to the VulDB entry #299039 and the VulDB submission #509884.

Detection Methods for CVE-2025-2126

Indicators of Compromise

• HTTP GET requests to /extensions/realestate/index.php/properties/list/list-with-sidebar/realties containing SQL syntax in the title parameter, such as UNION SELECT, SLEEP(, OR 1=1, or comment sequences (--, #).
• Web server logs showing repeated requests to the realty listing endpoint with unusual encoded characters or quote symbols in title.
• Database error messages or anomalous response sizes returned from the realty listing URL.

Detection Strategies

• Deploy web application firewall (WAF) rules to inspect GET parameters for SQL injection signatures targeting the JUX Real Estate endpoint.
• Enable Joomla query logging and review database audit logs for unexpected SELECT, UNION, or INFORMATION_SCHEMA queries originating from the realty listing controller.
• Correlate web access logs with database logs to identify SQL statements that match suspicious inbound HTTP requests.

Monitoring Recommendations

• Monitor outbound traffic from the Joomla server for unexpected large data transfers indicative of database exfiltration.
• Alert on HTTP 500 responses or database timeouts from the realty listing endpoint, which can indicate blind or time-based injection attempts.
• Track repeated requests to the vulnerable URL from a single source IP and rate-limit or block automated scanners.

How to Mitigate CVE-2025-2126

Immediate Actions Required

• Restrict public access to the /extensions/realestate/index.php/properties/list/list-with-sidebar/realties endpoint until a vendor patch is available.
• Apply WAF signatures that block SQL metacharacters and known injection patterns in the title GET parameter.
• Audit the Joomla database account used by JUX Real Estate and remove unnecessary privileges such as FILE, CREATE, or DROP.

Patch Information

No vendor patch is available at the time of publication. According to VulDB, JoomlaUX was contacted prior to disclosure but did not respond. Administrators should monitor the JoomlaUX product page and Joomla extension directory for any future security release that addresses CVE-2025-2126.

Workarounds

• Temporarily disable the JUX Real Estate 3.4.0 extension within the Joomla administrator panel if the property listing functionality is non-essential.
• Place the affected endpoint behind authentication or IP allowlisting using web server configuration directives.
• Implement reverse proxy filtering to reject requests where the title parameter contains SQL keywords or non-printable characters.

# Example Apache rule to block SQL injection patterns in the title parameter
<LocationMatch "/extensions/realestate/index\.php/properties/list/list-with-sidebar/realties">
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (?i)(union[\s+]+select|select.+from|sleep\(|or[\s+]+1=1|--|/\*) [NC]
    RewriteRule .* - [F,L]
</LocationMatch>
