AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
SQL injection in Real State Services 1.0 login allows unauthenticated remote attackers to execute arbitrary SQL commands.
Vulnerability
A SQL injection vulnerability exists in the /loginuser.php file of code-projects Real State Services version 1.0. The Username POST parameter is directly used in SQL queries without proper sanitization or validation, allowing an attacker to inject malicious SQL code. This vulnerability affects all installations of version 1.0 [2].
Exploitation
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted POST request to /loginuser.php with a malicious Username parameter. For example, a time-based blind SQL injection payload such as abc' AND (SELECT 4692 FROM (SELECT(SLEEP(5)))xenu) AND 'BVKZ'='BVKZ can be used. No authentication or prior access is required [2].
Impact
Successful exploitation allows an attacker to perform unauthorized SQL queries on the underlying database. This can lead to data leakage (e.g., sensitive user credentials), data tampering, and in some cases full database compromise. The impact is severe as it threatens the confidentiality, integrity, and availability of the system [2].
Mitigation
As of the publication date (2026-06-01), no official fix or patched version has been released by the vendor. Users should consider restricting network access to the application or implementing a web application firewall (WAF) to filter malicious SQL injection attempts. Monitoring database logs for suspicious queries is also recommended. The application may be end-of-life or unmaintained [2].

Vulnerability mechanics
Root cause
"Missing input validation and sanitization of the `username` parameter in `/loginuser.php` allows direct injection of user-controlled data into SQL queries."
Attack vector
An unauthenticated attacker sends a crafted POST request to `/loginuser.php` containing malicious SQL payloads in the `username` parameter. No login or authorization is required [ref_id=1]. The payload shown in the advisory uses time-based blind SQL injection with `SLEEP(5)` to extract database information. This allows the attacker to manipulate SQL queries and perform unauthorized operations on the backend database. [CWE-89]
Affected code
The vulnerability resides in the file `/loginuser.php` of the Real State Services 1.0 application. The `username` parameter passed via POST is used directly in SQL queries without sanitization or validation, leading to SQL injection. [ref_id=1]
What the fix does
The advisory recommends using prepared statements and parameter binding to separate SQL code from user input, treating user-supplied values as pure data rather than executable SQL. Additional mitigations include strict input validation and filtering, minimizing database user permissions, and conducting regular security audits. [ref_id=1] No patch diff is available in the bundle.
Preconditions
- authNo authentication or prior access required; the login endpoint is publicly accessible
- networkAttacker must be able to send HTTP POST requests to the target server
- inputThe username parameter is accepted without sanitization and interpolated into SQL queries
Reproduction
Send a POST request to `http://<target>/Real-Estate/loginuser.php` with the body `username=abc' AND (SELECT 4692 FROM (SELECT(SLEEP(5)))xenu) AND 'BVKZ'='BVKZ&password=123456&type=normal`. A 5-second delay confirms the time-based blind SQL injection. [ref_id=1]
