A vulnerability was found in PHPGurukul Land Record System 1.0 and classified as critical. Affected by this issue is some unknown functionality of the file /admin/property-details.php. The manipulation of the argument editid leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
Critical vulnerability exists in PHPGurukul Land Record System 1.0, allowing for remote SQL injection via the editid parameter in /admin/property-details.php. Successful exploitation grants an attacker the ability to read, modify, or delete sensitive data within the application's database, potentially leading to complete system compromise.
Step 1: Identify Vulnerable Parameter: The attacker identifies the editid parameter in the /admin/property-details.php file as a potential entry point for SQL injection.
Step 2: Craft Malicious Payload: The attacker constructs a malicious SQL injection payload designed to achieve a specific goal, such as retrieving sensitive data (e.g., database credentials, user information), modifying data, or executing arbitrary commands.
Step 3: Inject Payload: The attacker injects the crafted payload into the editid parameter through a GET or POST request to /admin/property-details.php.
Step 4: Execute Malicious Query: The vulnerable application executes the attacker's injected SQL code as part of its database query.
Step 5: Data Exfiltration/Manipulation: Based on the injected payload, the attacker either retrieves sensitive data, modifies existing data, or gains further control over the system.
The vulnerability stems from insufficient input validation and sanitization of the editid parameter within the /admin/property-details.php file. The application directly incorporates user-supplied data from editid into an SQL query without proper escaping or filtering. This allows an attacker to inject malicious SQL code, manipulating the query's logic and extracting or modifying data. The root cause is a lack of parameterized queries or prepared statements, which would prevent SQL injection by treating user input as data rather than executable code. The absence of input validation allows for crafted payloads to bypass security checks and execute arbitrary SQL commands.
While no specific APT groups are directly linked to this CVE at this time, the public disclosure and availability of a PoC make it attractive to various threat actors, including those seeking to steal data, deface websites, or establish a foothold for further attacks. CISA KEV status: Not listed.
Web Application Firewall (WAF) logs: Examine WAF logs for suspicious SQL injection attempts, such as the use of common SQL injection keywords (e.g., SELECT, UNION, OR, AND, ', --).
Database Activity Monitoring (DAM): Monitor database query logs for unusual or malicious SQL statements, especially those originating from the vulnerable application.
Intrusion Detection System (IDS) / Intrusion Prevention System (IPS) logs: Analyze IDS/IPS logs for signatures or rules that match known SQL injection patterns.
Application logs: Review application logs for error messages or unusual behavior related to database interactions, particularly those involving the editid parameter.
Network traffic analysis: Inspect network traffic for suspicious HTTP requests to /admin/property-details.php containing potentially malicious payloads in the editid parameter.
Implement parameterized queries or prepared statements: Use parameterized queries or prepared statements to separate SQL code from user-supplied data, preventing SQL injection.
Input validation and sanitization: Thoroughly validate and sanitize all user input, including the editid parameter, to ensure it conforms to expected formats and lengths. This includes escaping special characters.
Least privilege principle: Grant the database user account used by the application only the minimum necessary privileges to perform its tasks.
Web Application Firewall (WAF): Deploy a WAF to filter and block malicious requests before they reach the vulnerable application.
Regular security audits and penetration testing: Conduct regular security audits and penetration testing to identify and address vulnerabilities.
Keep software up-to-date: Ensure the application and all its dependencies are updated to the latest versions to patch known vulnerabilities.
Implement a robust logging and monitoring system to detect and respond to suspicious activity.
