CVE-2026-78082 in SP Property Extension
Summary
by MITRE • 09/10/2026
Joomla Extension - joomshaper.com - Unauthenticated SQL Injection in Property Search and Map Filtering in SP Property < 4.1.4 - The property search and listing query builders assembled several WHERE and ORDER BY clauses (zipcode, sorting, price_range_dropdown, and psize_range_dropdown) by directly concatenating raw request parameters into SQL strings without quoting or type casting. An unauthenticated remote attacker could execute boolean-based or time-based blind SQL injection to extract sensitive data from the database.

The vulnerability identified in SP Property versions prior to 4.1.4 represents a critical security flaw within the Joomla extension ecosystem, specifically affecting how user input is processed during property search and map filtering operations. This component allows users to filter real estate listings based on various criteria such as zip codes, price ranges, and page sizes. The core technical deficiency lies in the construction of SQL queries where these specific parameters are directly concatenated into database strings without any form of sanitization, quoting, or type casting. By failing to validate or escape input from fields like zipcode, sorting preferences, price_range_dropdown, and psize_range_dropdown, the application exposes its underlying database structure to direct manipulation by external actors. This lack of proper data handling is a fundamental deviation from secure coding practices required for web applications interacting with relational databases.
From an operational perspective, this flaw enables unauthenticated remote attackers to perform both boolean-based and time-based blind SQL injection attacks. Because no authentication is required to trigger the vulnerable endpoints, the attack surface is significantly expanded, allowing any internet user to exploit the weakness without needing valid credentials. Boolean-based injections allow attackers to infer database contents by observing changes in application responses based on true or false conditions, while time-based injections rely on introducing delays in query execution to deduce data character by character. These techniques can be used to extract sensitive information stored within the Joomla database, including user passwords, administrative credentials, and potentially other proprietary business logic or customer data associated with property listings.
The classification of this vulnerability aligns closely with CWE-89, which denotes Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The specific mechanism here involves the direct concatenation of unsanitized user input into dynamic query strings, a pattern frequently cited in security audits and static analysis tools. Furthermore, this vulnerability facilitates data exfiltration through techniques documented under MITRE ATT&CK technique T1059, specifically Command Scripting or SQL Injection sub-techniques depending on the exact payload used. The ability to extract arbitrary data from the database backend can lead to a complete compromise of the Joomla instance if administrative credentials are retrieved and subsequently cracked using offline brute-force methods.
Mitigation for this vulnerability requires immediate action by both developers and system administrators. For existing deployments, upgrading SP Property to version 4.1.4 or later is the primary remediation step as it addresses these input validation flaws. In cases where an upgrade is not immediately feasible, implementing a Web Application Firewall with rules specifically tuned to detect SQL injection patterns in query parameters can provide temporary protection by blocking malicious payloads before they reach the application logic. Additionally, developers should refactor the affected code to utilize parameterized queries or prepared statements, which ensure that user input is treated strictly as data rather than executable code. Input validation routines must also be strengthened to enforce strict type checking and length constraints on all incoming parameters related to search filters.
