CVE-2026-101108: Joomla Vehicle Manager SQLI Vulnerability

CVE-2026-101108 Overview

CVE-2026-101108 is an unauthenticated SQL injection vulnerability in the OrdaSoft Vehicle Manager (Free) extension for Joomla, affecting versions prior to 6.5.8. The flaw resides in site/vehiclemanager.php, which reads the order_field and order_direction sort parameters at three anonymous-reachable frontend entry points: the category listing, the search endpoint, and the all-vehicles listing. A sanitizing function applies real escaping to these values, but they are then placed into an unquoted ORDER BY clause where escaping provides no protection. Attackers can inject arbitrary SQL without authentication over the network.

Critical Impact
Unauthenticated remote attackers can extract database contents, including credentials and personally identifiable information, from any Joomla site running Vehicle Manager below 6.5.8.

Affected Products

OrdaSoft Vehicle Manager (Free) Joomla Extension versions prior to 6.5.8
Joomla sites exposing the Vehicle Manager category listing endpoint
Joomla sites exposing the Vehicle Manager search and all-vehicles listing endpoints

Technical Details for CVE-2026-101108

Vulnerability Analysis

The vulnerability is a classic SQL injection [CWE-89] in a sort-parameter code path. The Vehicle Manager component accepts two user-controlled parameters, order_field and order_direction, and appends them directly to an ORDER BY clause in a database query. Because the injected values are not wrapped in quotes, the escaping applied by the sanitizing function cannot neutralize SQL metacharacters. An attacker can supply subqueries, CASE expressions, or time-based payloads to enumerate arbitrary rows in the Joomla database.

All three vulnerable entry points are reachable without authentication. This allows blind or in-band extraction of session tokens, hashed administrator passwords stored in the #__users table, and any other data accessible to the Joomla database user. Successful exploitation typically leads to full site compromise once administrator credentials are recovered.

Root Cause

The root cause is misuse of escaping as a defense against SQL injection in a non-string context. Escaping functions protect quoted string literals by neutralizing quote characters. When user input is concatenated into an ORDER BY clause as a bare identifier, no quote boundary exists, and payloads composed of SQL keywords and operators pass through unmodified. The correct pattern is allow-listing sort columns and directions against a fixed set of expected values.

Attack Vector

Exploitation requires only an HTTP request to any of the three frontend endpoints in site/vehiclemanager.php. An attacker supplies a crafted order_field or order_direction value in the query string, using techniques such as boolean-based blind SQLi, UNION-based extraction, or SLEEP()-based timing inference. No user interaction, session, or privileged account is required. The vulnerability is remotely exploitable across the internet against any exposed Joomla site running an affected version.

No verified proof-of-concept code is published in the referenced advisory. See the OrdaSoft Website for vendor-issued extension updates.

Detection Methods for CVE-2026-101108

Indicators of Compromise

HTTP requests to Vehicle Manager frontend endpoints containing SQL keywords such as SELECT, UNION, SLEEP, BENCHMARK, or CASE WHEN in the order_field or order_direction parameters.
Unusually long response times on category listing, search, or all-vehicles listing pages, consistent with time-based blind SQL injection probing.
Web server access logs showing repeated requests to Vehicle Manager URLs with varying order_field values from a single source address.
Unexpected reads or errors in Joomla database logs referencing the #__users or Vehicle Manager tables originating from anonymous frontend sessions.

Detection Strategies

Deploy a web application firewall rule that inspects order_field and order_direction query parameters for SQL syntax and blocks non-allow-listed values.
Enable Joomla and MySQL slow-query and error logging, then alert on syntactically malformed ORDER BY clauses referencing Vehicle Manager tables.
Correlate frontend request patterns with database error responses to surface blind SQL injection attempts.

Monitoring Recommendations

Monitor outbound traffic from the Joomla host for signs of data exfiltration following suspicious frontend requests.
Track authentication events for Joomla administrator accounts and alert on logins from new IP addresses or geographies after suspected probing.
Audit the Joomla #__users and session tables for unexpected modifications or newly created privileged accounts.

How to Mitigate CVE-2026-101108

Immediate Actions Required

Upgrade the OrdaSoft Vehicle Manager (Free) extension to version 6.5.8 or later on all Joomla sites.
Rotate Joomla administrator passwords and invalidate active sessions after upgrading, assuming pre-patch exposure.
Review the #__users table for unauthorized accounts and remove any that were not provisioned by administrators.

Patch Information

OrdaSoft addresses this vulnerability in Vehicle Manager (Free) version 6.5.8. Administrators should obtain the update from the OrdaSoft Website and apply it through the standard Joomla extension update workflow. Verify the installed version in the Joomla administrator console after upgrading.

Workarounds

If immediate patching is not possible, restrict access to Vehicle Manager frontend URLs through IP allow-listing or by temporarily unpublishing the component.
Deploy a web application firewall rule that rejects requests where order_field or order_direction contain characters other than alphanumerics and underscores.
Enforce read-only database privileges on the Joomla application account where feasible to limit the impact of successful injection.
