CVE-2017-7681 in OpenMeetings
Summary
by MITRE
Apache OpenMeetings 1.0.0 is vulnerable to SQL injection. This allows authenticated users to modify the structure of the existing query and leak the structure of other queries being made by the application in the back-end.

Apache OpenMeetings version 1.0.0 contains a critical SQL injection vulnerability that affects the application's database interaction mechanisms. This vulnerability exists within the application's query processing logic where user-supplied input is not properly sanitized before being incorporated into database queries. The flaw allows authenticated users to manipulate the structure of existing database queries through crafted input parameters, potentially enabling them to extract sensitive information from the database backend.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization within the application's database access layers. When authenticated users submit data that is subsequently processed by the application's SQL query builders, the system fails to properly escape or parameterize user input before incorporating it into database commands. This creates an environment where malicious input can alter the intended query structure and potentially expose internal database schemas or data through error messages and query results.
The operational impact of this vulnerability extends beyond simple data leakage to encompass potential unauthorized data modification and system compromise. An authenticated attacker can leverage this weakness to extract database schema information, user credentials, and other sensitive data stored within the application's backend systems. The vulnerability particularly affects the application's ability to maintain data integrity and confidentiality, as it allows for the manipulation of database structures that could lead to more severe security breaches. This issue represents a significant concern for organizations relying on Apache OpenMeetings for collaborative environments where user authentication is required.
Security practitioners should address this vulnerability through immediate patching of the Apache OpenMeetings application to version 3.0.0 or later, which contains the necessary fixes for SQL injection protections. Additionally, implementing proper input validation and parameterized query mechanisms should be enforced throughout the application's database interaction layers. Organizations should also consider deploying web application firewalls to monitor and filter suspicious database query patterns and implement comprehensive database access logging to detect potential exploitation attempts. The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws, and represents a technique commonly categorized under ATT&CK tactic TA0006 (Credential Access) and technique T1078 (Valid Accounts) for unauthorized database access through legitimate user credentials.
