Description

IBM Concert 1.0.0 through 2.3.1 is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify, or delete information in the back-end database.

  "executiveSummary": "IBM Concert, specifically versions 1.0.0 through 2.3.1, contains a critical SQL injection vulnerability. This security flaw stems from the improper sanitization of user-supplied input before it is processed by database queries.\nA remote, unauthenticated or authenticated attacker can leverage this vulnerability to inject malicious SQL commands into the backend database. Successful exploitation allows an attacker to bypass security controls to read, modify, delete, or exfiltrate sensitive data, potentially leading to a full compromise of the application's data integrity and confidentiality.\nThe vulnerability represents a significant risk to the organization as it grants unauthorized control over database interactions. Given that this is a remote attack vector, the potential for widespread data exposure or disruption is high, necessitating immediate prioritization of remediation efforts.",
  "technicalDetails": "The vulnerability resides within the input handling logic of the IBM Concert application, where unsanitized input is directly concatenated into dynamic SQL statements. This lack of parameterized queries or prepared statements allows an attacker to manipulate the query structure, effectively altering the intended logic of the database commands.\nThe attack flow initiates when an attacker sends a crafted request containing malicious SQL syntax to a vulnerable endpoint. By supplying input containing characters such as single quotes ('), semicolons (;), or SQL keywords (e.g., UNION, SELECT, DROP), the attacker can escape the intended data field and execute arbitrary commands. For instance, an attacker could append a UNION SELECT statement to extract data from auxiliary tables or inject a time-based payload to verify the vulnerability through inference.\nThe affected component is the application's database interaction layer. In versions 1.0.0 through 2.3.1, the application fails to utilize modern, secure coding patterns such as prepared statements with bind variables, which would otherwise ensure that user input is treated strictly as data and not executable code. The absence of robust input validation or server-side output encoding further exacerbates the risk.\nExploitation does not require elevated privileges in most scenarios, provided the endpoint is reachable from the network. Once the injection point is identified, an attacker can perform unauthorized CRUD (Create, Read, Update, Delete) operations. The impact extends beyond simple data theft; if the database user associated with the application service has excessive permissions, the attacker might be able to modify database configuration, escalate privileges within the application, or gain unauthorized access to other data objects stored in the same database instance. The persistent nature of data manipulation means that even after the initial attack, the state of the database may remain compromised, potentially affecting application logs, user metadata, or system configuration stored within the backend database."
