CVE-2026-93484 Details
Description
Znuny through 7.3.6 constructs a ticket-search database query by directly concatenating user-supplied input into the SQL statement. This lack of proper sanitization or the use of parameterized queries allows an attacker to inject arbitrary SQL commands, leading to data theft, modification, or denial of service. Specifically this is in Kernel::System::Ticket::TicketSearch and Kernel::System::Ticket::ArticleSearchIndex::DB via the ContentSearch parameter. The parameter is expected to be either "AND" or "OR", but its value was concatenated directly into the generated SQL query without validation.
A SQL injection vulnerability has been identified in Znuny versions 6.5.1 prior to 6.5.24, 7.3.1 prior to 7.3.6, and all versions in the 6.0 through 7.2 range. The vulnerability arises in the ticket search functionality, specifically within the 'Kernel::System::Ticket::TicketSearch' and 'Kernel::System::Ticket::ArticleSearchIndex::DB' components. The issue is caused by the 'ContentSearch' parameter, which is intended to receive values of 'AND' or 'OR'. However, the parameter's value was directly concatenated into the SQL query without proper validation, allowing for arbitrary SQL command injection. This lack of sanitization could lead to data theft, unauthorized modification, or a denial-of-service condition.
Users can upgrade to Znuny LTS 6.5.25 or Znuny 7.3.7 to address this vulnerability.
