This vulnerability in osTicket's search functionality allows for SQL injection attacks. Authenticated attackers can leverage specific parameters within the search feature to execute unauthorized SQL commands. This vulnerability can lead to unintended database manipulations, which may expose or alter sensitive data within the application. Exploitation of this flaw can compromise the integrity and confidentiality of the data stored within the osTicket system.

The vulnerability is located in the “Search” functionality within the “tickets.php” page of osTicket. By using specific URL parameters, such as "keywords" and "topic_id," an attacker can inject malicious SQL commands. When executed, these commands can manipulate the database by accessing unintended tables or altering data. This issue arises due to insufficient validation of input parameters in search queries. As a result, the osTicket platform becomes susceptible to SQL injection, allowing unauthorized database access.

If exploited, this vulnerability can allow attackers to read or modify sensitive information within the database, including customer support tickets. It can potentially enable unauthorized data access, leading to data breaches. Additionally, attackers could alter critical data, compromising the accuracy of information stored in osTicket.
