CVE-2025-14603 in vsDesk
Summary
by MITRE • 08/19/2026
The application component processes user-supplied parameters insecurely, passing them into SQL queries. This can enable blind SQL injection, potentially exposing database contents or causing the application to become unresponsive. Apply patch from vendor https://vsdesk.ru/ . Versions 14.0101 and on have the patch.

The identified vulnerability represents a classic instance of insecure direct object reference handling within an SQL query context, specifically manifesting as blind SQL injection. This flaw arises because the application component fails to properly validate or sanitize user-supplied parameters before incorporating them into database queries. Instead of using parameterized statements or prepared statements which separate code from data, the system directly concatenates input values into the SQL command string. This architectural oversight allows an attacker to inject malicious SQL syntax that alters the logic of the original query. In a blind injection scenario, the application does not return detailed error messages or direct database output in its HTTP responses, forcing the attacker to infer information based on subtle differences in response times or behavior rather than explicit data leakage.
The operational impact of this vulnerability is severe and multifaceted. Primarily, it grants an unauthorized actor the ability to exfiltrate sensitive data from the backend database, including user credentials, personal identifiable information, and proprietary business logic. Because the injection is blind, the exploitation process requires a more sophisticated approach where attackers use boolean-based or time-based techniques to deduce table structures and extract data character by character. Furthermore, as noted in the vulnerability description, this flaw can lead to denial of service conditions. By crafting queries that trigger complex computational operations on the database server, such as heavy joins or infinite loops via crafted inputs, an attacker can consume significant system resources, causing the application to become unresponsive and effectively disrupting availability for legitimate users.
From a classification perspective, this vulnerability aligns with CWE-89, which covers Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The specific manifestation described falls under blind injection techniques, often associated with ATT&CK technique T1059.004, specifically the use of command and scripting interpreters via database interfaces like ODBC or JDBC. This categorization highlights that while the vector is web-based, the underlying mechanism exploits the interpretation capabilities of the database management system itself. The lack of input validation means the application treats user input as executable code rather than data, violating fundamental security principles regarding trust boundaries between client and server components.
To mitigate this vulnerability, immediate remediation requires applying the vendor-provided patch available from vsdesk.ru for versions 14.0101 and later. This update likely implements proper parameterization of SQL queries or enhances input validation routines to neutralize special characters that could alter query logic. In addition to applying the software patch, organizations should enforce strict input validation on all user-supplied parameters, ensuring they conform to expected formats such as alphanumeric strings for specific fields while rejecting any unexpected symbols like single quotes or semicolons. Implementing a Web Application Firewall can also provide an additional layer of defense by detecting and blocking known SQL injection patterns in network traffic before they reach the vulnerable application component. Regular security audits and code reviews focusing on database interaction layers are essential to prevent similar flaws from being introduced during future development cycles.
