Deeper analysis
NoviSmart CMS is affected by CVE-2019-25439, an SQL injection vulnerability (CWE-89) that enables remote attackers to execute arbitrary SQL queries. The flaw occurs through the injection of malicious code via the Referer HTTP header field, with a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact, low integrity impact, and no availability impact in the vector, though denial of service is noted as possible.
Unauthenticated remote attackers can exploit this vulnerability by crafting HTTP requests with time-based SQL injection payloads in the Referer header. Successful exploitation allows extraction of sensitive database information or disruption via denial of service, requiring no user interaction or privileges.
