Deeper analysis
CVE-2019-25704 is an SQL injection vulnerability (CWE-89) in Kados R10 GreenBee, specifically through the filter_user_mail parameter. This flaw allows attackers to inject malicious SQL code into database queries, potentially compromising the integrity of the underlying database. The affected software is Kados R10 GreenBee, 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.
Remote attackers require no privileges or user interaction to exploit this vulnerability. By sending crafted HTTP requests containing malicious SQL statements via the filter_user_mail parameter, they can manipulate database queries to extract sensitive information or modify data within the database.
