Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2019-25694 is an SQL injection vulnerability (CWE-89) in Kados R10 GreenBee, where the user2reset parameter fails to properly sanitize input. This allows attackers to inject malicious SQL code directly into database queries. The vulnerability carries 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 with low integrity impact and no availability disruption.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted HTTP requests containing SQL payloads via the user2reset parameter. Successful exploitation enables manipulation of database queries, allowing extraction of sensitive information from the database or limited modification of data.
