CVE-2019-25537 is a high-severity SQL Injection (CWE-89) vulnerability. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.6th 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
Netartmedia Event Portal 2.0 is affected by CVE-2019-25537, a time-based blind SQL injection vulnerability (CWE-89) in the loginaction.php component. The flaw arises from insufficient input validation on the Email parameter, enabling attackers to inject malicious SQL payloads into database queries. This issue 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 POST requests to loginaction.php with SQL injection payloads in the Email field. Successful exploitation allows manipulation of database queries, potentially enabling extraction of sensitive information from the underlying database through time-based blind techniques.
Advisories and exploit details are documented in references such as the Exploit-DB entry at https://www.exploit-db.com/exploits/46560 and the Vulncheck advisory at https://www.vulncheck.com/advisories/netartmedia-event-portal-sql-injection-via-loginaction-php, which provide proof-of-concept exploits but do not specify patches or mitigations in the available information.
