CVE-2019-25537

Root

Cause

The vulnerability is a time-based blind SQL injection in the Email parameter of loginaction.php. The application fails to properly neutralize special elements used in an SQL command (CWE-89), allowing attackers to inject arbitrary SQL code. This issue affects Netartmedia Event Portal version 2.0 and earlier [1].

Exploitation

An unauthenticated attacker can exploit this by sending a POST request to loginaction.php with a malicious payload in the Email field. The exploit uses time-based detection, such as the SLEEP() function, to infer database information byte by byte. No authentication or special privileges are required [1][2].

Impact

Successful exploitation allows an attacker to extract sensitive data from the database, including user credentials, personal information, and other stored data. The CVSS v4 vector indicates high confidentiality impact (VC:H), with low integrity impact (VI:L) [1].

Mitigation

As of the advisory, no official patch has been confirmed. Users should consider upgrading to a patched version if available, or implement input validation and parameterized queries to prevent SQL injection. The vulnerability has been publicly disclosed via Exploit-DB [2].
