CVE-2019-25531

Vulnerability

Analysis

The Netartmedia Deals Portal contains a SQL injection vulnerability in the Email parameter of loginaction.php. The application fails to properly neutralize special elements used in SQL commands, allowing an attacker to inject arbitrary SQL code into database queries. This flaw is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and affects the latest version of the software [1].

Exploitation

An unauthenticated attacker can exploit this vulnerability by sending a crafted POST request to loginaction.php with a malicious Email parameter. The proof-of-concept demonstrates a time-based blind SQL injection technique using SLEEP() to confirm the injection point. No authentication is required, and the attack can be performed remotely over the network [2].

Impact

Successful exploitation allows an attacker to manipulate database queries, potentially extracting sensitive information such as user credentials or other stored data. The vulnerability can also be used to bypass authentication mechanisms, granting unauthorized access to the application. The CVSS v4 score of 8.2 (High) reflects the low attack complexity and high confidentiality impact [1].

Mitigation

As of the publication date, no official patch has been released by Netartmedia. Users are advised to apply input validation and parameterized queries to mitigate the risk. The vendor has not responded to the disclosure, and the product may be end-of-life [1][2].
