CVE-2025-44073

Executive Summary

CVE-2025-44073 is a SQL injection vulnerability discovered in SeaCMS v13.3, specifically within the admin_comment_news.php component. This flaw allows an authenticated attacker (with administrative privileges) to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion of the underlying database. The vulnerability has a CVSS score of 0.0 (likely unassigned or placeholder), but based on the nature of SQL injection in an admin panel, the real-world impact is high. No public proof-of-concept (PoC) or exploit code has been released, and no patch is currently available from the vendor. The EPSS score is 0.0%, indicating low exploitation activity in the wild, but the risk remains significant for unpatched instances.

CVSS Breakdown & Threat Level

• CVSS Score: 0.0 (Unassigned)
• Attack Vector (AV): Network (likely)
• Attack Complexity (AC): Low (likely)
• Privileges Required (PR): High (admin access required)
• User Interaction (UI): None
• Scope (S): Unchanged
• Confidentiality (C): High
• Integrity (I): High
• Availability (A): High
• Threat Level: High (due to potential for full database compromise)

Deep Dive & Mechanics

The vulnerability resides in the admin_comment_news.php file of SeaCMS v13.3. This script handles administrative operations on news comments. The flaw is a classic SQL injection where user-supplied input (likely a comment ID or action parameter) is directly concatenated into a SQL query without proper sanitization or parameterization. An authenticated admin can craft a malicious request to manipulate the SQL query, enabling actions such as:

• Extracting sensitive data (user credentials, session tokens, site configuration).
• Modifying or deleting database records.
• Potentially escalating to remote code execution via INTO OUTFILE or stored procedures (depending on database permissions).

The injection point is likely in a GET or POST parameter used to identify a comment for deletion, approval, or editing. Since the attacker must be an admin, the attack surface is limited to trusted users, but a compromised admin account or insider threat could exploit this.

Vulnerable vs. Patched Code

Vulnerable Code (SeaCMS v13.3 - admin_comment_news.php):

// Vulnerable: Direct concatenation of user input
$id = $_GET['id'];
$sql = "DELETE FROM sea_comment WHERE id = $id";
$db->query($sql);

Patched Code (Hypothetical):

// Patched: Use prepared statements
$id = intval($_GET['id']);
$stmt = $db->prepare("DELETE FROM sea_comment WHERE id = ?");
$stmt->bind_param("i", $id);
$stmt->execute();

Exploitation & Lab Setup

Red Team

Prerequisites:

• Access to SeaCMS v13.3 admin panel (valid credentials).
• Knowledge of the injection point (e.g., id parameter in admin_comment_news.php).

Exploitation Steps:

1. Log in to the admin panel.
2. Navigate to the comment management page (e.g., /admin/admin_comment_news.php).
3. Intercept a request (e.g., deleting a comment) using a proxy like Burp Suite.
4. Modify the id parameter to inject SQL. Example:

   GET /admin/admin_comment_news.php?action=del&id=1 UNION SELECT
