Multiple SQL injection vulnerabilities in Blakord Portal 1.3.A Beta and earlier allow remote attackers to execute arbitrary SQL commands via the id parameter to an arbitrary component.
Blakord Portal 1.3.A Beta and earlier are vulnerable to multiple SQL injection flaws, allowing remote attackers to inject malicious SQL commands. Successful exploitation grants attackers the ability to read, modify, or delete sensitive data within the portal's database, potentially leading to complete system compromise and data breaches. This vulnerability poses a significant risk to organizations using the affected software.
Step 1: Identify Vulnerable Component: The attacker identifies a component within Blakord Portal that accepts an id parameter, such as a page, article, or user profile.
Step 2: Craft Malicious Payload: The attacker constructs a SQL injection payload designed to execute arbitrary SQL commands. This payload is embedded within the id parameter.
Step 3: Payload Delivery: The attacker sends a crafted HTTP request to the vulnerable component, including the malicious payload in the id parameter.
Step 4: Server-Side Execution: The Blakord Portal application receives the request and incorporates the attacker-supplied id parameter directly into an SQL query without proper sanitization.
Step 5: Database Interaction: The database server executes the modified SQL query, including the attacker's injected SQL commands.
Step 6: Exploitation & Data Breach: Depending on the injected SQL commands, the attacker can then read, modify, or delete data from the database, potentially leading to a complete system compromise and data exfiltration.
The vulnerability stems from insufficient input validation and sanitization of the id parameter used in various components of Blakord Portal. The application directly incorporates user-supplied data into SQL queries without proper escaping or filtering. This allows attackers to craft malicious SQL statements that are then executed by the database server. The root cause is a failure to implement parameterized queries or other secure coding practices to prevent the injection of arbitrary SQL code. The lack of input validation allows attackers to bypass security measures and manipulate the database's behavior. The specific flaw lies in the absence of proper sanitization of the id parameter before it's used in SQL queries. This allows attackers to inject malicious SQL code, such as '; DROP TABLE users; -- to delete the users table.
