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 execute arbitrary SQL commands. This could lead to complete system compromise, including data theft, unauthorized access, and potential server takeover. Immediate patching or mitigation is crucial to prevent exploitation.
Step 1: Identify Vulnerable Component: An 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 crafts a malicious SQL injection payload designed to execute arbitrary SQL commands. This payload is designed to manipulate the database query.
Step 3: Inject Payload: The attacker injects the crafted payload into the id parameter of the identified component via an HTTP request (e.g., GET or POST).
Step 4: Server-Side Execution: The Blakord Portal application receives the request and incorporates the attacker's payload directly into a SQL query without proper sanitization.
Step 5: Database Interaction: The database server executes the modified SQL query, which now includes the attacker's malicious commands.
Step 6: Data Exfiltration/Privilege Escalation: Depending on the payload, the attacker can then extract sensitive data (e.g., usernames, passwords), modify database records, or potentially gain control of the underlying system.
The vulnerability stems from insufficient input validation of the id parameter used in various Blakord Portal components. The application directly incorporates this user-supplied input into SQL queries without proper sanitization or escaping. This allows attackers to inject malicious SQL code, which is then executed by the database server. The root cause is a failure to implement parameterized queries or prepared statements, leading to a direct injection vulnerability. The lack of input validation allows for the construction of SQL statements that can alter the database's behavior, leading to data exfiltration, account takeover, and potentially remote code execution if the database server is configured to allow it.
Due to the age of the vulnerability, it's likely that various threat actors, including both opportunistic and more sophisticated groups, could exploit this. While specific APT attribution is difficult, any group seeking to gain initial access or escalate privileges on a vulnerable system would be a potential threat. This vulnerability is not listed on the CISA KEV at the time of this report, but it is a high-risk vulnerability due to its potential impact and ease of exploitation.
Web application firewall (WAF) logs showing suspicious SQL syntax in HTTP requests, particularly within the id parameter.
Database server logs revealing unusual query patterns or unexpected database activity.
Network traffic analysis identifying unusual HTTP requests with SQL injection payloads (e.g., common SQL injection keywords like 'SELECT', 'UNION', 'DROP', etc.) in the id parameter.
Intrusion Detection System (IDS) alerts triggered by known SQL injection signatures.
File integrity monitoring detecting changes to critical application files or database configuration files.
Patching: Upgrade to a patched version of Blakord Portal (if available). This is the most effective solution.
Input Validation: Implement robust input validation to sanitize and filter all user-supplied input, especially the id parameter. This includes whitelisting allowed characters and data types.
Parameterized Queries/Prepared Statements: Use parameterized queries or prepared statements to prevent SQL injection. This separates the SQL code from the user-supplied data.
Least Privilege: Configure the database user account used by Blakord Portal with the least privileges necessary to perform its functions.
Web Application Firewall (WAF): Deploy a WAF to filter malicious traffic and block SQL injection attempts.
Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities.
Database Hardening: Harden the database server by disabling unnecessary features and applying security best practices.
