| CWE ID | Description |
|---|---|
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-7143 is a critical SQL injection vulnerability in version 1.0 of the 1000 Projects Portfolio Management System MCA, specifically in the admin/block_status.php and admin/unblock_me.php files.
The vulnerability arises from insecure handling of a base64-encoded GET parameter named "q", which represents a user registration ID (reg_id). This parameter is base64 decoded and directly concatenated into SQL UPDATE statements without any input validation, type checking, or use of prepared statements.
Because of this, attackers can inject arbitrary SQL code by crafting malicious base64-encoded payloads that, when decoded, manipulate the SQL query. This can be done remotely and the exploit is publicly available.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized modification of user account block statuses, such as blocking or unblocking arbitrary users.
Attackers can manipulate the database by executing arbitrary SQL commands, which may lead to privilege escalation, account takeover, denial of service by blocking legitimate users, and potential data breaches.
- Blocking all users by injecting a payload that updates all records.
- Dropping critical database tables, such as the user registration details table.
- Unblocking specific users without authorization.
Automated exploitation tools like sqlmap can be used to enumerate the database, extract credentials, and potentially fully compromise the system.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring HTTP requests to the vulnerable endpoint /admin/block_status.php for suspicious base64-encoded payloads in the 'q' parameter that could indicate SQL injection attempts.
You can use tools like sqlmap to test for SQL injection by targeting the 'q' parameter with crafted payloads.
- Example sqlmap command to test the vulnerability: sqlmap -u "http://target/admin/block_status.php?q=MTIz" --risk=3 --level=5 --dbs
- Use network monitoring or web server logs to search for suspicious base64 strings in the 'q' parameter such as those decoding to SQL injection payloads like "1' OR '1'='1" or "1'; DROP TABLE reg_details; --".
- Example grep command to find suspicious requests in web server logs: grep -i 'q=' /var/log/apache2/access.log | grep -E 'MScgT1IgJzEnPScx|MSc7IERST1AgVEFCTEUgcmVnX2RldGFpbHM7IC0t'
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include validating and sanitizing the base64-encoded 'q' parameter to allow only valid base64 characters, decoding it safely, and ensuring the decoded value is numeric before using it in SQL queries.
Use prepared statements with parameterized queries to prevent SQL injection instead of directly concatenating user input into SQL commands.
- Implement input validation using regex to restrict the 'q' parameter to base64 characters.
- Decode the 'q' parameter and verify it is numeric before using it in SQL queries.
- Replace vulnerable SQL query construction with prepared statements and parameter binding.
- Enforce least privilege on database users and separate admin and application database users.
- Add CSRF protection, request rate limiting, and deploy Web Application Firewall (WAF) rules to block malicious payloads.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the 1000 Projects Portfolio Management System MCA allows unauthorized attackers to manipulate database records, potentially leading to unauthorized access, modification, or deletion of sensitive user data.
Such unauthorized access and data manipulation can result in breaches of confidentiality, integrity, and availability of personal and sensitive information, which are core requirements in compliance frameworks like GDPR and HIPAA.
Therefore, exploitation of this vulnerability could lead to non-compliance with these regulations due to potential data breaches, unauthorized data modification, and failure to protect user data adequately.
