| 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-2026-6004 is a critical SQL injection vulnerability found in the Simple IT Discussion Forum version 1.0, specifically in the /delete-category.php file. The issue arises because the cat_id parameter is not properly validated or sanitized before being used in SQL queries. This allows an attacker to inject malicious SQL code remotely without needing to authenticate.
Two main SQL injection techniques can be used: error-based SQL injection, which exploits error messages to extract data, and time-based blind SQL injection, which uses time delays to infer information from the database.
The vulnerability enables unauthorized access to the database, data leakage, modification or deletion of data, full system compromise, and potential service disruption.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive data, data leakage, and unauthorized modification or deletion of database contents.
Attackers can fully compromise the system and disrupt services, potentially causing business continuity issues.
Since exploitation requires no authentication, any remote attacker can exploit this flaw, increasing the risk and ease of attack.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the `cat_id` parameter in the `/delete-category.php` file for SQL injection flaws. Two common techniques are used:
- Error-based SQL Injection (MySQL >= 5.6): Inject payloads that trigger database error messages to extract data. Example payload: cat_id=6' AND GTID_SUBSET(CONCAT(0x71766a7071,(SELECT (ELT(8381=8381,1))),0x716a626a71),8381)-- tYTr
- Time-based Blind SQL Injection (MySQL < 5.0.12): Use time delay functions to infer data by observing response delays. Example payload: cat_id=6' AND 5786=BENCHMARK(5000000,MD5(0x47685043))-- sqsQ
Automated tools like sqlmap can be used to confirm the vulnerability and enumerate the database by targeting the `cat_id` parameter.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements with parameter binding to separate SQL code from user input, preventing injection.
- Apply strict input validation and filtering to ensure the `cat_id` parameter only accepts expected formats.
- Minimize database user permissions by avoiding the use of high-privilege accounts such as root or admin for routine database operations.
- Conduct regular security audits and code reviews to detect and fix vulnerabilities promptly.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in Simple IT Discussion Forum 1.0 allows unauthorized access, data leakage, and data modification without authentication. Such unauthorized access and potential data breaches can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and ensuring data integrity.
Failure to remediate this vulnerability could result in exposure of personal or sensitive data, violating confidentiality and integrity requirements mandated by these standards, potentially leading to legal penalties and loss of trust.
