Exploitability
| CWE ID | Description |
|---|---|
| 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. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'phpMyChat Plus version 1.98 contains a SQL injection vulnerability in the deluser.php page through the pmc_username parameter.'}, {'type': 'paragraph', 'content': 'This vulnerability allows attackers to manipulate database queries by injecting malicious SQL code into the username field.'}, {'type': 'paragraph', 'content': 'Attackers can exploit this using multiple SQL injection techniques including boolean-based blind, error-based, and time-based blind SQL injection to extract sensitive information from the database.'}, {'type': 'paragraph', 'content': "The vulnerability was demonstrated by intercepting POST requests and using tools like sqlmap to extract user data from the database, specifically targeting the 'c_reg_users' table."}] [1]
How can this vulnerability impact me? :
This vulnerability can allow attackers to extract sensitive user data from the database without authorization.
Because the vulnerability allows for remote exploitation without any privileges or user interaction, it poses a high risk of data breach.
The attacker can manipulate database queries to access confidential information, potentially leading to identity theft, unauthorized access, or further attacks on the system.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
