Attacker Impact
An attacker who successfully exploits this vulnerability can execute arbitrary SQL commands against the backend database [S1]. This can lead to unauthorized access to sensitive data, modification or deletion of database records, and potentially complete compromise of the application's administrative credentials [S1]. Depending on the database configuration and privileges, an attacker might also be able to read local files or execute operating system commands on the hosting server [S1].
Root Cause
The vulnerability exists within the author.control.php script of GeniXCMS through version 0.0.8 [S1]. The application accepts user input via the type parameter and interpolates it directly into a SQL query without proper sanitization, validation, or parameterization [S1]. Because the input is concatenated directly into the SQL statement, the database interpreter cannot distinguish between the intended query structure and the attacker-supplied SQL commands [S1].
Concrete Fixes
To mitigate this vulnerability, it is recommended to upgrade GeniXCMS to a version newer than 0.0.8 where input is properly sanitized [S1]. Additionally, developers should modify the database interaction logic in author.control.php to use prepared statements (parameterized queries) via PHP Data Objects (PDO) or MySQLi [S1]. Implementing strict input validation and whitelisting on the type parameter to ensure it only accepts expected alphanumeric values before processing is also recommended [S1].
Detection Methodology
A security scanner could detect this vulnerability by identifying if the target is running GeniXCMS version 0.0.8 or lower [S1]. Alternatively, sending non-destructive SQL injection probes to the author.control.php endpoint via the type parameter and analyzing the HTTP response for database-specific error messages or observing differential application behavior can confirm the presence of the SQL injection vulnerability [S1].
