Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
USOC is an open source CMS with a focus on simplicity. In affected versions USOC allows for SQL injection via register.php. In particular usernames, email addresses, and passwords provided by the user were not sanitized and were used directly to construct a sql statement. Users are advised to upgrade as soon as possible. There are not workarounds for this issue.
CWE-89 - SQL Injection
Structured Query Language (SQL) injection attacks are one of the most common types of vulnerabilities. They exploit weaknesses in vulnerable applications to gain unauthorized access to backend databases. This often occurs when an attacker enters unexpected SQL syntax in an input field. The resulting SQL statement behaves in the background in an unintended manner, which allows the possibility of unauthorized data retrieval, data modification, execution of database administration operations, and execution of commands on the operating system.
