Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
An issue was discovered in Ampache through 3.9.1. The search engine is affected by a SQL Injection, so any user able to perform lib/class/search.class.php searches (even guest users) can dump any data contained in the database (sessions, hashed passwords, etc.). This may lead to a full compromise of admin accounts, when combined with the weak password generator algorithm used in the lostpassword functionality.
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.
