Description

Supsystic Membership 1.4.7 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the 'search' and 'sidx' parameters. Attackers can send GET requests to the badges module with crafted payloads to extract sensitive database information using time-based blind or UNION-based SQL injection techniques.
