CVE-2021-4088 [High] | SQL Injection in Data Loss Prevention

SQL injection vulnerability in Data Loss Protection (DLP) ePO extension 11.8.x prior to 11.8.100, 11.7.x prior to 11.7.101, and 11.6.401 allows a remote authenticated attacker to inject unfiltered SQL into the DLP part of the ePO database. This could lead to remote code execution on the ePO server with privilege escalation.
