VAR-202010-0448
Vulnerability from variot - Updated: 2023-12-18 13:32An issue was discovered in QSC Q-SYS Core Manager 8.2.1. By utilizing the TFTP service running on UDP port 69, a remote attacker can perform a directory traversal and obtain operating system files via a TFTP GET request, as demonstrated by reading /etc/passwd or /proc/version. QSC Q-SYS is a device used in signal processing from QSC Corporation of the United States. The device is used in audio information processing and information exchange, and can be used in conferences, teachers, lecture halls and other multi-person conference scenarios. Attackers can use this vulnerability to traverse TFTP related directories
