- →CVE-2021-22717 is exploitable remotely with low attack complexity (AV:N/AC:L/PR:L) via path traversal when processing config files in Schneider Electric C-Bus Toolkit v1.15.7 and prior — monitor for suspicious config file processing activity on C-Bus Toolkit installations ↗
- →No known public exploits specifically target these vulnerabilities as of the advisory date (April 15, 2021) ↗
- ·Affected product scope is limited to C-Bus Toolkit v1.15.7 and prior; only this version range is vulnerable to CVE-2021-22717 ↗
- ·The path traversal vulnerability is triggered specifically during config file processing, not general file operations — detection should focus on that attack surface ↗
- ·CVSS v3 score of 8.8 with network attack vector and low privilege requirement means the attack can be launched remotely by a low-privileged authenticated user ↗
