Description

A vulnerability has been identified in POWER METER SICAM Q100 (All versions < V2.50), POWER METER SICAM Q100 (All versions < V2.50), POWER METER SICAM Q100 (All versions < V2.50), POWER METER SICAM Q100 (All versions < V2.50), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P850 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10), SICAM P855 (All versions < V3.10). Affected devices do not properly validate the EndTime-parameter in requests to the web interface on port 443/tcp. This could allow an authenticated remote attacker to crash the device (followed by an automatic reboot) or to execute arbitrary code on the device.
