CVE-2015-2177siemenssimatic_s7-300_cpu_firmware
EPSS score33.79%
Siemens SIMATIC S7-300 CPU devices allow remote attackers to cause a denial of service (defect-mode transition) via crafted packets on (1) TCP port 102 or (2) Profibus.CVE-2016-9158siemens agsimatic s7-300 cpu family+7EPSS score3.03%
A vulnerability has been identified in SIMATIC S7-300 CPU family (All versions), SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC S7-400 PN/DP V6 and below CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-400 PN/DP V7 CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-400 V6 and earlier CPU family (All versions), SIMATIC S7-400 V7 CPU family (All versions). Specially crafted packets sent to port 80/tcp could cause the affected devices to go into defect mode. A cold restart is required to recover the system.CVE-2016-9159siemens agsimatic s7-300 cpu family+9EPSS score1.54%
A vulnerability has been identified in SIMATIC S7-300 CPU family (All versions), SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC S7-400 PN/DP V6 and below CPU family (incl.

SIPLUS variants) (All versions). An attacker with network access to port 102/tcp (ISO-TSAP) or via Profibus could obtain credentials from the PLC if protection-level 2 is configured on the affected devices.CVE-2019-18336siemens agsimatic s7-300 cpu family (incl. related et200 cpus and siplus variants)+15EPSS score1.72%
A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V3.X.17), SIMATIC TDC CP51M1 (All versions < V1.1.8), SIMATIC TDC CPU555 (All versions < V1.1.1), SINUMERIK 840D sl (All versions < V4.8.6), SINUMERIK 840D sl (All versions < V4.94). Specially crafted packets sent to port 102/tcp (Profinet) could cause the affected device to go into defect mode. A restart is required in order to recover the system. Successful exploitation requires an attacker to have network access to port 102/tcp, with no authentication. No user interation is required. At the time of advisory publication no public exploitation of this security vulnerability was known.CVE-2019-10936siemensdevelopment/evaluation kits for profinet io: dk standard ethernet controller+139EPSS score2.07%
Affected devices improperly handle large amounts of specially crafted UDP packets.
This could allow an unauthenticated remote attacker to trigger a denial of service condition.CVE-2019-10923siemenscp1604_firmware+110EPSS score1.40%
An attacker with network access to an affected product may cause a denial of service condition by breaking the real-time synchronization (IRT) of the affected installation.
