TITLE

SIMATIC S7-1200 and SIMATIC S7-1500 Vulnerable to resource exhaustion

Trust: 0.8

sources: JVNDB: JVNDB-2018-014528

DESCRIPTION

A vulnerability has been identified in SIMATIC S7-1200 (All versions), SIMATIC S7-1500 (All Versions < V2.6). An attacker could exhaust the available connection pool of an affected device by opening a sufficient number of connections to the device. Successful exploitation requires an attacker to be able to send packets to port 102/tcp of the affected device. No user interaction and no user privileges are required to exploit the vulnerability. The vulnerability, if exploited, could cause a Denial-of-Service condition impacting the availability of the system. At the time of advisory publication no public exploitation of this vulnerability was known. SIMATIC S7-1200 and SIMATIC S7-1500 Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Siemens SIMATIC S7-1200 and SIMATIC S7-1500 are programmable logic controllers (PLCs) from Siemens AG in small and medium-sized automation systems. Siemens SIMATIC S7 is prone to a denial-of-service vulnerability. Remote attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users
