TITLE

CodeMeter  Vulnerability in accessing buffers with improper length values in

Trust: 0.8

sources: JVNDB: JVNDB-2020-011219

DESCRIPTION

Multiple memory corruption vulnerabilities exist in CodeMeter (All versions prior to 7.10) where the packet parser mechanism does not verify length fields. An attacker could send specially crafted packets to exploit these vulnerabilities. CodeMeter There is a vulnerability in accessing the buffer with an improper length value.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Siemens SIMATIC WinCC OA (Open Architecture) is a set of SCADA system of Siemens (Siemens), Germany, and it is also an integral part of HMI series. The system is mainly suitable for industries such as rail transit, building automation and public power supply. Information Server is used to report and visualize the process data stored in the Process Historian. SINEC INS is a web-based application that combines various network services in one tool. SPPA-S2000 simulates the automation component (S7) of the nuclear DCS system SPPA-T2000. SPPA-S3000 simulates the automation components of DCS system SPPA-T3000. SPPA-T3000 is a distributed control system, mainly used in fossil and large renewable energy power plants. Many Siemens products have memory corruption vulnerabilities
