TITLE

Lack of Freeing Resources After Valid Lifetime Vulnerability in Multiple Siemens Products

Trust: 0.8

sources: JVNDB: JVNDB-2022-013266

DESCRIPTION

A vulnerability has been identified in CP-8000 MASTER MODULE WITH I/O -25/+70°C (All versions < CPC80 V16.30), CP-8000 MASTER MODULE WITH I/O -40/+70°C (All versions < CPC80 V16.30), CP-8021 MASTER MODULE (All versions < CPC80 V16.30), CP-8022 MASTER MODULE WITH GPRS (All versions < CPC80 V16.30). When using the HTTPS server under specific conditions, affected devices do not properly free resources. This could allow an unauthenticated remote attacker to put the device into a denial of service condition. Siemens' SICAM A8000 CP-8000 firmware, SICAM A8000 CP-8021 firmware, SICAM A8000 CP-8022 A vulnerability exists in firmware for lack of freeing resources after valid lifetime.Service operation interruption (DoS) It may be in a state. The SICAM A8000 RTU (Remote Terminal Unit) series is a modular device family for remote control and automation applications in all areas of energy supply
