sca-2026-0016Vulnerabilities Affecting SICK CorivaHub2026-10-16csaf · sick_psirtDE
SICK CorivaHub includes the third-party components Apache Tomcat and MapLibre GL, which are affected by two known vulnerabilities. These vulnerabilities include an improper input validation issue in Apache Tomcat and a vulnerability in MapLibre GL that could allow malicious behavior through custom GUIs. Under certain conditions, successful exploitation could affect the confidentiality, integrity and availability of the affected system. The attack surface associated with the Apache Tomcat vulnerability is significantly reduced by the default product configuration. Nevertheless, SICK recommends updating to CorivaHub 2026.1.2 to remediate both vulnerabilities.
