Summary
SSA-953710: Vulnerabilities in the Network Communication Stack in Desigo Fire Safety UL and Cerberus PRO UL Fire Protection Systems

Notes

Summary
Several products used in Desigo Fire Safety UL and Cerberus PRO UL Fire Protection Systems contain buffer overflow vulnerabilities in the network communication stack. Successful exploitation of the vulnerabilities could allow an unauthenticated attacker, who gained access to the fire protection system network, to execute arbitrary code on the affected products (CVE-2024-22039) or create a denial of service condition (CVE-2024-22040, CVE-2024-22041). Product-specific impact of the individual vulnerabilities is documented in the chapter “Vulnerability Description”. Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations
As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment.
