Mitigation

Siemens Releases Security Updates for Multiple Vulnerabilities in APOGEE, TALON and Desigo PXC/PXM Products

Siemens has identified multiple vulnerabilities across its APOGEE, TALON and Desigo PXC/PXM product lines. Four CVEs (CVE-2026-102073 through CVE-2026-102076) affect BACnet and P2 Ethernet implementations in APOGEE MBC, MEC, PXC Compact, PXC Modular and TALON TC products, potentially enabling denial of service conditions. A fifth CVE, CVE-2026-89208, affects various Desigo PXC and PXM models and involves improper input validation that could allow unauthenticated remote attackers to trigger memory reads outside intended packet boundaries. Siemens has released updated versions and recommends network segmentation as a mitigation where fixes are not yet available.
