3Description
A vulnerability has been identified in CPCI85 Central Processing/Communication (All versions < V26.10), SICORE Base system (All versions < V26.10.0). The affected application contains an out-of-bounds write vulnerability while parsing specially crafted XML inputs. This could allow an unauthenticated attacker to exploit this issue by sending a malicious XML request, which may cause the service to crash, resulting in a denial-of-service condition.
Analysis
Out-of-bounds write vulnerabilities in Siemens CPCI85 Central Processing/Communication and SICORE Base system (versions below V26.10) allow unauthenticated remote attackers to crash critical industrial control system services through maliciously crafted XML requests, resulting in denial-of-service conditions. CISA's SSVC framework marks this as automatable with partial technical impact, though no public exploit has been identified at time of analysis. …

Remediation
Within 24 hours: Inventory all CPCI85 and SICORE Base deployments and identify current versions; confirm systems running versions below V26.10 and assess network exposure. Within 7 days: Implement network-level input filtering for malformed XML requests targeting affected systems and restrict remote access to administrative interfaces using firewall rules or network segmentation. …
