VAR-201606-0022
Vulnerability from variot - Updated: 2023-12-18 13:14Siemens SIMATIC S7-300 Profinet-enabled CPU devices with firmware before 3.2.12 and SIMATIC S7-300 Profinet-disabled CPU devices with firmware before 3.3.12 allow remote attackers to cause a denial of service (defect-mode transition) via crafted (1) ISO-TSAP or (2) Profibus packets. The Siemens SIMATIC S7-300 CPU is a modular universal controller for the manufacturing industry from Siemens. A denial of service vulnerability exists in the Siemens SIMATICS7-300CPU family of devices. An attacker exploits a vulnerability to initiate a denial of service attack under certain conditions, that is, by sending a carefully crafted packet to a 102/TCP (ISO-TSAP) port or a fieldbus Profibus, causing the device to enter a failure mode, and a cold boot can restore the system. Siemens SIMATIC S7-300 CPU is prone to a denial-of-service vulnerability. Remote attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users. The following products and versions are affected: Versions prior to SIMATIC S7-300 CPUs with Profinet support 3.2.12 Versions prior to SIMATIC S7-300 CPU without Profinet support 3.3.12

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
