Vulnerability from variot - Updated: 2024-11-23 22:12

A vulnerability in the TCP ingress handler for the data interfaces that are configured with management access to Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an increase in CPU and memory usage, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient ingress TCP rate limiting for TCP ports 22 (SSH) and 443 (HTTPS). An attacker could exploit this vulnerability by sending a crafted, steady stream of TCP traffic to port 22 or 443 on the data interfaces that are configured with management access to the affected device. Cisco Firepower Threat Defense (FTD) The software contains a resource management vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Exploiting this issue allows remote attackers to cause a denial-of-service condition due to increase in CPU and memory usage. This issue is being tracked by Cisco Bug ID CSCvf95761, CSCvg76064, CSCvk35736, CSCvn51149

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.
