VAR-202102-0551

Vulnerability from variot - Updated: 2023-12-18 14:00

Multiple vulnerabilities in the ingress packet processing function of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Cisco IOS XR The software contains a resource management vulnerability.Denial of service (DoS) It may be put into a state. The vulnerability is caused by the software's incorrect allocation of resources, and an attacker can exploit this vulnerability by sending a specific packet stream to the affected device. Successful exploitation of this vulnerability could allow an attacker to cause the enf_broker process to leak system memory. Over time, this memory leak could cause the enf_broker process to crash, potentially causing system instability and the inability to process or forward traffic through the affected device

Detection rules are retrieved from Rulezet.

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.
