VAR-200210-0275

Vulnerability from variot - Updated: 2025-04-03 22:14

Cisco Virtual Private Network (VPN) Client software 2.x.x and 3.x before 3.0.5 allows remote attackers to cause a denial of service (crash) via TCP packets with source and destination ports of 137 (NETBIOS). It is possible for a remote attacker to exploit this condition to shut down a connection that the client has initiated by sending a NETBIOS packet to port 137 of the host running the client. It can be used under the Microsoft Windows operating system, and can also be used under the Linux operating system. CISCO designated this vulnerability number as: CSCdt35749

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.
