VAR-200210-0273

Vulnerability from variot - Updated: 2025-04-03 22:16

The LAN-to-LAN IPSEC capability for Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.4, allows remote attackers to cause a denial of service via an incoming LAN-to-LAN connection with an existing security association with another device on the remote network, which causes the concentrator to remove the previous connection. Cisco has reported a security vulnerability in VPN 3000 series concentrator devices. The vulnerability is related to handling of incoming LAN-to-LAN IPSEC tunnel connections. According to Cisco, this behaviour may be exploitable as a denial of service attack. Furthermore, affected devices do not ensure that the data transmitted across a LAN-to-LAN IPSEC tunnel is sourced from the appropriate network. The implications of this potentially separate issue are not yet known. There are loopholes in the LAN-to-LAN IPSEC capability of Cisco VPN 3000 Concentrator 2.2.x and versions 3.x before 3.5.4

Cisco has reported a security vulnerability in VPN 3000 series concentrator devices.  The vulnerability is related to handling of incoming LAN-to-LAN IPSEC tunnel connections.  According to Cisco, this behaviour may be exploitable as a denial of service attack. \nFurthermore, affected devices do not ensure that the data transmitted across a LAN-to-LAN IPSEC tunnel is sourced from the appropriate network.  The implications of this potentially separate issue are not yet known. There are loopholes in the LAN-to-LAN IPSEC capability of Cisco VPN 3000 Concentrator 2.2.x and versions 3.x before 3.5.4",

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.
