Title

Cisco Second Generation Integrated Services Routers和4451-X Integrated Services Router拒绝服务漏洞

Description

Cisco Second Generation Integrated Services Routers（ISR G2）和4451-X Integrated Services Router（ISR4451-X）都是美国思科（Cisco）公司的路由器产品。 Cisco ISR G2和ISR4451-X上的IOS和IOS XE Software中SM-1T3/E3固件存在拒绝服务漏洞，该漏洞源于程序未能正确的处理用户输入。远程攻击者可通过连接SM-1T3/E3模块控制器并输入字符串序列利用该漏洞造成ISR G2 Router或ISR4451-X上的SM-1T3/E3模块重新加载，导致拒绝服务。

Title

Cisco IOS and IOS XE Software SM-1T3/E3 Service Module Denial of Service Vulnerability

Summary

A vulnerability in the SM-1T3/E3 firmware on Cisco Second Generation Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated Services Router (ISR4451-X) could allow an unauthenticated, remote attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of user input. An attacker could exploit this vulnerability by first connecting to the SM-1T3/E3 module console and entering a string sequence. A successful exploit could allow the attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a DoS condition on an affected device.

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.
