FKIE_CVE-2018-0282
Vulnerability from fkie_nvd - Published: 2019-01-10 00:29 - Updated: 2026-06-17 01:30
Severity
Summary
A vulnerability in the TCP socket code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a state condition between the socket state and the transmission control block (TCB) state. While this vulnerability potentially affects all TCP applications, the only affected application observed so far is the HTTP server. An attacker could exploit this vulnerability by sending specific HTTP requests at a sustained rate to a reachable IP address of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition on an affected device.

"value": "A vulnerability in the TCP socket code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a state condition between the socket state and the transmission control block (TCB) state. While this vulnerability potentially affects all TCP applications, the only affected application observed so far is the HTTP server. An attacker could exploit this vulnerability by sending specific HTTP requests at a sustained rate to a reachable IP address of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition on an affected device."

La vulnerabilidad se debe a una condici\u00f3n de estado entre el estado socket y el estado de bloqueo de control de transmisi\u00f3n (TCB). Aunque esta vulnerabilidad podr\u00eda afectar a todas las aplicaciones TCP, la \u00fanica que se ha visto afectada hasta la fecha es el servidor HTTP. Un atacante podr\u00eda explotar esta vulnerabilidad enviando peticiones HTTP espec\u00edficas, a una velocidad constante, a una direcci\u00f3n IP localizable del software afectado. Si se explota con \u00e9xito, podr\u00eda permitir que el atacante consiguiera el reinicio del dispositivo afectado, provocando una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado."

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.
