Cisco IOS XE SD-WAN Software Path Traversal Vulnerability
Description
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to conduct path traversal attacks and obtain read access to sensitive files on an affected system. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to view arbitrary files on the affected system.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authenticated local attacker can read arbitrary files on Cisco IOS XE SD-WAN Software via path traversal due to insufficient input validation.
Vulnerability
A path traversal vulnerability exists in the command-line interface (CLI) of Cisco IOS XE SD-WAN Software. The flaw is due to insufficient validation of user-supplied input, allowing crafted requests to traverse directories. The vulnerability affects multiple releases of Cisco IOS XE SD-WAN Software; specific affected versions are detailed in the Cisco Security Advisory [1].
Exploitation
An attacker must be authenticated and have local access to the affected device. The attacker exploits the vulnerability by sending a specially crafted request through the CLI to the system. No further privileges or user interaction beyond authentication are required [1].
Impact
Successful exploitation grants the attacker read access to arbitrary files on the affected device, leading to unauthorized disclosure of sensitive information. The attacker obtains file contents without requiring higher-level permissions [1].
Mitigation
Cisco has released software updates that fix this vulnerability. Customers should upgrade to the earliest fixed release as indicated by the Cisco Software Checker or the advisory [1]. No workarounds are available, and the advisory strongly recommends upgrading.
