Summary

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying file system of the device. This vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the file system and then accessing it through the web-based management interface. A successful exploit could allow the attacker to read arbitrary files from the file system of the underlying operating system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Vulnerability from github – Published: 2024-11-15 18:30 – Updated: 2024-11-15 18:30

Details

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying file system of the device. This vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the file system and then accessing it through the web-based management interface. A successful exploit could allow the attacker to read arbitrary files from the file system of the underlying operating system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
