Cisco has shipped a critical bulletin to warn about a serious security hole in the Cisco Internet Streamer application, which is part of the Cisco Content Delivery System.
In an advisory, Cisco warned that exploitation of this vulnerability may allow a remote, unauthenticated attacker to obtain sensitive information, including password files and system logs.
The skinny:
The Cisco Internet Streamer application, part of the Cisco Content Delivery System, contains a directory traversal vulnerability on its web server component that allows for arbitrary file access. By exploiting this vulnerability, an attacker may be able to read arbitrary files on the device, outside of the web server document directory, by using a specially crafted URL.
An unauthenticated attacker may be able to exploit this issue to access sensitive information, including the password files and system logs, which could be leveraged to launch subsequent attacks.
The flaw carries a CVSS Base Score of 7.8.
