Details
A vulnerability in the upgrade component of Cisco AnyConnect Secure Mobility Client could allow an authenticated, local attacker with low privileges to read arbitrary files on the underlying operating system (OS) of an affected device. The vulnerability is due to insufficient file permission restrictions. An attacker could exploit this vulnerability by sending a crafted command from the local CLI to the application. A successful exploit could allow the attacker to read arbitrary files on the underlying OS of the affected device. The attacker would need to have valid user credentials to exploit this vulnerability.
