CVE-2015-4277 [MEDIUM] CWE-399 Cisco ASR 9000 Series Aggregation Services Routers tmp Files Denial of Service Vulnerability
Cisco ASR 9000 Series Aggregation Services Routers tmp Files Denial of Service Vulnerability
A vulnerability in Cisco ASR 9000 Series Aggregation Services Routers could allow an authenticated, local attacker to produce excessive tmp/*config files, causing the system to become unresponsive.
The vulnerability is due to the abrupt closure of the user's vty sessions after the commit/end in global configuration mode. An attacker could exploit this vulnerability by using methods to generate excessive tmp/*config files, causing the affected system's memory to be exhausted, resulting in a denial of service (DoS) condition.
Cisco has confirmed the vulnerability and released software updates.
To exploit this vulnerability, an attacker must authenticate and have local access to the targeted devi
