CVE-2015-4244
HighSummary
The boot implementation on Cisco ASR 5000 and 5500 devices with software 14.0 allows local users to execute arbitrary Linux commands by leveraging administrative privileges for storage of these commands in a Compact Flash (CF) file.
Risk Assessment
Exploitation of this vulnerability may lead to unauthorized access to the system and potential takeover of the device by local users.
Recommendation
