A vulnerability in the image download process of the Cisco Unified Computing
System fabric interconnect could allow an authenticated, local attacker
to overwrite arbitrary files on the filesystem.
The
vulnerability occurs because the storage location is defined in the image
header. An attacker could exploit this vulnerability by modifying the
image header to specify a different directory and filename. A
successful exploit could allow the attacker to delete arbitrary files.
Cisco has confirmed the vulnerability in a security notice and released software updates.
To exploit this vulnerability, an attacker would need to authenticate and have local access to the targeted device, which may reside on trusted, internal networks. These access requirements limit the likelihood of a successful exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available
