CVE-2015-6403

Name of the Vulnerable Software and Affected Versions Cisco Small Business SPA30x, SPA50x, SPA51x phones version 7.5.7

Description The issue is related to the TFTP implementation, which fails to properly validate the integrity of firmware-image files. This allows local users with shell access to load malicious firmware images.

Recommendations For version 7.5.7, update to a newer version that contains a fix for this issue, as the current version allows local users to load Trojan horse images by exploiting the improper validation of firmware-image file integrity.
