While recently upgrading my laptop with a new Solid State Drive (SSD), I installed a management utility that is used for SanDisk SSDs. A quick examination revealed a some potentially dangerous vulnerabilities in it.

Over five years ago, we published a blog detailing how a webshell’s backdoor code was hidden in an image file. With this method, an attacker inserts PHP backdoor code in the meta-data headers of an image to circumvent detection.
