Cisco Patches UCCX Flaw: Root for the Bold Hackers!
Cisco patched a critical flaw in its Unified Contact Center Express software, allowing attackers to play digital puppet master with root command execution. No workarounds exist, so grabbing the latest update is your best bet to avoid becoming an unwitting star of a hacker’s next big show.

Hot Take:
Cisco’s UCCX software had a flaw so critical, it might as well have been the star of its own action movie. You know, the kind where the villain is a root command executioner, and the hero is an update patch riding in on a white horse (or maybe a USB stick) to save the day. Thank goodness Cisco remembered to put on its metaphorical cape and patch up the issue before the bad guys turned our call centers into their personal playgrounds. Root privileges for everyone? Not on Cisco’s watch!
