The bug could allow hackers to remotely access sensitive information
In a nutshell: Dozens of HP printers are vulnerable to a security issue that could potentially allow attackers to access sensitive information. The company is aware of the problem and is working on an update that will be rolled out later this year. In the meantime, HP is suggesting that users downgrade the firmware version of the affected models as a temporary workaround to mitigate the issue.
In brief: Several HP enterprise devices are running firmware containing as many as six unpatched security holes that allow arbitrary code execution. Some of them are at least a year old, and researchers publicly disclosed all of them over a month ago. As of this writing, all remain unpatched.
