HP announced that it has discovered a critical vulnerability CVE-2023-1707 that affects about 50 models of HP Enterprise LaserJet and HP LaserJet Managed printers. Interestingly, there is no patch for this vulnerability yet, and the manufacturer promises to fix it in about three months.
The issue was rated 9.1 out of 10 on the CVSS scale, making it critical. But the good news is that exploitation is only possible in a limited context, as affected devices must be running FutureSmart firmware version 5.6 and have IPsec (Internet Protocol Security) enabled. FutureSmart allows users to operate and configure printers either from a control panel available on the device or from a browser via remote access.Let me remind you that we also wrote that RCE vulnerabilities threaten many HP printer models, and also that HP Fixed Critical Potential Worm Vulnerability in 150 Printer Models.
Additionally, information security specialists reported that Researchers found a vulnerability that affects millions of HP, Xerox and Samsung printers.
Exploitation of a bug may lead to information disclosure. That is, an attacker could gain access to sensitive information transferred between vulnerable HP printers and other devices on the network.
