CVE-2022-28721: RCE Flaw Found In Over 60 HP Printers Models
Hewlett Packard has disclosed two potentially dangerous vulnerabilities in the firmware of various enterprise printer models that could be abused by attackers to run arbitrary code on affected printer models remotely.
The vulnerability (CVE-2022-28721), rated as critical in severity with a 9.8 CVSS scale is a buffer overflow, caused by improper bounds checking that allows for the potential execution of arbitrary code remotely on affected over 60 printer models.
The security flaw affects more than 60 printer models ranging from HP inkjet printers, HP LaserJet Pro printers, and HP PageWide Pro printers. To exploit the CVE-2022-28721 flaw, a remote attacker could send a specially-crafted request to overflow a buffer and execute arbitrary code on the system.
The second flaw (CVE-2022-28722) rated as high in severity with a 7.1 CVSS scale is also a buffer overflow that allows a local attacker could overflow a buffer and execute arbitrary code on the system.
These vulnerabilities in more than 60 printers from HP demonstrate that any type of device that connects to a network can expand the perceived threat surface.
