A critical firmware vulnerability has been discovered in over 100 Lexmark printer models, making it possible for attackers to infiltrate devices and potentially compromise them permanently. This incident highlights the ongoing need for reliable print security measures to protect business networks.
The warning came directly from Lexmark, with reports indicating that the security flaw in the firmware allows attackers to infiltrate printer devices after an initial breach. Further, the vulnerability could allow an attacker to rewrite the firmware itself, posing a risk of permanent device compromise. While the vulnerability does not initiate an intrusion, Lexmark rates it as critical due to the potential for severe damage once access is gained.
Over 100 Lexmark printer models are affected. Firmware patches are available for the 120 affected printer models, and these can be found in a list published by Lexmark. These patches can be downloaded from Lexmark's support website.
Businesses using these models should update the firmware on their affected printers immediately to maintain the security of their systems.
