Multiple vulnerabilities in Treck TCP/IP stack (Ripple20)

(Latest update: October 14, 2020)

A list of vulnerabilities called “Ripple20” affecting a network software library used in a large variety of connected devices have been recently disclosed by the JSOF security research group. Some of these vulnerabilities affecting this TCP/IP stack developed by Treck Inc. have been confirmed as critical by CERTs (Computer Emergency Response Teams), as they may allow remote code execution or expose sensitive information.

We have evaluated the exposure of bioMérieux products as per our continuous threat monitoring process and have identified that HP SL-M4020ND printers delivered with some of our commercial systems in the past are affected by Ripple20 vulnerabilities when used through network connectivity instead of USB. We recommend our customers  verify if they use networked HP SL-M4020ND printers with their bioMérieux systems and to update the printers’ firmware. More information and instruction are available in HP’s security advisory.

No other severe impact has been identified at this point and the present communication will be updated as appropriate.

Please contact your local bioMérieux representative if you have any question.
