The exploit targets web services via the TLS extension for heartbeat. [h](https://www.openssl.org/news/secadv_20140407.txt)[ttps://www.openssl.org/news/secadv_20140407.txt](https://www.openssl.org/news/secadv_20140407.txt) Most Pharos products are based upon Microsoft libraries, not OpenSSL. Pharos EDI and SignUp rely on Microsoft IIS. MobilePrint relies upon .NET Web-API. These systems use Microsoft SSL libraries, such as SChannel, not OpenSSL.

Each Development team is evaluating their non-Microsoft libraries to confirm whether any Pharos products are affected. Thus far, Development has finished their review of the following products and concluded that they are not affected. - Uniprint - All versions - Blueprint - All versions - MobilePrint - All versions - Omega PSX - Firmware 1.1.4 - Omega PS200 - Firmware 1.0.1 - Omega PS60 - Firmware 1.1.4 - Omega PS60B - Firmware 1.0.0 We'll continue to post updates to this article as we continue evaluating all of our products. ## Related - [Lexmark iMFP fails to connect to the Blueprint EDI Service.](/lexmark-imfp-fails-to-connect-to-the-blueprint-edi-service.md) - [Sentry SR25 - How to obtain a log file from the SR25 device.](/sentry-sr25-how-to-obtain-a-log-file-from-the-sr25-device.md) - [Blueprint: Test failed.
