We have now confirmed that this is not the case. Cryoserver customers pre-version 9.5 should nevertheless schedule an upgrade at some point in the future as good practice. --- **13/12/2021 1400hrs** On Friday 10th December, Apache announced a critical vulnerability within the LOG4J logging library for Java, called Log4Shell or LogJam. At 10/10 severity, this is comfortably one of the most serious IT vulnerabilities to have been discovered in recent memory, as Log4J is often installed on both Linux and Windows systems either directly, or often as a requirement of another package or system. Log4J is included on servers built by Cryoserver. **All our Cloud services** Are not vulnerable to CVE-2021-44228 **On-premises versions of Cryoserver on or above v.9.5.0** v9.5.0 released in January 2021 are not vulnerable to CVE-2021-44228 **Versions prior to v9.5.0 are partially vulnerable, as described below.** CVE-2021-44228 Attack Vectors: Please see: [https://www.lunasec.io/docs/blog/log4j-zero-day/](https://www.lunasec.io/docs/blog/log4j-zero-day/?utm_source=hs_email&utm_medium=email&utm_content=2&_hsenc=p2ANqtz-8--Hoqz3UR1BY6fd0Kn7UqWqN70O-DtRopa7UhoJRxYaDpEOgQ8-rXPlUUN4qrgMFRpYha2astfE8L0zIUxW4eQjTX4g&_hsmi=2) **Web Site Attack Vector** The attacker uses the public website to initiate the attack. No versions of Cryoservers' are vulnerable to this attack vector. **Back-End Attack Vector** The administrator of Cryoserver has set up an outbound connection to an LDAP server that is under the control of an attacker. The attacker manipulates the remote LDAP server to initiate the attack. > Cryoserver v9.5.0 and above is not vulnerable to this attack vector. As a next step, please email help@cryoserver.com if you have any concerns and/or wish to upgrade to our current 9.6 release. ## Read *More* [ ![TTDSG: Germany’s new data privacy law](https://cynical-zorilla.transforms.svdcdn.com/production/photo-1618259278412-2819cbdea4dc-cropentropycstinysrgbfitmaxfmjpgixidMnwxMTc3M3wwfDF8c2VhcmNofDh8fGdlcm1hbnl8ZW58MHx8fHwxNjQ4NDYyMzI0ixlibrb-1.2.1q80w2000.jpg?w=1024&h=512&q=100&fm=webp&fit=crop&dm=1727093443&s=2c0b8bbeb21c25e3e7699f1734260ca7) Sep 23, 2024## TTDSG: Germany’s new data privacy law ### BackgroundGermany is a pioneer in data privacy protection.
