K15t Apps and Log4Shell (CVE-2021-44228)
Background
On Friday, a Remote Code Execution vulnerability in the popular log4j logging framework was published as CVE-2021-44228 and is now known as Log4Shell.
We became aware of this vulnerability the same day and have immediately assessed all potentially affected K15t marketplace apps.
As a result of this assessment, we only identified one app that was affected by the vulnerability: Scroll Viewport for Cloud
All other K15t apps are not affected by the vulnerability, or they use the logging infrastructure supplied by the Atlassian host application, which is generally considered non-vulnerable, although an insecure configuration can be created - see Atlassian’s FAQ.
Which K15t apps are affected by CVE-2021-44228?
Only Scroll Viewport for Cloud was affected by CVE-2021-44228. We've rolled out a fix on 12:00 pm CET, so Scroll Viewport for Cloud is no longer vulnerable to this attack. As Cloud apps update automatically, you don't have to do anything.
Please refer to the following Jira issue for further information: VPC-216
