Severity Atlassian rates the severity level of this vulnerability as high, according to the scale published in our Atlassian severity levels. The scale allows us to rank the severity as critical, high, medium, or low. Depending on the environment the Jira instance is deployed in, the impact of this bug varies. For example, when deployed in AWS, it could leak sensitive credentials. This is our assessment and you should evaluate its applicability to your own IT environment. Acknowledgements We would like to acknowledge Shubham Shah and Dylan Pindur of ssetnote for finding this vulnerability. Fix To address this issue, we have released: Jira Core Server, Jira Software Server, and Jira Software Data Center versions: 8.13.22 8.20.10 8.22.4 9.0.0 Jira Service Management Server and Data Center versions: 4.13.22 4.20.10 4.22.4 5.0.0 You can download the latest versions from the download pages for Jira Core, Jira Software, or Jira Service Management. Please note, these are the first versions that include the fix for CVE-2022-26135. More current bug fix releases are available for the releases listed above. Atlassian recommends upgrading to the most current bug fix version. Mitigation Installing a fixed version of Jira or Jira Service Management is the surest way to remediate CVE-2022-26135. If you are unable to immediately upgrade Jira or Jira Service Management, then as a temporary workaround, you can manually upgrade Mobile Plugin for Jira Data Center and Server (com.atlassian.jira.mobile.jira-mobile-rest) to the versions specified in this section (or disable the plugin). The following versions of the Mobile Plugin for Jira app contain a fix for this issue: 3.1.5 (only compatible with Jira 8.13.x and JSM 4.13.x) 3.2.15 (only compatible with Jira 8.20.x - 8.22.x, only compatible with JSM 4.20.x - 4.22.x) If you’re either on Jira 8.13.x or JSM 4.13.x and have previously upgraded beyond the default app version of 3.1.x, upgrading the app to the fixed 3.1.5 version will effectively roll back any bug-fixes and features introduced in later versions, including JSM support. How to upgrade the app to the fixed 3.1.5 version (from 3.2.x) Download the fixed version (3.1.5) of the app (you’ll save this as a JAR file) from the Atlassian Marketplace During a maintenance window Shut down Jira (all nodes if you have Data Center installed) Remove plugin..jira-mobile-rest-3.2.x.jar from: Server: /plugins/installed-plugins Data Center: /plugins/installed-plugins Start Jira Navigate to Admin > Manage Apps Select Upload app Select the JAR file you downloaded in Step 1 How to upgrade the app Scenario A: User-installed apps If you find the “Mobile Plugin for Jira” app located in the User-installed apps section, you can just click Update to get the latest version. Scenario B: System apps If you find the “Mobile Plugin for Jira” app located in the System apps section, follow these instructions to manually update the app (no restart required!): Download a fixed version of the app (you’ll save this as a JAR file) from the Atlassian Marketplace that is compatible with your Jira version During a maintenance window: Navigate to Admin > Manage Apps Select Upload app Select the JAR file you downloaded in Step 1 After the install, the new version will be displayed as a user-installed app instead of a system app. The previous JAR file can remain in the directory /atlassian-jira/WEB-INF/atlassian-bundled-plugins without further action.
