Confluence Data Center, Confluence Server
This Critical severity org.apache.tomcat:tomcat-catalina Dependency vulnerability was introduced in version 6.10 of Confluence Data Center and Server.
This org.apache.tomcat:tomcat-catalina Dependency vulnerability, with a CVSS Score of 9.8 and a CVSS Vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H allows an unauthenticated attacker to expose assets in your environment susceptible to exploitation which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.
Atlassian recommends that Confluence Data Center and Server customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions:
- Confluence Data Center and Server 8.5: Upgrade to a release greater than or equal to 8.5.19
- Confluence Data Center and Server 9.2: Upgrade to a release greater than or equal to 9.2.1
See the release notes (https://confluence.atlassian.com/doc/confluence-release-notes-327.html). You can download the latest version of Confluence Data Center and Server from the download center (https://www.atlassian.com/software/confluence/download-archives).
The National Vulnerability Database provides the following description for this vulnerability: Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97.
The mitigation for CVE-2024-50379 was incomplete.
Users running Tomcat on a case insensitive file system with the default servlet write enabled (readonly initialisation
parameter set to the non-default value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which version of Java they are using with Tomcat:
- running on Java 8 or Java 11: the system property sun.io.useCanonCaches must be explicitly set to false (it defaults to true)
- running on Java 17: the system property sun.io.useCanonCaches, if set, must be set to false (it defaults to false)
- running on Java 21 onwards: no further configuration is required (the system property and the problematic cache have been removed)
Tomcat 11.0.3, 10.1.35 and 9.0.99 onwards will include checks that sun.io.useCanonCaches is set appropriately before allowing the default servlet to be write enabled on a case insensitive file system. Tomcat will also set sun.io.useCanonCaches to false by default where it can.
[CONFSERVER-99216] RCE (Remote Code Execution) org.apache.tomcat:tomcat-catalina Dependency in Confluence Data Center and Server
| Fix Version/s | New: 9.3.1 [ 110904 ] |
Please could someone from Atlassian confirm that this does not affect Confluence when running on Linux i.e. on a case sensitive filesystem ?

Hi. According to what we have read, this bug may not affect Linux. Is this true?
