Atlassian Confluence 4.0 < 7.19.19 / 7.20.x < 8.5.4 / 8.6.x < 8.6.1 / 8.7.x < 8.7.1 (CONFSERVER-94510)

high Nessus Plugin ID 191094


The remote Atlassian Confluence host is missing a security update.


The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in the CONFSERVER-94510 advisory.

- Use of Java's default temporary directory for file creation in `FileBackedOutputStream` in Google Guava versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the machine with access to the default Java temporary directory to be able to access the files created by the class. Even though the security vulnerability is fixed in version 32.0.0, we recommend using version 32.0.1 as version 32.0.0 breaks some functionality under Windows. (CVE-2023-2976)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to Atlassian Confluence version 7.19.19, 8.5.4, 8.6.1, 8.7.1 or later.
