Synopsis

The remote Atlassian Confluence host is missing a security update.

Description

The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in the CONFSERVER-96103 advisory.

 - When reading a specially crafted ZIP archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' zip package. (CVE-2021-36090)

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