Finding Confluence servers (yet, again) with runZero

, by HD Moore

An actively exploited zero-day has surfaced in popular wiki software Confluence. Deemed “critical” in severity with a CVSS score of 10 out of 10, this vulnerability affects most supported versions of Confluence Server and Confluence Data Center running 8.0.0 or later. Hosted instances within Atlassian Cloud and versions prior to 8.0.0 are reportedly protected from exploitation.

What is the impact? #

Upon successful exploitation, this vulnerability (tracked as CVE-2023-22515) can provide privilege escalation to external attackers allowing them to exploit the system and create Confluence administrator accounts, allowing for unrestricted access to affected instances.

Are updates available? #

Atlassian has made fixes available and strongly encourages admins to update their hosted instances. If patching in the near term isn’t viable, mitigation strategies to limit exploitation opportunities in addition to recommended steps to check for evidence of compromise are also provided. CISA has added this zero-day to its Known Exploited Vulnerabilities Catalog, advising organizations to check for evidence of compromise and reporting any positive findings back to CISA.

How do I find potentially vulnerable Confluence instances with runZero? #

From the Service Inventory, use the following pre-built query to locate assets running Confluence within your network which may need remediation or mitigation:

product:confluence OR (_asset.protocol:http AND protocol:http AND has:http.head.xConfluenceRequestTime)

As always, any prebuilt queries we create are available from our Queries Library. Check out the library for other useful inventory queries.
