CVE-2023-32315: Openfire vulnerability (update)

A few months ago, we published details about an important security vulnerability in Openfire that is identified as CVE-2023-32315.

To summarize: Openfire’s administrative console (the Admin Console), a web-based application, was found to be vulnerable to a path traversal attack via the setup environment. This permitted an unauthenticated user to access restricted pages in the Openfire Admin Console reserved for administrative users.

Leveraging this, a malicious actor can gain access to all of Openfire, and, by extension (through installing custom plugins), much of the infrastructure that is used to run Openfire. The Ignite Realtime community has made available new Openfire releases in which the issue is addressed, and published various mitigation strategies for those who cannot immediately apply an update. Details can be found in the security advisory that we released back in May.

In the last few days, this issue has seen a considerable increase in exposure: there have been numerous articles and podcasts that discuss the vulnerability. Many of these seem to refer back to a recent blogpost by Jacob Banes at, and those that do not seem to include very similar content.

Many of these articles point out that there’s a “new way” to exploit the vulnerability. We indeed see that there are various methods being used, in the wild, in which this vulnerability is abused. Some of these methods leave less traces than others, but the level of access that can be obtained through each of these methods is pretty similar (and, sadly, similarly severe).

Given the renewed attention, we’d like to make clear that there is no new vulnerability in Openfire. The issue, solutions and mitigations that are documented in the original security advisory are still accurate and up to date.

Malicous actors use a significant amount of automation. By now, it’s almost safe to assume that your instance has been compromised if you’re running an unpatched instance of Openfire that has its administrative console exposed to the unrestricted internet. Tell-tale signs are high CPU loads (of crypto-miners being installed) and the appearance of new plugins (which carry the malicious code), but this by no means is true for every system that’s compromised.

We continue to urge everyone to update Openfire to its last release, and carefully review the security advisory that we released back in May, to apply applicable mitigations where possible.
