Openfire is an XMPP server licensed under the Open Source Apache License. Openfire's administrative 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 use the unauthenticated Openfire Setup Environment in an already configured Openfire environment to access restricted pages in the Openfire Admin Console reserved for administrative users. This vulnerability affects all versions of Openfire that have been released since April 2015, starting with version 3.10.0. The problem has been patched in Openfire release 4.7.5 and 4.6.8, and further improvements will be included in the yet-to-be released first version on the 4.8 branch (which is expected to be version 4.8.0). Users are advised to upgrade. If an Openfire upgrade isn’t available for a specific release, or isn’t quickly actionable, users may see the linked github advisory (GHSA-gw42-f939-fhvm) for mitigation advice.

Vendor statements

Quoted
CloudflareWAF Managed RulesBefore feed history

The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.

AWSAWS WAF Managed RulesNo public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. AWS often describes a vulnerability without naming its CVE (for example "Log4j"). We count only entries that name the CVE, so AWS coverage is understated.

Microsoft AzureFront Door and Application Gateway WAF (DRS)No public claim

We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. The rule tables name CVEs but carry no dates, so Azure is left out of every time-to-rule figure.
