SCA: security update for org.igniterealtime.openfire:xmppserver (GHSA-w252-645g-87mp)

medium Tenable Cloud Security Plugin ID 435333

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Openfire is an XMPP server licensed under the Open Source Apache License. Openfire’s SASL EXTERNAL
 mechanism for client TLS authentication contains a vulnerability in how it extracts user identities from
 X.509 certificates. Instead of parsing the structured ASN.1 data, the code calls
 X509Certificate.getSubjectDN().getName() and applies a regex to look for CN=. This method produces a
 provider-dependent string that does not escape special characters. In SunJSSE
 (sun.security.x509.X500Name), for example, commas and equals signs inside attribute values are not
 escaped. As a result, a malicious certificate can embed CN= inside another attribute value (e.g.
 OU="CN=admin,"). The regex will incorrectly interpret this as a legitimate Common Name and extract admin.
 If SASL EXTERNAL is enabled and configured to map CNs to user accounts, this allows the attacker to
 impersonate another user. The fix is included in Openfire 5.0.2 and 5.1.0. (CVE-2025-59154)
