CVE-2025-69205
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMicro Registration Utility (µURU) is a telephone self registration utility based on asterisk. In versions up to and including commit 88db9a953f38a3026bcd6816d51c7f3b93c55893, an attacker can crafts a special federation name and characters treated special by asterisk can be injected into the `Dial( )` application due to improper input validation. This allows an attacker to redirect calls on both of the federating instances. If the attack succeeds, the impact is very high. However, the requires that an admin accept the federation requests. As of time of publication, a known patched version of µURU is not available.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMicro Registration Utility (µURU) suffers from improper input validation when processing federation names. Attackers can inject special Asterisk characters into the Dial() application through crafted federation names, enabling call redirection on both federating instances. The attack requires an admin to accept a malicious federation request.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify µURU installationCheck if Micro Registration Utility is installed on the system by searching for executable files named 'uuru', 'uurud', or checking system services for µURU-related processesAffected if µURU is not installed then the system is not affected
-
Confirm federation feature is enabledInspect µURU configuration files or running configuration for federation settings, typically found in /etc/uuru/, /opt/uuru/conf/, or similar application config directoriesAffected if Federation is not enabled or configured, the attack surface does not exist
-
Inspect federation name entries for special charactersReview all federation peer configurations and examine federation name fields for the presence of Asterisk (*) characters or other shell metacharacters that could be interpreted by Dial()Affected if Any federation name contains unescaped Asterisk (*) or special characters used in Dial() context
-
Check Dial() application integrationExamine µURU logs and Dial() application call routing configuration to verify if federation names are passed directly to the Dial() function without sanitizationAffected if Federation names are passed directly to Dial() without input validation or escaping of special characters
A system is affected if µURU with federation enabled processes federation names containing unescaped Asterisk characters that get passed to the Dial() application without validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUntil a patch is available, strictly limit federation requests to trusted sources and implement input validation/sanitization on federation names to strip or escape Asterisk special characters before use in Dial().
