Summary

Micro Registration Utility (µURU) is a telephone self registration utility based on Asterisk. In versions up to and including commit 88db9a953f38a3026bcd6816d51c7f3b93c55893, an attacker can craft a special federation name and inject characters treated special by Asterisk into the Dial() application due to improper input validation. This allows redirecting calls on both federating instances. However, it requires that an admin accept the federation requests. As of publication, no known patched version is available.

Risk Assessment

An attacker could redirect phone calls, potentially leading to eavesdropping, fraud, or disruption of telephone services. However, this requires admin acceptance.

Recommendation

Monitor vendor updates and apply patches when available. Temporarily restrict acceptance of federation requests.
