What to do
AI-suggested
1. Implement strict policies and training to ensure administrators carefully validate and authenticate all federation requests before approval. 2. Employ network segmentation to isolate µURU instances and limit lateral movement in case of compromise. 3. Monitor and log all federation requests and call routing changes to detect suspicious activity promptly. 4. Apply input validation controls at the application level to sanitize federation names and reject inputs containing special characters or injection patterns. 5. Use multi-factor authentication and least privilege principles for administrative accounts managing federation requests. 6. Engage with the vendor or community to track patch releases and apply updates immediately once available. 7. Consider deploying compensating controls such as call anomaly detection systems to identify unusual call redirection patterns. 8. Conduct regular security assessments and penetration testing focused on telephony infrastructure to identify similar weaknesses.
Description
Micro 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.
