NewCVE-2025-53399 (opens in a new tab)How to fix?
Upgrade sipwise/rtpengine to version 13.4.1.1 or higher.
Overview
Affected versions of this package are vulnerable to Origin Validation Error via improper origin validation in the endpoint-learning process. An attacker can inject or intercept RTP/SRTP media streams by sending crafted RTP packets.
Note:
This is only exploitable if the relay is not configured for strict source and learning is not disabled.
Workaround
This vulnerability can be mitigated by enabling strict source configuration and disabling endpoint learning. When using SDES-SRTP, it is recommended to use both strict source and recrypt flags for complete protection.
