漏洞描述
中文描述:

Coturn是Coturn开源的一款TURN（VoIP媒体业务NAT穿越服务器和网关）和STUN（用户数据报协议简单穿越网络地址转换器）Server的开源实现。 Coturn 4.6.2r5版本至4.7.0-r4版本存在安全特征问题漏洞，该漏洞源于随机数生成器不安全，可能导致身份验证绕过和端口预测。

英文描述:

coturn is a free open source implementation of TURN and STUN Server. Versions 4.6.2r5 through 4.7.0-r4 have a bad random number generator for nonces and port randomization after refactoring. Additionally, random numbers aren't generated with openssl's RAND_bytes but libc's random() (if it's not running on Windows). When fetching about 50 sequential nonces (i.e., through sending 50 unauthenticated allocations requests) it is possible to completely reconstruct the current state of the random number generator, thereby predicting the next nonce. This allows authentication while spoofing IPs. An attacker can send authenticated messages without ever receiving the responses, including the nonce (requires knowledge of the credentials, which is e.g., often the case in IoT settings). Since the port randomization is deterministic given the pseudorandom seed, an attacker can exactly reconstruct the ports and, hence predict the randomization of the ports. If an attacker allocates a relay port, they know the current port, and they are able to predict the next relay port (at least if it is not used before). Commit 11fc465f4bba70bb0ad8aae17d6c4a63a29917d9 contains a fix.
