Vulnerability Title
free5GC: NRF nnrf-nfm lacks NF Profile input validation — enables NF Registration Poisoning with arbitrary service endpoints
Vulnerability Description
free5GC is an open-source implementation of the 5G core network. In 4.2.2 and earlier, the NRF RegisterNFInstance handler at PUT /nnrf-nfm/v1/nf-instances/{nfInstanceID} accepts NF Profiles without enforcing UUID format, nfStatus enum values, heartBeatTimer ranges, mandatory profile fields, or nfServices.ipEndPoints address constraints. The invalid profiles are persisted in the MongoDB NfProfile collection and returned by NFDiscover, allowing an attacker with SBI access to advertise attacker-controlled network-function endpoints and redirect control-plane signaling. This can expose credentials and signaling, alter service discovery integrity, and deny service across network functions that trust the NRF. This issue is fixed in version 4.2.3.

输入验证不恰当
Vulnerability Title
free5GC 输入验证错误漏洞
Vulnerability Description
free5GC是free5GC团队开源的一个第 5 代 (5G) 移动核心网络的项目平台。 free5GC 4.2.2及之前版本存在输入验证错误漏洞,该漏洞源于NRF的RegisterNFInstance处理程序接受NF配置文件时未对UUID格式、nfStatus枚举值、heartBeatTimer范围、必填字段及nfServices.ipEndPoints地址约束进行有效验证,可能导致具有SBI访问权限的攻击者发布攻击者控制的网络功能端点并重定向控制平面信令,从而造成凭据和信令泄露、服务发现完整性被破坏
