CVE-2022-30698

一、漏洞信息
漏洞编号：CVE-2022-30698
漏洞归属组件：unbound
漏洞归属的版本：1.10.1,1.11.0,1.13.2
CVSS V3.0分值：
BaseScore：6.5 Medium
Vector：CVSS：3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
漏洞简述：
NLnet Labs Unbound, up to and including version 1.16.1 is vulnerable to a novel type of the ghost domain names attack. The vulnerability works by targeting an Unbound instance. Unbound is queried for a subdomain of a rogue domain name. The rogue nameserver returns delegation information for the subdomain that updates Unbound s delegation cache. This action can be repeated before expiry of the delegation information by querying Unbound for a second level subdomain which the rogue nameserver provides new delegation information. Since Unbound is a child-centric resolver, the ever-updating child delegation information can keep a rogue domain name resolvable long after revocation. From version 1.16.2 on, Unbound checks the validity of parent delegation records before using cached delegation information.

二、漏洞分析结构反馈
影响性分析说明：
1.16.2之前的Unbound被查询到了一个恶意域名的子域。恶意域名服务器返回该子域的委托信息，更新Unbound的委托缓存。这个动作可以在授权信息过期之前重复进行，即查询Unbound的二级子域，恶意名称服务器为其提供新的授权信息。由于Unbound是一个以子域为中心的解析器，不断更新的子域委托信息可以使恶意域名在撤销后长期保持可解析性
