一、漏洞信息
漏洞编号:CVE-2022-41741
漏洞归属组件:nginx
漏洞归属的版本:1.16.1,1.18.0,1.19.1,1.21.5,1.23.2
CVSS V3.0分值:
BaseScore:7.8 High
Vector:CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述:
NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to corrupt NGINX worker memory, resulting in its termination or potential other impact using a specially crafted audio or video file. The issue affects only NGINX products that are built with the ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_mp4_module.

二、漏洞分析结构反馈
影响性分析说明:
NGINX在模块ngx_http_mp4_module中存在漏洞,可能允许本地攻击者破坏NGINX worker内存,使用特制的音频或视频文件导致其终止或潜在的其他影响。当nginx构建的时候启用ngx_http_mp4_module,并在配置文件中使用 mp4指令时,攻击者可以利用此模块的漏洞用特制音频或视频文件进行攻击。
