一、漏洞信息
漏洞编号：CVE-2024-39702
漏洞归属组件：openresty
漏洞归属的版本：1.19.3.1,1.21.4.1
CVSS V3.0分值：
BaseScore：5.9 Medium
Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
漏洞简述：
In lj_str_hash.c in OpenResty 1.19.3.1 through 1.25.3.1, the string hashing function (used during string interning) allows HashDoS (Hash Denial of Service) attacks. An attacker could cause excessive resource usage during proxy operations via crafted requests, potentially leading to a denial of service with relatively few incoming requests. This vulnerability only exists in the OpenResty fork in the openresty/luajit2 GitHub repository. The LuaJIT/LuaJIT repository. is unaffected.
