CVE-2023-29453— Zabbix 代码注入漏洞

Agent 2 package are built with Go version affected by CVE-2023-24538

Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them as expected. Backticks are used, since ES6, for JS template literals. If a template contains a Go template action within a Javascript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary Javascript code into the Go template. As ES6 template literals are rather complex, and themselves can do string interpolation, the decision was made to simply disallow Go template actions from being used inside of them (e.g., "var a = {{.}}"), since there is no obviously safe way to allow this behavior. This takes the same approach as github.com/google/safehtml. With fix, Template. Parse returns an Error when it encounters templates like this, with an ErrorCode of value 12. This ErrorCode is currently unexported but will be exported in the release of Go 1.21. Users who rely on the previous behavior can re-enable it using the GODEBUG flag jstmpllitinterp=1, with the caveat that backticks will now be escaped. This should be used with caution.

Zabbix 代码注入漏洞

Zabbix是Zabbix公司的一套开源的监控系统。该系统支持网络监控、服务器监控、云监控和应用监控等。 Zabbix plugin Agent 2 存在安全漏洞，该漏洞源于Agent 2 包是使用受 CVE-2023-24538 影响的 Go 版本构建的，模板没有正确地将反引号 (`) 视为 Javascript 字符串分隔符，也没有按预期转义它们。
