Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Cacti是Cacti团队的一套开源的网络流量监测和分析工具。该工具通过snmpget来获取数据，使用RRDtool绘画图形进行分析，并提供数据和用户管理功能。 Cacti 存在操作系统命令注入漏洞，该漏洞源于lib/snmp.php文件中的一组函数，这些函数接受一些变量作为输入，然后将它们放入exec调用中，但没有进行适当的转义或验证。

Vulnerability Title
Authenticated command injection in SNMP options of a Device
Source: CVE Program / CVE List V5
Vulnerability Description
Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, under certain conditions, an authenticated privileged user, can use a malicious string in the SNMP options of a Device, performing command injection and obtaining remote code execution on the underlying server. The `lib/snmp.php` file has a set of functions, with similar behavior, that accept in input some variables and place them into an `exec` call without a proper escape or validation. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.
