Title

部分厂商设备SNMP协议社区字符串认证权限绕过漏洞

Description

SNMP是基于TCP/IP协议族的网络管理标准，是一种在IP网络中管理网络节点（如服务器、工作站、路由器、交换机等）的标准协议。部分厂商设备SNMP协议社区字符串存在认证权限绕过漏洞，由于不正确的访问控制，攻击者可以使用任意字符串或整数来完成某些特定设备中SNMP代理所要求的身份验证，甚至可以获取到目标设备完整的远程读写（read/write）权限。

CVE-2017-5135 (GCVE-0-2017-5135)

Vulnerability from cvelistv5 – Published: 2017-04-27 15:00 – Updated: 2024-08-05 14:55

Summary

Certain Technicolor devices have an SNMP access-control bypass, possibly involving an ISP customization in some cases. The Technicolor (formerly Cisco) DPC3928SL with firmware D3928SL-P15-13-A386-c3420r55105-160127a could be reached by any SNMP community string from the Internet; also, you can write in the MIB because it provides write properties, aka Stringbleed. NOTE: the string-bleed/StringBleed-CVE-2017-5135 GitHub repository is not a valid reference as of 2017-04-27; it contains Trojan horse code purported to exploit this vulnerability.
