CVE-2017-3881 – Cisco IOS and IOS XE Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2017-3881
A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: (1) the failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device; and (2) the incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. • https://www.exploit-db.com/exploits/41872 https://www.exploit-db.com/exploits/42122 https://github.com/homjxi0e/CVE-2017-3881-exploit-cisco- https://github.com/homjxi0e/CVE-2017-3881-Cisco https://github.com/1337g/CVE-2017-3881 https://github.com/mzakyz666/PoC-CVE-2017-3881 http://www.securityfocus.com/bid/96960 http://www.securityfocus.com/bid/97391 http://www.securitytracker.com/id/1038059 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-201 • CWE-20: Improper Input Validation •
