A vulnerability in the SNMP implementation of could allow an authenticated, remote attacker to cause a reload of the affected system or to remotely execute code. An attacker could exploit this vulnerability by sending a crafted SNMP packet to the affected device.
The vulnerability is due to a buffer overflow in the affected code area. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3). The attacker must know the SNMP read only community string (SNMP version 2c or earlier) or the user credentials (SNMPv3). An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system.
Only traffic directed to the affected system can be used to exploit this vulnerability.

Detection & IOCsextracted from sources · hover to see the quote
- →Exploit vector is a crafted SNMP packet sent via IPv4 or IPv6 directly to the affected Cisco IOS/IOS XE device; only traffic directed to the affected system can be used to exploit this vulnerability ↗
- →All three SNMP versions (1, 2c, 3) are affected; monitor for anomalous SNMP traffic on UDP/161 and UDP/162 to Cisco IOS/IOS XE devices ↗
- →For SNMPv1/v2c exploitation, attacker must know the SNMP read-only community string; alert on SNMP requests using default or known community strings from untrusted sources ↗
- →For SNMPv3 exploitation, attacker must have valid user credentials; monitor for SNMPv3 authentication attempts from unexpected sources ↗
- →Successful exploitation results in arbitrary code execution or device reload; unexpected Cisco IOS/IOS XE reloads may indicate exploitation attempts ↗
- →Track Cisco bug IDs CSCsy56638, CSCve54313, and CSCve57697 for patch status on affected Cisco IOS and IOS XE devices ↗
- ·The vulnerability is a buffer overflow in the SNMP subsystem; applies to Cisco IOS and IOS XE Software across all SNMP versions (1, 2c, 3) ↗
- ·Customers are advised to apply the workaround (disabling or restricting SNMP access via ACLs) as described in the Cisco Security Advisory ↗

CVE-2017-6741 [HIGH] CWE-119 GHSA-4p2r-xxqf-p9x8: The Simple Network Management Protocol (SNMP) subsystem of Cisco IOS 12
The Simple Network Management Protocol (SNMP) subsystem of Cisco IOS 12.0 through 12.4 and 15.0 through 15.6 and IOS XE 2.2 through 3.17 contains multiple vulnerabilities that could allow an authenticated, remote attacker to remotely execute code on an affected system or cause an affected system to reload. An attacker could exploit these vulnerabilities by sending a crafted SNMP packet to an affected system via IPv4 or IPv6. Only traffic directed to an affected system can be used to exploit these vulnerabilities. The vulnerabilities are due to a buffer overflow condition in the SNMP subsystem of the affected software. The vulnerabilities affect all versions of SNMP: Versions 1, 2c, and 3. To exploit these vulnerabilities via SNMP Version 2c or earlier, the attacker must know the SNMP read-
