CVE-2017-6742
In short
A buffer overflow in SNMP allows an authenticated attacker to crash the system or run malicious code by sending a specially crafted SNMP message. This is serious because it gives attackers complete control over the affected device.
Technical detail
Buffer overflow vulnerability in SNMP implementation (versions 1, 2c, 3) exploitable by authenticated remote attackers via crafted SNMP packets directed to the affected system. Requires knowledge of SNMP community string (v2c/earlier) or SNMPv3 credentials; successful exploitation enables arbitrary code execution and full system compromise or denial of service via system reload.
Summary generated and translated by AI from the official description.
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.
