CVE-2017-6737
CVE-2017-6737
In short
A buffer overflow in SNMP allows authenticated attackers to crash systems or run malicious code by sending specially crafted network packets. This is critical because SNMP is commonly used to monitor network devices, and successful exploitation could give attackers complete control.
Technical detail
A buffer overflow vulnerability in SNMP implementations (versions 1, 2c, and 3) allows authenticated remote attackers to execute arbitrary code or trigger system reloads via crafted SNMP packets. The attacker requires knowledge of SNMP read-only community strings or SNMPv3 credentials; exploitation is limited to direct network traffic to the affected device and results in arbitrary code execution with full system control.
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.
