EUVDB-ID: #VU2215
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-5621
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to the snmp_pdu_parse function in snmp_api.c does not remove the varBind variable in a netsnmp_variable_list item when parsing of the SNMP PDU fails. A remote attacker can supply specially crafted input and cause denial of service or execute arbitrary code with elevated privileges.
