| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
net-snmp versions prior to 5.9.2
Description
The issue is related to a NULL pointer dereference in the nsVacmAccessTable component of the net-snmp software. This can be caused by a user with read-write credentials using a malformed OID in a SET to the nsVacmAccessTable. To protect against this, users should use strong SNMPv3 credentials and avoid sharing them. For those who must use SNMPv1 or SNMPv2c, using a complex community string and restricting access to a given IP address range can enhance protection.
Recommendations
For versions prior to 5.9.2, update to version 5.9.2 or later to apply the patch.
As a temporary workaround, consider restricting access to the nsVacmAccessTable component until the patch is applied.
Use strong SNMPv3 credentials and avoid sharing them.
For SNMPv1 or SNMPv2c, use a complex community string and restrict access to a given IP address range.
