6.8
Medium
| Vector | AV:N/AC:L/Au:S/C:N/I:C/A:N |
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 function. A user with read-only credentials can exploit this by using a malformed OID in a GET-NEXT request to cause the dereference. This can potentially impact data integrity. Users should use strong SNMPv3 credentials, avoid sharing credentials, and consider restricting access to a given IP address range for added protection.Recommendations
For versions prior to 5.9.2, update to version 5.9.2 or later to apply the patch.
Use strong SNMPv3 credentials and avoid sharing them.
For those who must use SNMPv1 or SNMPv2c, use a complex community string and restrict access to a given IP address range.
