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
NET-SNMP-AGENT-MIB::nsLogTable function. A user with read-write credentials can use a malformed OID in a SET request to cause this issue. To mitigate the risk, 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
To resolve the issue, update to version 5.9.2 or later.
As a temporary workaround, consider restricting access to the
NET-SNMP-AGENT-MIB::nsLogTable function until a 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.Exploit
