CVE-2022-24806: net-snmp vulnerable to Improper Input Validation when SETing malformed OIDs in master agent and subagent simultaneously
From https://github.com/net-snmp/net-snmp/blob/v5.9.2/CHANGES CVE-2022-24806 Improper Input Validation when SETing malformed OIDs in master agent and subagent simultaneously
Other sources
net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a user with read-write credentials can exploit an Improper Input Validation vulnerability when SETing malformed OIDs in master agent and subagent simultaneously. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.
