RHEL 9 : net-snmp (Unpatched Vulnerability)

medium Nessus Plugin ID 199959

Synopsis

The remote Red Hat 9 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- net-snmp: A buffer overflow in the handling of the INDEX of NET-SNMP-VACM-MIB can cause an out-of-bounds memory access. (CVE-2022-24805)

- net-snmp: A malformed OID in a SET to the nsVacmAccessTable can cause a NULL pointer dereference.
(CVE-2022-24810)

- 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. (CVE-2022-24806)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
