Russia's war upon Ukraine has continued for nearly two years, with terrible human and economic consequences.  Thus far, a Russian veto in the UN Security Council has blocked that international entity from imposing a settlement of the war.  But the UN Charter states that a party to a dispute before the Security Council shall abstain from voting on it.  And, in fact, such abstention was practiced for years within the Security Council.  Therefore, both international law and precedent point toward the United Nations taking action to establish a just peace in Ukraine.
