The SNMP agent of Loytec LIP-ME201C, L-INX, L-GATE, L-ROC, L-IOB, L-DALI, L-VIS and L-PAD through 8.4.16 (LINX-A64) uses attacker-controlled input as a loop condition without validation (CWE-606). An unauthenticated remote attacker can cause a persistent denial of service through CPU exhaustion by sending a crafted SNMP GETNEXT request containing a large OID component.
