A resource exhaustion flaw exists in the network processing loop of OpENer 2.3.0, leading to a denial of service when the server runs out of usable resources. The vulnerability is identified as CWE‑400, where an uncontrolled consumption of system resources permits a remote attacker to disrupt service availability, though the statement about a remote attacker is inferred from the typical nature of denial of service attacks.

The affected product is OpENer 2.3.0 (based on commit 76b95cf). No other vendors, products, or version ranges are listed in the CNA data.

The CVSS score of 7.5 signals a high impact, while the EPSS score of less than 1 % indicates a very low likelihood of exploitation at present. The vulnerability is not listed in the CISA KEV catalog, suggesting no publicly known exploits. Based on the description, the likely attack vector involves a host sending excessive traffic to the network processing loop to deplete resources; this inference is drawn from the noted resource exhaustion in the network loop.
