EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under NVD CVSS v3. EPSS exploit probability: 1.2% (65th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A vulnerability in the management REST API of Cisco Industrial Network Director (IND) could allow an authenticated, remote attacker to cause the CPU utilization to increase to 100 percent, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of requests sent to the REST API. An attacker could exploit this vulnerability by sending a crafted request to the REST API. A successful exploit could allow the attacker to cause a permanent DoS condition that is due to high CPU utilization. Manual intervention may be required to recover the Cisco IND.
