EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 2.6%, top 16% of all CVEs by exploit prediction. 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 vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

InHand Networks IR615 Router's Versions 2.3.0.r4724 and 2.3.0.r4870 do not have a filter or signature check to detect or prevent an upload of malicious files to the server, which may allow an attacker, acting as an administrator, to upload malicious files. This could result in cross-site scripting, deletion of system files, and remote code execution.
