• → Monitor for POST requests to /qcenter/hawkeye/v1/date_config with a base64-encoded 'passwd' field; the passwd value decodes to a shell injection payload (e.g., contains semicolons and shell commands). ↗
• → Alert on GET requests to /qcenter/hawkeye/v1/account by non-admin roles (e.g., ROLE=1082130432 viewer), which may indicate privilege escalation reconnaissance to harvest the admin base64 password. ↗
• → Detect unexpected file creation under /tmp/ (e.g., /tmp/date_config, /tmp/netconfigpower) on QNAP Q'center appliances, which are artifacts of successful command injection via the passwd parameter. ↗
• → Flag HTTP responses from /qcenter/hawkeye/v1/account that include the 'new_password' field in JSON output, as this leaks the admin password encoded in base64. ↗
• → Inspect POST bodies to /qcenter/hawkeye/v1/date_config for the 'passwd' key containing base64 strings that decode to shell metacharacters (e.g., semicolons, quotes, touch/echo commands). ↗

• · The command injection in CVE-2018-0709 requires an authenticated session; exploitation is facilitated by first chaining with CVE-2018-0706 (password disclosure) to obtain admin credentials. ↗
• · A Power User role (ROLE=1610612735) can also trigger the date_config injection endpoint despite the web UI not exposing this function to that role, broadening the attacker surface beyond admin-only. ↗
• · The passwd field is base64-encoded before submission, meaning shell metacharacters pass through any surface-level input filters undetected until decoded server-side. ↗
• · Affected versions confirmed in testing are Q'center Virtual Appliance 1.6.1056 (20170825) and 1.6.1075 (20171123); NVD lists 1.7.1063 and earlier as vulnerable. ↗
