🚨 Critical CVEs Today: Totolink CGI Handler Risks (CVSS 9.8-9.8) Affected: Totolink A7100RU; CF Image Hosting Script Internet-facing exposure dominates as remote CGI vulnerabilities enable command execution and data exposure. • CVE-2026-6112 (CVSS 9.8) Totolink A7100RU 7.4cu.2313_b20191024; CGI Handler setRadvdCfg allows manipulation of maxRtrAdvInterval to enable OS command injection; remote exploitation possible. • CVE-2026-6113 (CVSS 9.8) Totolink A7100RU 7.4cu.2313_b20191024; CGI Handler setTtyServiceCfg enables manipulation of ttyEnable causing OS command injection; remote exploitation possible. • CVE-2026-6114 (CVSS 9.8) Totolink A7100RU 7.4cu.2313_b20191024; CGI Handler setNetworkCfg manipulation of proto leads to OS command injection; remote exploitation possible. • CVE-2019-25709 (CVSS 9.8) CF Image Hosting Script 1.6.5; Unauthenticated attackers can download and decode the application database by accessing imgdb.db in upload/data, exposing delete IDs that enable mass deletion of pictures. Action • Patch/upgrade to the fixed versions called out (or vendor advisory latest) • Prioritize internet-facing instances and edge appliances first • If "no fix yet", apply the stated mitigations and reduce exposure (disable feature/module, restrict access) • Add detections for the exploitation patterns implied by the CVEs (process spawning, webshell/file-write paths, auth anomalies) • Hunt for indicators around the affected services during the disclosure-to-now window (logs, EDR, WAF) • Validate remediation (version checks, config verification) and monitor for reversion
Post summary
The post announces several high‑CVSS Totolink and CF Image Hosting Script vulnerabilities, outlines technical details and remediation steps, but does not mention active exploitation or a proof of concept.
