An issue was discovered in luci-app-https-dns-proxy on OpenWrt PR #15 (< 2026-01-17). The setInitAction function in /usr/libexec/rpcd/luci.https-dns-proxy allows authenticated users to execute arbitrary shell commands via shell metacharacters in the name parameter
AnalysisAI
Command injection in luci-app-https-dns-proxy on OpenWrt allows authenticated web-interface users to execute arbitrary shell commands on the router as the rpcd service account (typically root) by supplying shell metacharacters in the name parameter to the setInitAction RPC endpoint. The vulnerability exists in versions preceding the 2026-01-17 PR #15 fix across both the stangri and mossdef-org forks. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on the OpenWrt LuCI web interface with at minimum low-privilege (PR:L) access - an attacker must possess valid router credentials. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) is internally consistent: the attack is low-complexity and network-reachable via the LuCI web interface, but requires a valid authenticated session (PR:L), which meaningfully limits the exposed attack surface to users with LuCI credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update luci-app-https-dns-proxy to a build incorporating PR #15 from the upstream repository (https://github.com/stangri/luci-app-https-dns-proxy/pull/15 or the mossdef-org equivalent). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all OpenWrt systems running luci-app-https-dns-proxy and restrict web-interface access via firewall rules or disable remote administration. …
