4DescriptionCVE.org
Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in FF-RFI079I4 and FF-RFI078I4. A user who can log in to the product's M-Plane (NETCONF) may execute arbitrary OS commands.
AnalysisAI
OS command injection in the Lite-On FlexFi 5G radio products FF-RFI079I4 and FF-RFI078I4 allows anyone who can authenticate to the device's M-Plane (NETCONF) management interface to run arbitrary operating-system commands with the privileges of the management service, leading to full compromise of the radio unit. Affected firmware is version 02.01.15 and earlier; Lite-On has released a fix. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires (1) network reachability to the product's M-Plane/NETCONF management service - typically NETCONF-over-SSH on TCP/830, exposed on a management interface or management VLAN - and (2) a valid account that can log in to the M-Plane, matching the CVSS 4.0 PR:L rating; no user interaction (UI:N) and no special attack complexity (AC:L/AT:N) are required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H, score 8.7) describes a network-reachable, low-complexity flaw that requires only low privileges and no user interaction, with high confidentiality, integrity and availability impact on the device itself, but no subsequent-system (scope) impact. … 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 | Vendor-released patch: upgrade FF-RFI079I4 and FF-RFI078I4 to firmware 02.01.15 or later, as indicated by the vendor advisory at https://5g.liteon.com/security/flexfi/ and the JVN advisory at https://jvn.jp/en/jp/JVN02049764/. … Detailed patch versions, workarounds, and compensating controls in full report. |
