Remotely reachable admin-only endpoint so AV:N/AC:L/PR:H; command injection yields full device OS control (C/I/A:H) confined to the router itself, so S:U.

6DescriptionCVE.org
A vulnerability was found in Ruijie RG-EW3000GX EW_3.0(1)B11P380. Affected by this issue is some unknown functionality of the file /etc/rg_config/admin of the component user_list_note Module. Performing a manipulation of the argument Name results in os command injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used.
AnalysisAI
A high-privileged authenticated attacker can inject and execute arbitrary operating-system commands on the Ruijie RG-EW3000GX router running firmware EW_3.0(1)B11P380, through the user_list_note functionality that manipulates the Name argument resolved from /etc/rg_config/admin. The vulnerability is network-reachable and requires no user interaction, but the CVSS vector (PR:H) confirms it is only exploitable after obtaining administrator credentials for the device management interface, so anonymous internet attackers cannot reach it directly. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires authenticated administrative access to the RG-EW3000GX management interface (CVSS PR:H) - the vulnerable user_list_note functionality tied to /etc/rg_config/admin is an admin-only feature, so an anonymous attacker cannot reach it without first obtaining admin credentials. … 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:H/UI:N/VC:H/VI:H/VA:H) describes a remotely reachable OS command injection on the Ruijie RG-EW3000GX router that nonetheless requires high privileges (PR:H) - consistent with the affected file being /etc/rg_config/admin and the endpoint sitting inside an authenticated admin module. … 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 | No vendor-released patch has been identified at time of analysis - the available references (VulDB entry 405550 and its CTI/submit pages) contain no fixed firmware version, so administrators of RG-EW3000GX units on EW_3.0(1)B11P380 should assume the device is unpatched and monitor Ruijie's support portal for a corrective firmware release, then upgrade immediately once one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Ruijie RG-EW3000GX devices running firmware EW_3.0(1)B11P380, immediately disable WAN management access and restrict the management interface to trusted internal networks only, enforce strong unique administrator passwords, and enable logging to detect anomalous user_list_note activity. …
