MITRE ATT&CK
1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires network access to the device's HTTP web-management interface and the ability to send a request to the /goform/formAccept endpoint with attacker-controlled input in the submit-url argument. Per the CVSS vector (PR:N/UI:N), no authentication or user interaction is needed. The principal limiting factor is exposure of the management interface: routers with their admin interface reachable only from the LAN are exploitable only by on-network or pivoted attackers, whereas WAN-exposed management dramatically widens reach. Because this is an end-of-life Edimax BR-6208AC (firmware 1.32) with no vendor patch, the only mitigations are network segmentation, disabling remote administration, or device replacement. |
| Impact | Moderate real-world priority. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) indicates a remotely reachable, low-complexity, unauthenticated command-injection flaw, which is the kind of signal that normally drives urgency. However, several factors temper this: the vendor-supplied 4.0 score of 6.9 (MEDIUM) reflects only LOW vulnerable-system impacts (VC:L/VI:L/VA:L), which is unusually conservative for a CWE-77 command-injection bug that typically yields full device compromise - this is a conflicting signal worth noting, as command injection on embedded routers usually warrants HIGH impact. The Exploit Maturity is E:P (Proof-of-Concept), and a public PoC exists on GitHub, but there is NO EPSS score, NO CISA KEV listing, and no SSVC decision data provided, so automatability and confirmed exploitation cannot be assessed from the input. Critically, this is an END-OF-LIFE product with no vendor response and no patch, meaning exposure is permanent for anyone still running it. The overall picture is a low-footprint, unpatchable device with a working PoC: dangerous where deployed but likely limited to targeted or opportunistic IoT-botnet scanning rather than broad enterprise impact. The only intelligence source is VulDB; no NVD or vendor corroboration is available. |
| Exploit ScenarioDerived | An attacker with network reach to the router's web management interface sends a crafted request to /goform/formAccept with a malicious payload in the submit-url argument, injecting shell commands that execute on the device. A public proof-of-concept is available on GitHub (fizz-is-on-the-way/Iot_vuls), lowering the barrier to exploitation. Because the attack is remote, unauthenticated (PR:N), and low-complexity, it could be automated by IoT botnets scanning for exposed management interfaces. |

Alert meAnalysisAIv1 – Oct 12, 2026
Unauthenticated remote command injection in the end-of-life Edimax BR-6208AC router (firmware 1.32) allows an attacker who can reach the device's HTTP web-management interface to execute arbitrary operating-system commands by manipulating the submit-url argument of the /goform/formAccept endpoint. The assessed CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H) confirms that no credentials and no user interaction are required, and publicly available exploit code exists in the GitHub repository referenced by the disclosure. Edimax was contacted before publication but did not respond and has shipped no patched firmware; the original CVSS 4.0 score of 6.9 understates the confidentiality, integrity and availability impact compared with the independent assessment, and overall exploitability is governed mainly by whether the management interface is reachable from the WAN or only from the local network, making this a moderate real-world priority.
RemediationAI
No vendor-released patch identified at time of analysis: Edimax was notified early but did not respond, the BR-6208AC is end-of-life and unsupported, and no fixed firmware version is available anywhere in the source data, so upgrading is not an option and replacement with a currently supported router is the only complete fix. Until the device can be retired, apply the following compensating controls with their trade-offs: block inbound WAN access to the router's web-management ports (typically TCP 80/443 or any custom admin port) at the upstream firewall or ISP router, accepting that remote administration becomes impossible; disable the device's remote-management/WAN-administration setting if present in the UI, understanding this is a hardening step and not proof of immunity against LAN-side exploitation; place the router on an isolated VLAN or guest network so that only trusted administrative hosts can reach /goform/formAccept, which limits lateral movement at the cost of extra switch/VLAN configuration; and restrict administrative access to a dedicated management subnet where the PoC path can never be reached from user or IoT segments. Detection should focus on POST requests to /goform/formAccept whose submit-url parameter contains shell metacharacters such as semicolons, backticks or pipes, since such traffic is anomalous for legitimate administration.

Technical ContextAI · show details
The root cause is CWE-77 (Improper Neutralization of Special Elements used in a Command), a classic OS command injection. The BR-6208AC runs an embedded Linux firmware image whose CGI-style web management interface exposes the /goform/ handler namespace; the formAccept handler takes an attacker-supplied submit-url parameter and passes it into a shell invocation without sanitization of shell metacharacters, so injected commands are executed with the privileges of the web server process (typically root or an equivalent privileged daemon on consumer router firmware). Because the vulnerable component is the HTTP management service rather than a feature behind authentication, the exposure surface is the web UI itself: any network path that lets a client POST to /goform/formAccept is sufficient. The CPE string cpe:2.3:a:edimax:br-6208ac:*:*:*:*:*:*:*:* with a wildcard version field and the absence of a fixed-version reference reflect that the vendor has discontinued the product line and no corrected firmware has been published, leaving no configuration-level fix inside the device.

Remote, low-complexity, unauthenticated command injection on an embedded router typically runs with full (root) privilege, so AV:N/AC:L/PR:N/UI:N and C/I/A:H; contrasts with the vendor's conservative LOW impacts.

2DescriptionCVE.org
A vulnerability was found in Edimax BR-6208AC 1.32. This vulnerability affects unknown code of the file /goform/formAccept. Performing a manipulation of the argument submit-url results in command injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
