5DescriptionCVE.org
A vulnerability was determined in EFM ipTIME C200E 1.094. The impacted element is an unknown function of the file iux_set.cgi of the component System Setup. This manipulation causes os command injection. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.
AnalysisAI
OS command injection in EFM ipTIME C200E firmware 1.094 allows an authenticated remote attacker with administrative privileges to execute arbitrary operating system commands via a crafted request to the iux_set.cgi endpoint in the System Setup component. A public proof-of-concept exploit, including a video demonstration, has been disclosed. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) administrative (PR:H) authentication to the device's web management interface - the vulnerability resides in the System Setup component (iux_set.cgi), which is gated behind admin login; (2) network reachability to the device's HTTP/HTTPS management port (AV:N). … 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 yielding 8.5 correctly reflects the key mitigating factor: PR:H (high privileges required), meaning an attacker must already possess administrative credentials to the device's web interface. … 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, create a complete inventory of all EFM ipTIME C200E devices running firmware 1.094 and immediately restrict administrative access by disabling unnecessary admin accounts and reviewing all current administrative credentials. …
