1DescriptionCVE.org
A flaw has been found in LB-Link WR1210M 1.0.3. This impacts the function main of the file /www/cgi-bin/backup.cgi of the component Backup Endpoint. This manipulation causes missing authentication. The attack is only possible within the local network. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
The backup endpoint on LB-Link WR1210M firmware 1.0.3 exposes device configuration data to unauthenticated adjacent-network attackers due to missing authentication in the main() function of /www/cgi-bin/backup.cgi. Any attacker on the same local network segment can retrieve the router's backup archive without credentials, potentially obtaining Wi-Fi passphrases, administrative passwords, and network configuration. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same local network segment as the router - adjacency (AV:A) is a hard constraint, meaning internet-sourced attacks are not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 accurately reflects the constrained threat model: AV:A limits exploitation to adjacent-network attackers only, ruling out internet-based attacks entirely. … 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 vendor did not respond to responsible disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
