CVE-2026-19900: Hard-coded Credentials in LB-LINK X-PRO
A vulnerability was identified in LB-LINK X-PRO 1.0.22-20231206. The impacted element is an unknown function of the file /etc/shadow. The manipulation leads to hard-coded credentials. It is possible to initiate the attack remotely. A high degree of complexity is needed for the attack. The exploitability is regarded as difficult. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
This vulnerability in LB-LINK X-PRO 1.0.22-20231206 involves hard-coded credentials linked to an unknown function interacting with the /etc/shadow file. The flaw allows remote attackers to potentially gain unauthorized access, but exploitation is difficult due to the complexity involved. The CVSS 4.0 score is 9.2 (critical), reflecting network attack vector, high complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No vendor response or patch is available, and the exploit is publicly accessible.
Potential Impact
Successful exploitation could allow remote attackers to bypass authentication or gain unauthorized access due to hard-coded credentials, potentially compromising system confidentiality, integrity, and availability. The high CVSS score indicates severe impact if exploited.
Mitigation Recommendations
No official patch or remediation is currently available, and the vendor has not responded to disclosure. Users should monitor vendor communications for updates. Until a fix is provided, consider restricting network access to the affected device and employing compensating controls to limit exposure.
