CVE-2026-31255: n/a
A command injection vulnerability exists in Tenda AC18 V15.03.05.05_multi. The vulnerability is located in the /goform/SetSambaCfg interface, where improper handling of the guestuser parameter allows attackers to execute arbitrary system commands.
AI Analysis
Technical Summary
This vulnerability involves a command injection flaw in the Tenda AC18 router firmware (V15.03.05.05_multi) specifically in the /goform/SetSambaCfg interface. The issue arises from improper sanitization or validation of the guestuser parameter, which can be manipulated by an attacker to execute arbitrary system commands on the device. The CVE is published but lacks CVSS scoring and detailed vendor remediation information.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary system commands on the affected router, potentially leading to full control over the device. This could compromise the confidentiality, integrity, and availability of the router and connected network. However, no known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider limiting access to the affected interface and monitor for updates from Tenda regarding patches or mitigations.
