Published: 30 January 2026
Summary
CVE-2026-1687 is a medium-severity Injection (CWE-74) vulnerability in Tenda Hg10 Firmware. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 10.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
A weakness has been identified in the Tenda HG10 device running firmware US_HG7_HG9_HG10re_300001138_en_xpon. The issue resides in an unknown function of the /boaform/formSamba file within the Boa Webserver component. Remote manipulation of the serverString argument can trigger command injection, as classified under CWE-74 and CWE-77. The vulnerability carries a CVSS 4.0 score of 6.9 and is exploitable over the network without authentication.
An attacker can send a crafted HTTP request to the web interface from a remote position to execute arbitrary commands on the affected device. Public proof-of-concept code demonstrating the injection has been released, enabling straightforward reproduction of the attack.
No vendor advisory or patch information is referenced in the available sources. The associated EPSS score remains low, with a current value of 0.0561 and a peak of 0.0622, indicating limited observed exploitation interest to date.
