CVE-2026-2907

Status: AnalyzedHigh (7.4)—

A weakness has been identified in Tenda HG9 300001138. Affected by this vulnerability is an unknown functionality of the file /boaform/formgponConf of the component GPON Configuration Endpoint. This manipulation of the argument fmgpon_loid/fmgpon_loid_password causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques
