CVE-2026-11553 Jun 08, 17:15 HIGH POC This Week

Stack-based buffer overflow in Tenda HG7, HG9, and HG10 XPON ONT routers (firmware 300001138_en_xpon) allows authenticated remote attackers to corrupt memory via the encodename parameter of the formPPPEdit handler at /boaform/formPPPEdit. Publicly available exploit code exists (hosted on GitHub by researcher xiezhihua-1127), elevating practical risk despite no confirmed active exploitation in CISA KEV. Successful exploitation yields high impact to confidentiality, integrity, and availability on the affected device.

CVE-2026-11499 Jun 08, 07:00 CRITICAL Act Now

Stack-based buffer overflow in Tenda HG7HG9 and HG10 routers (firmware 300001138_en_xpon) allows remote attackers to corrupt memory via the blkDomain parameter in the formDOMAINBLK handler at /boaform/formDOMAINBLK. The CVSS 4.0 score of 9.3 reflects network-reachable, unauthenticated exploitation with high impact to confidentiality, integrity, and availability, and a public proof-of-concept repository has been published on GitHub by researcher ssaaaa1234, though no public exploit has been confirmed as active exploitation.

CVE-2026-11498 Jun 08, 06:45 HIGH This Week

Stack-based buffer overflow in Tenda HG7, HG9, and HG10 ONT/router devices (firmware 300001138_en_xpon) allows authenticated remote attackers to corrupt memory by manipulating the funckey_transfer parameter sent to the /boaform/voip_other_set endpoint handled by the asp_voip_OtherSet function. Publicly available exploit code exists via a dedicated GitHub proof-of-concept repository, and the flaw scores CVSS 4.0 8.7 with full confidentiality, integrity, and availability impact. No public exploit identified in CISA KEV at time of analysis, but exposure of the Web Management Interface to untrusted networks materially raises real-world risk.
