Tenda AC10 Multiple Buffer Overflow Vulnerabilities

Stack-based buffer overflow in Tenda AC10 router firmware version 16.03.10.10_multi_TDE01 allows authenticated remote attackers to achieve complete system compromise through the fromSysToolChangePwd function in /bin/httpd. The vulnerability requires only low-privilege authentication (CVSS PR:L) and has low attack complexity, enabling potential remote code execution with full confidentiality, integrity, and availability impact. No public exploit code identified at time of analysis, though detailed technical findings have been published on GitHub documenting multiple vulnerable endpoints.

Stack-based buffer overflow in Tenda AC10 router firmware 16.03.10.10_multi_TDE01 allows authenticated remote attackers to achieve code execution with high impact to confidentiality, integrity, and availability. The vulnerability resides in the fromSysToolChangePwd function within /bin/httpd, triggered by manipulating the sys.userpass parameter. Publicly available exploit code exists (GitHub repository documented), though no confirmed active exploitation (not in CISA KEV). CVSS 8.8 reflects network-accessible attack requiring only low-privilege authentication with low complexity, making this a realistic threat for internet-exposed routers with default or compromised credentials.

Stack-based buffer overflow in UTT HiPER 1250GW router (versions up to 3.2.7-210907-180535) allows authenticated remote attackers to achieve arbitrary code execution with high integrity and availability impact via malformed Profile parameter in /goform/formRemoteControl endpoint. Publicly available exploit code exists. CVSS 8.8 reflects network accessibility with low attack complexity, though authentication requirement (PR:L) moderately reduces immediate exploit surface. No CISA KEV listing indicates exploitation remains proof-of-concept stage rather than widespread campaign activity.
