Denial of service in the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets an unauthenticated remote attacker crash the RTSP service by sending a crafted second SETUP request after a valid RTSP handshake, knocking the camera offline for every client on the network. The flaw is a stack-based buffer overflow (CWE-121) in the RTSP second-stage URL routing parser; publicly available exploit code exists via a GitHub write-up, though no active exploitation is confirmed and the CVSS availability-only impact means it is a crash, not code execution, at time of analysis.

Denial of service in the RTSP service of Tenda CP3 V3.0 IP cameras (firmware V31.1.9.91) allows an unauthenticated remote attacker on the local network to crash the streaming service with a single crafted SETUP request. Because the second-stage URL routing parser does not validate the URL field length, a request whose URL is exactly four repetitions of a valid RTSP URL overflows a stack buffer and terminates the RTSP process, cutting off all clients. Publicly available exploit code exists (researcher write-up on GitHub); this is not listed in CISA KEV and no active exploitation is confirmed.

Denial of service in the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets an unauthenticated remote attacker crash the onboard RTSP service by sending a PLAY request whose Range header carries an over-long clock= value, triggering a stack-based buffer overflow (CWE-121). The flaw affects only availability - a successful attack knocks the camera's video streaming offline until it recovers or is restarted, with no confirmed path to code execution or data disclosure. There is a public research write-up on GitHub, but no active exploitation is recorded in CISA KEV and EPSS rates exploitation likelihood as low (0.19%, 9th percentile).

Denial of service in the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets an unauthenticated remote attacker exhaust TCP connection resources by sending RTSP requests (DESCRIBE, SETUP, PLAY) that advertise a Content-Length header but omit the message body, wedging the RTSP parser into a permanent body-awaiting state and leaking the connection. Repeated requests permanently disable the camera's streaming service. SSVC records a public proof-of-concept and rates the attack automatable; publicly available exploit code exists (POC), though it is not listed in CISA KEV, so there is no confirmation of active exploitation.

A public technical report with reproduction details exists on GitHub; the issue is not listed in CISA KEV and no EPSS score was provided.

Denial-of-service in the RTSP service of the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets remote unauthenticated attackers abruptly reset the streaming TCP connection by sending an RTSP request with an oversized field value. Rather than replying with an RFC 2326-compliant error, the service tears the connection down with a RST packet, indicating unsafe input handling in the RTSP parser that can disrupt video streaming. A public research report documenting the flaw exists on GitHub, but there is no CISA KEV listing and no confirmed active exploitation.

The CVSS 4.0 score of 7.4 reflects high confidentiality, integrity, and availability impact bounded by a low-privilege requirement.

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.

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.

Weak password requirements in the Samba service of Tenda AC15 firmware 15.03.05.19 expose SMB file-sharing functionality to brute-force attacks from adjacent-network attackers. The flaw originates in the /etc_ro/smb.conf configuration, which enforces insufficient password complexity, enabling unauthenticated local-network adversaries to guess or brute-force credentials and achieve limited confidentiality, integrity, and availability impact. Publicly available exploit code exists, though the high attack complexity (AC:H) and adjacency requirement (AV:A) constrain realistic exploitation to targeted, in-person or LAN-positioned threat actors.

Denial of service in Tenda AC1206 routers (firmware v15.03.06.23) is triggered by stack-based buffer overflows in the fromGstDhcpSetSer function reachable through the username and password parameters of a crafted HTTP request. Remote attackers with network reach to the device's web management interface can crash the service without authentication, and no public exploit identified at time of analysis although proof-of-concept research material is hosted on GitHub.

Denial of service in Tenda FH451 router firmware V1.0.0.9 allows remote unauthenticated attackers to crash the device by sending a crafted HTTP request that triggers a stack overflow in the list1 parameter of the fromDhcpListClient function.

Publicly available exploit code exists, and the CVSS 4.0 base score of 7.4 reflects high impact to confidentiality, integrity, and availability with low-privilege network access. No CISA KEV listing or EPSS score is provided, so widespread opportunistic exploitation is not confirmed at this time.

Stack-based buffer overflow in Tenda W12 firmware 3.0.0.7(4763) allows remote authenticated attackers to corrupt memory in the embedded HTTP daemon by supplying an oversized wifiMacFilterSet.macList.mac parameter to the cgiWifiMacFilterSet handler in /bin/httpd.
