MITRE ATT&CK
1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation targets the Network Configuration Management component of the Tenda CP3 (firmware 27.5.57.101) and, per the CVSS 4.0 vector's PR:H, requires authenticated high-privilege (administrator) access to the camera's management interface reachable over the network; input reaching sub_2F77E8 in Apis/system.c must be attacker-controllable. Limiting factors: it is NOT unauthenticated - valid admin credentials are needed, so the practical risk concentrates on internet-exposed cameras with default or weak passwords; no user interaction is required (UI:N) and no non-default feature toggle is documented. |
| Impact | This is a genuinely high-impact bug (full device RCE) but several signals temper the raw 9.4 score. The CVSS 4.0 vector specifies PR:H, meaning valid high-level credentials to the management interface are required - this is not a pre-auth remote takeover, which substantially narrows the attacker population. The vector also asserts a scope change with high subsequent-system impact (SC:H/SI:H/SA:H); that is questionable for a self-contained camera and appears to inflate the score - command injection here compromises the vulnerable device itself, not a distinct downstream system, so I assess no scope change. There is no EPSS value, no CISA KEV listing, and no public PoC in the provided references; the sole source is VulDB, which auto-generates high CVSS 4.0 scores. Real-world priority is moderate: patch it, but the PR:H requirement and single-source/low-corroboration status argue against emergency treatment absent internet-exposed cameras with weak/default admin credentials. |
| Exploit ScenarioDerived | An attacker who has obtained admin credentials (or reaches an internet-exposed camera still using default/weak ones) sends a crafted network-configuration request to the management interface, embedding shell metacharacters in a parameter processed by sub_2F77E8. The injected command executes on the camera OS (typically as root), letting the attacker plant a backdoor, pivot into the surveillance network, or hijack the video feed. No public PoC is currently available. |

Alert meAnalysisAIv1 – Sep 06, 2026
OS command injection in the Tenda CP3 IP camera (firmware 27.5.57.101) lets an attacker inject shell commands through the function sub_2F77E8 in Apis/system.c, part of the Network Configuration Management component. Successful exploitation yields arbitrary command execution on the camera's embedded Linux OS. The CVSS 4.0 vector requires high privileges (PR:H), and no public exploit or active exploitation has been identified at time of analysis.
RemediationAI
No vendor-released patch identified at time of analysis; the references contain only VulDB entries and Tenda's homepage, not a fixed firmware version. As compensating controls: remove these cameras from direct internet exposure and place them on an isolated VLAN reachable only by the NVR/management host (trade-off: complicates remote viewing); restrict access to the web/management interface via firewall ACLs to trusted admin IPs; change default/weak administrator credentials since exploitation requires privileged access (PR:H), so strong unique passwords materially reduce risk; disable remote/cloud management and UPnP port-forwarding if enabled. Monitor Tenda (https://www.tenda.com.cn/) for a firmware update superseding 27.5.57.101 and apply it once published.

Technical ContextAI · show details
The Tenda CP3 is a consumer/SMB pan-tilt IP surveillance camera running an embedded Linux firmware. The flaw is a classic CWE-77 command injection: a handler (sub_2F77E8, an IDA-style function label from static analysis of the firmware binary) in system.c takes attacker-influenced input used in network configuration and passes it to a shell/system call without adequate sanitization, so shell metacharacters (e.g. ;, |, `, $()) break out of the intended command. Because embedded camera firmware typically runs its web/management daemons as root, injected commands generally execute with full device privileges.

Executive ViewAI
Tenda CP3 IP cameras running firmware 27.5.57.101 contain a command injection vulnerability allowing attackers with administrative credentials to achieve arbitrary code execution. Organizations deploying these cameras risk compromise of surveillance infrastructure, potential lateral movement into corporate networks, and unauthorized access to camera systems and connected network segments.
No vendor-released patch identified at time of analysis. Interim mitigations: implement network segmentation isolating cameras from production systems; enforce least-privilege administrative access with credential rotation; disable remote management and restrict access to camera interfaces to trusted personnel only; deploy network monitoring and logging on camera administrative sessions; consider temporary decommissioning of highest-risk deployments until patched firmware is available.
