Exploitation Conditions

Exploitation requires network reachability to the camera's web management interface and valid low-privilege credentials (confirmed by PR:L in the CVSS 4.0 vector). The vulnerable code path is triggered via the Currenttime parameter in the /cgi-bin/admin/set_time.cgi CGI handler - no special non-default camera configuration is required beyond the web interface being accessible. Factors that limit exploitation: the PR:L requirement means unauthenticated exploitation is not supported by the available data - an attacker must first acquire valid login credentials; cameras placed behind NAT without port forwarding, or on isolated IoT VLANs with no management-plane access from untrusted networks, are not directly reachable. Cameras using non-default, unique credentials are harder to compromise at the credential-acquisition stage, though the overflow itself imposes no additional configuration prerequisite once authenticated access is achieved.

Impact

The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) places exploitation within reach of any attacker who obtains low-privilege credentials - no special conditions, no user interaction, no complex attack preparation. The E:P supplemental metric aligns with the confirmed public POC, which materially lowers the attacker skill bar. High impact across all six CIA metrics (VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) reflects not just full camera compromise but potential for network-level lateral movement from a pivoted device. EPSS data was not supplied; given the public POC and the ease of exploitation, a moderate-to-elevated EPSS score would be expected. The absence of a CISA KEV listing means active mass exploitation is not confirmed, but the public exploit makes opportunistic targeting realistic. IP cameras are routinely under-segmented in enterprise and SMB environments, and even a small IT team managing a distributed camera deployment should treat this as an urgent remediation priority given the combination of network accessibility, low privilege requirement, and full-compromise impact. Note: the CVSS wildcard CPE suggests broader version impact than just 11.03.03, but this is not independently confirmed.

Exploit ScenarioDerived

An attacker who has obtained low-privilege credentials to the TV-IP751WIC web interface - through credential stuffing, default password use, or prior phishing - sends an HTTP POST request to /cgi-bin/admin/set_time.cgi with an oversized Currenttime parameter, triggering a stack buffer overflow in alphapd. The attacker overwrites the return address with a controlled value, redirecting execution to shellcode or a ROP gadget chain, achieving arbitrary code execution with alphapd's runtime privileges on the camera. The public proof-of-concept script (poc-time-injection.py at https://github.com/meishigana/CVE/blob/main/team15_20260702/07_751wic-apd-time-cmdi/poc/poc-time-injection.py) automates this attack.

AnalysisAIv1 – Aug 19, 2026

Stack-based buffer overflow in TRENDnet TV-IP751WIC firmware 11.03.03 allows remote low-privileged attackers to achieve arbitrary code execution by sending a crafted value in the Currenttime parameter to the /cgi-bin/admin/set_time.cgi endpoint handled by the alphapd daemon. The CVSS 4.0 score of 8.6 reflects high impact across confidentiality, integrity, and availability for both the compromised device and subsequent systems in its network segment. A public proof-of-concept exploit script is confirmed available on GitHub, though this vulnerability is not currently listed in the CISA KEV catalog.

RemediationAI

No vendor-released patch has been identified at time of analysis. Administrators should immediately restrict network access to the camera's HTTP/HTTPS management interface by isolating affected devices behind a firewall with strict ACLs, blocking inbound access to CGI endpoints from untrusted network segments - this eliminates the AV:N attack surface while preserving device functionality. If web-based administration is not operationally required, disabling it entirely removes the vulnerable endpoint; note this may prevent remote configuration workflows. Rotating and tightly scoping low-privilege credentials reduces the PR:L exposure, limiting who can trigger the vulnerable code path. Monitor VulDB (https://vuldb.com/cve/CVE-2026-76584) and TRENDnet's official firmware download page for a patched release. Do not rely on obscurity - the public POC lowers attacker barriers significantly.

Technical ContextAI · show details

The vulnerability resides in alphapd, the embedded CGI web daemon included in TRENDnet IP camera firmware. The /cgi-bin/admin/set_time.cgi handler accepts a Currenttime parameter for time configuration but performs no bounds checking before copying the user-supplied value into a fixed-size stack buffer. CWE-121 (Stack-Based Buffer Overflow) identifies the root cause: attacker-controlled data overwrites the stack frame including the saved return address, redirecting execution to attacker-supplied shellcode or a ROP chain. The affected product is confirmed by CPE string cpe:2.3:a:trendnet:tv-ip751wic:*:*:*:*:*:*:*:* - the wildcard version field implies all firmware versions may be vulnerable, with 11.03.03 specifically named in the disclosure.

Executive ViewAI

Why It Matters

The TRENDnet TV-IP751WIC network camera running firmware 11.03.03 contains a remotely exploitable buffer overflow vulnerability (CVSS 8.6) enabling arbitrary code execution and complete device takeover. Compromised cameras become network access points for attackers to intercept surveillance traffic, launch lateral attacks on internal systems, and undermine physical security monitoring. Organizations using these devices face immediate operational and compliance risk requiring urgent inventory and mitigation.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: segment affected cameras to a dedicated, restricted VLAN with egress filtering; implement strong authentication on all camera management systems; disable remote administrative interfaces where possible; monitor network traffic from affected devices for suspicious connections; maintain offline backups of security footage independent of camera storage; and establish incident response procedures for potential device compromise detection and remediation.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
