Lifecycle Timeline
4DescriptionCVE.org
A vulnerability was identified in TRENDnet TEW-755AP up to 20260702. Affected by this issue is some unknown functionality of the file /cgi-bin/wan.cgi of the component ssi. Such manipulation of the argument cameo.wan.wan_pppoe_password_00 leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used.
AnalysisAI
Stack-based buffer overflow in TRENDnet TEW-755AP firmware (up to build 20260702) allows remote low-privileged attackers to corrupt stack memory via the cameo.wan.wan_pppoe_password_00 parameter in /cgi-bin/wan.cgi. A public proof-of-concept exploit script is confirmed on GitHub, materially lowering the bar for exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires low-privilege authenticated access to the device's HTTP web management interface - the CVSS 4.0 PR:L metric explicitly confirms that at least low-level credentials are needed; unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) establishes this as a low-complexity, network-reachable flaw requiring only low-privilege authentication with no user interaction - a high-priority combination. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege credentials to the TEW-755AP's web management interface sends a crafted HTTP POST request to /cgi-bin/wan.cgi, embedding an oversized string in the cameo.wan.wan_pppoe_password_00 parameter. The ssi CGI handler copies this value into a fixed stack buffer without bounds checking, overwriting the return address and redirecting execution flow. … |
| Remediation | No vendor-released patch has been identified at time of analysis - TRENDnet has not published a firmware update addressing this vulnerability in the available reference data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all TRENDnet TEW-755AP units deployed in your environment and confirm which are running firmware builds through 20260702; isolate affected devices from untrusted network segments and restrict administrative access to authorized personnel only. …
