CVE-2026-7610: Cleartext Transmission of Sensitive Information in TRENDnet TEW-821DAP
A vulnerability has been found in TRENDnet TEW-821DAP 1.12B01. This affects an unknown function of the file /www/cgi/ssi of the component Firmware Update. Such manipulation leads to cleartext transmission of sensitive information. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit has been disclosed to the public and may be used. The vendor explains: "That firmware version will only work on our hardware version v1.xR. We have already EOL that product 8 years ago and are no longer selling". This vulnerability only affects products that are no longer supported by the maintainer.
AI Analysis
Technical Summary
This vulnerability affects the TRENDnet TEW-821DAP router running firmware version 1.12B01. An unknown function within the /www/cgi/ssi component responsible for firmware updates transmits sensitive information in cleartext, which could be intercepted by remote attackers. The attack complexity is high, and exploitation does not require privileges or user interaction. The vendor has discontinued support for this hardware version (v1.xR) and no patches or fixes are available.
Potential Impact
Sensitive information may be exposed in cleartext during firmware update processes, potentially allowing remote attackers to intercept this data. However, exploitation is difficult due to high complexity. The vulnerability affects only an end-of-life product that is no longer sold or supported by TRENDnet, limiting the practical impact.
Mitigation Recommendations
No official fix or patch is available because the affected product is end-of-life and no longer supported by the vendor. Users should consider replacing the affected hardware with a supported device to mitigate risk. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance if any becomes available.
