Summary

CVE-2026-32838 is a high-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Edimax Gs-5008Pl Firmware. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32838 is a vulnerability in the Edimax GS-5008PL unmanaged PoE switch running firmware version 1.00.54 and prior versions. The issue stems from the web management interface using cleartext HTTP without TLS or SSL encryption, enabling interception of sensitive data. This is classified as CWE-319 (Cleartext Transmission of Sensitive Information) with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact over the network.

Attackers on the same local network as the affected device can exploit this by passively intercepting web management traffic. No privileges, user interaction, or special conditions are required beyond network access. Successful interception allows capture of administrator credentials and sensitive configuration data, potentially enabling unauthorized access or further network compromise.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

PR.DS-02 full match
prevents

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

prevents

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.

prevents

Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.

mitigates

Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.

mitigates

Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
