access to the affected interface may cause memory corruption, service instability, or information disclosure. Successful exploitation may allow remote code execution or denial-of-service.
Mitigating Controls (NIST 800-53 r5)AI
Directly enforces input validation mechanisms to prevent crafted requests from causing out-of-bounds memory access in the web interface.
Implements memory protection techniques like address space randomization to mitigate out-of-bounds writes leading to memory corruption or RCE.
Ensures timely identification, reporting, and patching of flaws like this input validation vulnerability via firmware updates.
Security SummaryAI
CVE-2026-1668 is a vulnerability in the web interface on multiple Omada switches, where certain external inputs are not adequately validated. This deficiency can lead to out-of-bounds memory access when processing crafted requests. Under specific conditions, the flaw may result in unintended command execution. The issue is linked to CWE-20 (Improper Input Validation) and CWE-787 (Out-of-bounds Write), with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
An unauthenticated attacker with network access to the affected interface can exploit this vulnerability to cause memory corruption, service instability, or information disclosure. Successful exploitation may allow remote code execution or denial-of-service.
