Arbitrary script execution in logged-in browsers
Published Jul 28, 2026 · Updated Jul 28, 2026
Reflected cross-site scripting in five ELECOM WAB access points allows attackers to execute arbitrary scripts in a logged-in user's browser. Published advisories identify only the WebUI configuration interface and do not disclose which request parameter is reflected or where output encoding fails. WAB-I1750-PS, WAB-M2133, and WAB-S1167-PS 2.0.5 and earlier are affected, as are WAB-M1775-PS and WAB-S1775 2.1.9 and earlier; exploitation requires adjacent-network access and passive interaction from a logged-in user.
