Description
The mod_auth module in OTP's inets httpd server, when configured with dets or mnesia authentication backends and multiple directory configuration blocks, collapses all directory blocks into a single shared user/group namespace. A user added to one protected directory is accepted as valid for all other protected directories on the same server instance. This issue affects OTP from OTPÂ 17.0 before OTPÂ 27.3.4.17, from OTPÂ 28.0 before OTPÂ 28.5.0.6, and from OTPÂ 29.0 before OTPÂ 29.0.6, corresponding to inets from 5.10 before 9.3.2.7, from 9.4 before 9.6.2.3, and from 9.7 before 9.7.2. Whether OTP before OTPÂ 17.0, corresponding to inets before 5.10, is affected is unknown.
