CyberRota Analysis

AI-Generated

The mod_auth module in OTP's inets HTTP server is vulnerable when configured with dets or mnesia authentication backends, allowing users added to one protected directory to gain access to all other protected directories on the same server instance due to a shared user/group namespace. This could lead to unauthorized access across multiple directories, compromising the security of sensitive data. Organizations using affected versions of OTP, particularly those with multiple directory configurations, should prioritize patching this vulnerability to mitigate potential risks.

Original NVD 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 OTP 17.0 before OTP 27.3.4.17, from OTP 28.0 before OTP 28.5.0.6, and from OTP 29.0 before OTP 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 OTP 17.0, corresponding to inets before 5.10, is affected is unknown.
