Authentication Bypass

Description

xdg-dbus-proxy is a filtering proxy for D-Bus connections. Prior to 0.1.7, a policy parser vulnerability allows bypassing eavesdrop restrictions. The proxy checks for eavesdrop=true in policy rules but fails to handle eavesdrop ='true' (with a space before the equals sign) and similar cases. Clients can intercept D-Bus messages they should not have access to. This vulnerability is fixed in 0.1.7.

Analysis

Policy parser vulnerability in xdg-dbus-proxy prior to 0.1.7 allows authenticated local users to bypass eavesdrop restrictions and intercept D-Bus messages by exploiting improper whitespace handling in policy rule parsing. The proxy fails to normalize eavesdrop policy directives, permitting attackers to craft malformed policies (e.g., eavesdrop ='true' with spacing variations) that evade the eavesdrop=true access control checks. …
