An unauthenticated remote attacker can exploit the vulnerability by sending PATH_CHALLENGE frames and manipulating the connection (e.g.
QUIC path validation (RFC 9000 Section 8.2) requires that the recipient of a PATH_CHALLENGE frame responds by sending a PATH_RESPONSE. 0.15.0 through 0.19.0 was discovered to be vulnerable to unbounded queuing of path validation messages, which could lead to excessive resource consumption. Inadequate validation of permissions when employing remote tools and macros via the context menu within Devolutions Remote Desktop Manager versions 2023.3.31 and earlier permits a user to initiate a connection without proper execution rights via the remote tools feature.
