Has anyone done an analysis of the rsync CVE-2022-29154 (which "allows
malicious remote servers to write arbitrary files inside the directories
of connecting peers") and its potential impact on RPKI validators? It
looks like both Debian [1] and Ubuntu [2] opted *not* to patch rsync in
their release/security package streams.
Are rsync-based (or rsync-fallback, which I believe is still required
for all RPKI validators?) RPKI validators all vulnerable to takeover
from this, or is there some reason why this doesn't apply to RPKI
validation?
The attacker is still limited to the target directory. The attacker can
send files that were excluded or not requested, but they still end up in
the target directory. RPKI validators download stuff in a dedicated
download directory (but it may be shared with several peers), so they
should be safe.
