The vulnerability CVE-2024-12086 affects the rsync component used in Red Hat Discovery. It enables an attacker who controls an rsync server to enumerate the contents of arbitrary files on a client machine during file transfer. This occurs because the rsync server sends checksums of local data to the client to determine which data to send. By crafting special checksum values, the attacker can reconstruct file data byte-by-byte from the client's responses. The attack complexity is high, requiring control of the server and careful checksum manipulation. The impact is limited to information disclosure of file contents; no code execution or privilege escalation is possible. Red Hat has not provided a patch or mitigation that meets their criteria for ease of use and applicability.

An attacker controlling an rsync server can enumerate arbitrary files on a client machine by exploiting the checksum exchange mechanism during file synchronization. This leads to confidentiality loss of client file data. The attack does not allow execution of arbitrary code or privilege escalation. The vulnerability is rated as moderate by Red Hat due to the requirement for attacker-controlled servers and the complexity of the attack. There are no known exploits in the wild.

Currently, Red Hat has not provided an official fix or mitigation that meets their criteria for deployment and stability. Users should avoid interacting with untrusted or compromised rsync servers to reduce risk. Monitor Red Hat advisories for future updates or patches. No direct mitigation is available at this time.
