File Enumeration Vulnerability in rsync by Red Hat

CVE-2024-12086

Summary

A vulnerability in rsync has been identified that allows a server to expose the contents of files located on a client's machine. This issue arises during the process of file synchronization, where the rsync server transmits checksums of its local files to a client for comparison, determining which files need to be transferred. By exploiting this vulnerability, an attacker can craft specific checksum values to coax the rsync server into divulging sensitive information about arbitrary files. This enables a potential attacker to reconstruct the data from these files byte by byte, posing a significant risk to the integrity and confidentiality of sensitive information.
