CyberRota Analysis

AI-Generated

Rsync versions prior to 3.5.0 are vulnerable to a time-of-check to time-of-use (TOCTOU) race condition, which allows attackers to manipulate destination path components and redirect file writes to unintended locations. This vulnerability can lead to unauthorized file access or data corruption, particularly if an attacker can substitute a symlink in the destination path. Organizations using affected versions of rsync should prioritize updating to mitigate potential exploitation risks.

Original NVD Description

rsync before 3.5.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability in the non-daemon receiver's destination directory handling that allows an attacker who can manipulate destination path parent components to redirect file writes to unintended locations. Attackers can substitute a symlink for a component of the destination path between the path resolution and chdir() call, causing the receiver's working directory to be established outside the intended destination tree so that subsequent relative-path file writes land in unintended filesystem locations.
