DescriptionCVE.org

rsync before 3.5.0 contains an arbitrary file read vulnerability that allows attackers to read files accessible to the rsync daemon process by exploiting symlink following in input configuration file handling including --files-from, --password-file, and filter merge files. Attackers can place a symlink at a predictable --files-from or --password-file path, or supply a --files-from path that escapes the daemon module root, to read arbitrary files accessible to the rsync process.

AnalysisAI

Arbitrary file read in rsync before 3.5.0 enables attackers with local low-privilege access to read files accessible to the rsync daemon process by exploiting improper symlink resolution in input configuration file handling. The vulnerability affects --files-from, --password-file, and filter merge file paths, allowing placement of a symlink at a predictable argument path or supply of a --files-from path that escapes the daemon module root. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Gain local low-privilege system access
Delivery
Identify predictable --files-from or --password-file path used by rsync daemon
Exploit
Place attacker-controlled symlink at that path pointing to target sensitive file
Execution
Trigger or wait for rsync daemon to process configuration
Persist
Daemon follows symlink, reads arbitrary file contents
Impact
Retrieve exfiltrated data

Vulnerability AssessmentAI

Exploitation Exploitation requires local system access with at least low-level privileges (CVSS PR:L, AV:L), confirming this is not remotely exploitable by unauthenticated attackers. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N) scores 8.4, reflecting low attack complexity and no special attack requirements beyond local low-privilege access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user with a low-privilege account on a system running an rsync daemon places a symlink at a predictable path expected by a --files-from or --password-file argument - for example, pointing to /etc/shadow or an application's private key file. When the rsync daemon processes the next scheduled or triggered sync job, it follows the symlink and reads the target file as part of its configuration handling, exposing the file contents to the attacker. …
Remediation Vendor-released patch: rsync 3.5.0. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit all systems running rsync and identify those with versions prior to 3.5.0, prioritizing inventory of systems running rsync daemon with local user access. …
