Lifecycle Timeline
3DescriptionCVE.org
rsync 3.0.0 before 3.5.0 contains a null pointer dereference vulnerability in the daemon child process that allows remote attackers to crash the daemon by sending a file list whose first entry is a dot entry not typed as a directory. The daemon dereferences the first file list entry as a directory structure pointer without verifying the entry type, resulting in an invalid or uninitialized pointer dereference that terminates the client connection.
AnalysisAI
Remote unauthenticated crash of the rsync daemon affects all versions from 3.0.0 through 3.4.x. The daemon child process dereferences the first file list entry as a directory structure pointer without verifying its type, so a dot entry not typed as a directory triggers a null or uninitialized pointer dereference (CWE-908) that terminates the connection. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The rsync daemon must be running in daemon mode (started via `rsync --daemon` or a system service such as rsyncd.service) and reachable over the network on TCP 873. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) places this at the highest possible exploitability tier - unauthenticated, low complexity, no user interaction - making any internet-exposed rsync daemon trivially reachable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker connects to an exposed rsync daemon on TCP 873 and transmits a crafted file list in which the first entry is a dot ('.') without the directory type flag set. The daemon child process dereferences this entry as a directory structure pointer without type validation, immediately encountering a null or uninitialized pointer and crashing. … |
| Remediation | Vendor-released patch: rsync 3.5.0, confirmed as a major security release by the upstream project at https://github.com/RsyncProject/rsync/releases/tag/v3.5.0 and addressed in the security advisory at https://github.com/RsyncProject/rsync/security/advisories/GHSA-p4v4-qxw9-q72m. … Detailed patch versions, workarounds, and compensating controls in full report. |
