3DescriptionCVE.org
rsync before 3.5.0 contains multiple command and argument injection vulnerabilities that allow attackers to execute arbitrary commands by supplying malicious input through several code paths, including the RSYNC_CONNECT_PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell command newline injection. Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values such as hostnames and hostspecs to execute arbitrary commands under the privileges of the rsync process or the invoking user.
AnalysisAI
Arbitrary command execution in rsync before 3.5.0 arises from multiple unsanitized code paths - the RSYNC_CONNECT_PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell newline injection - that let an attacker who controls hostnames, hostspecs, or related input inject shell metacharacters or newlines and run commands as the rsync process or invoking user. VulnCheck reported the cluster of CWE-78 flaws, which are fixed together in the major security release v3.5.0. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to control at least one specific input to a vulnerable code path: the RSYNC_CONNECT_PROG environment variable, a daemon hook configuration, the target host passed to the rsync-ssl wrapper, or a hostname/hostspec used in remote-shell command assembly - with shell metacharacters or newline characters embedded in that value. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 vector (AV:N/AC:H/AT:N/PR:N/UI:N, VC:H/VI:H/VA:H) yields 9.2 and signals high technical impact with no privileges required, but AC:H correctly flags that exploitation is not trivial: the attacker must control the hostname/hostspec, environment, or the server the victim connects to, rather than fire a single unauthenticated packet at a listening service. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An automation script or web-facing service builds an rsync command from a user-supplied hostname; an attacker submits a hostspec containing shell metacharacters or an embedded newline, and rsync expands it through one of the vulnerable paths (e.g. RSYNC_CONNECT_PROG or the rsync-ssl wrapper), executing the attacker's commands under the invoking user's privileges. … |
| Remediation | Upgrade to rsync 3.5.0 or later, which fixes all of the reported command- and argument-injection paths together (Vendor-released patch: 3.5.0); see https://github.com/RsyncProject/rsync/releases/tag/v3.5.0 and the advisory https://github.com/RsyncProject/rsync/security/advisories/GHSA-5hcf-7xxm-rmqq, and apply the corresponding distribution package update where available. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running rsync and identify those on versions prior to 3.5.0, prioritizing production file synchronization servers and backup infrastructure. …
