Security readout for executives and security teams
Plain-English summary
Synology Hyper Backup before 4.1.2-4036 has a path traversal flaw. An attacker already logged in with administrator privileges could write certain files outside the intended location. The reported impact is limited integrity change, not data theft or service outage.
Executive priority
Treat as a routine but timely update. Business risk is moderate because exploitation needs admin privileges and reported impact is limited, but backup infrastructure is sensitive and should be kept current.
Technical view
CVE-2024-47263 is CWE-22 in the Backup.Repository webapi component. It is network-accessible, low complexity, requires high privileges, and no user interaction. CVSS 3.1 is 4.1. The CVE states remote authenticated administrators can write specific files containing non-sensitive information via unspecified vectors.
Likely exposure
Exposure is limited to Synology Hyper Backup installations earlier than 4.1.2-4036, primarily where administrative accounts or management access are reachable by untrusted users or compromised credentials.
Exploitation context
No active exploitation is indicated in the provided sources, and the CVE is not listed as KEV. Exploitation requires authenticated administrator privileges, reducing likelihood but making compromised admin accounts relevant.
Researcher notes
Public details are sparse. The vector is described as unspecified, and sources do not provide exploit mechanics. Focus validation on version status, administrative exposure, and whether Backup.Repository webapi is present in affected Hyper Backup builds.
Mitigation direction
- Upgrade Synology Hyper Backup to 4.1.2-4036 or later.
- Review Synology release notes and advisory guidance for your model and DSM version.
- Restrict administrative access to trusted networks and accounts.
- Audit Hyper Backup administrator accounts for unnecessary privileges.
Validation and detection
- Inventory Synology systems running Hyper Backup.
- Confirm installed Hyper Backup version is 4.1.2-4036 or later.
- Verify administrative access is limited to authorized users.
- Review recent administrative activity for unexpected Hyper Backup configuration changes.

CWE-22: File access and web shell behavior lookup
File traversal and upload weaknesses can lead teams to review file, web shell, execution, and collection telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupFile access behavior lookup
The CVE wording references file access or upload behavior, so file telemetry and web shell review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
