CVE-2024-11398
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in OTP reset functionality in Synology Router Manager (SRM) before 1.3.1-9346-9 allows remote authenticated users to delete arbitrary files via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA path traversal vulnerability exists in the OTP (One-Time Password) reset functionality of Synology Router Manager (SRM) versions prior to 1.3.1-9346-9. An authenticated remote attacker can manipulate file paths during the OTP reset process to delete arbitrary files on the system by using directory traversal sequences (e.g., ../../) in the file path parameters.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check SRM firmware versionLog into the Synology Router Manager web interface, then navigate to Control Panel > System > Information to view the current firmware version. Alternatively, run 'netstat -i' or check the kernel version via CLI.Affected if The installed version is 1.3.0 through 1.3.1-9346 (inclusive), meaning it falls within >= 1.3, < 1.3.1-9346 or equals exactly 1.3.1-9346.
-
Verify OTP reset feature accessibilityCheck if the One-Time Password (OTP) reset functionality is available on the SRM system. This is typically found in the SRM web interface under VPN > VPN Plus Server or User accounts settings where OTP reset options exist.Affected if OTP reset functionality is accessible to authenticated users on the system.
-
Confirm authentication method for OTP resetExamine the SRM user authentication configuration to determine if the OTP reset endpoint accepts requests from authenticated users without additional verification. Check the web application access controls and API permissions.Affected if Authenticated users can access and trigger the OTP reset process without extra security constraints.
The environment is affected if the SRM version is 1.3.0 through 1.3.1-9346 (inclusive) and the OTP reset functionality is accessible to authenticated users, allowing them to manipulate file paths via directory traversal sequences.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.3.1-9346
Apply the vendor-supplied SRM firmware update to version 1.3.1-9346-9 or later to patch the path traversal vulnerability in the OTP reset functionality.
1.3.1-9346-9 or later
- 1. Log in to the Synology Router Manager (SRM) web interface as an administrator
- 2. Navigate to Control Panel > System > Update & Restore
- 3. Check for available updates
- 4. Install version 1.3.1-9346-9 or later to remediate the path traversal vulnerability in the OTP reset functionality
