Summary
Openfind SecuShare Pro version 4 contains an OS command injection vulnerability (CWE-78). An unauthenticated remote attacker can send crafted input to inject arbitrary operating system commands and run them on the server. The CVSS 4.0 score is 9.3 (critical), and the attack requires only network access to the server.
Affected
- SecuShare Pro version 4 (per the CVE record and TWCERT/CC). Exact affected build numbers: Unknown.
- Cloud edition (MailCloud including EaaS): not affected according to the vendor, as all environments have been updated.
Fixed in
- Standard edition: Unknown build number. Contact Openfind technical service for the update.
- Customized edition: Provide the installed version number to Openfind, who will supply the security patch.
- Cloud edition: Fully updated by the vendor.
Workaround
- Unknown. No vendor workaround is published in the reviewed sources.
- Until a patch is installed, restrict network access to the server to trusted networks or VPN and remove direct internet exposure.
Exploitation
- No known exploitation in the wild according to the reviewed sources. CISA SSVC lists exploitation as none and automatable as yes.
- VulDB reports no public exploit. This search was not exhaustive.
Our recommendation
- Check immediately whether any SecuShare Pro instance is reachable from the internet and remove that exposure.
- Identify the exact installed version and edition, then contact Openfind to obtain the patch.
- Restrict access to the server and monitor for unexpected child processes and outbound connections from the application service account.
- Verify the patch channel with Openfind or your reseller, because sources differ on it.
