Felisify SambaBox: OS command injection
Summary
SambaBox versions before 5.4.1 contain an OS command injection vulnerability (CWE-78) that allows an attacker to run operating system commands on the affected host. Per NVD's CVSS 3.1 score of 8.8, the attack can be carried out over the network with low complexity, but requires low privileges, meaning an account on the application. Exploitation would impact confidentiality, integrity and availability. No exploitation has been confirmed and NVD analysis is still pending.
Affected
- SambaBox versions before 5.4.1 (CNA data; VulDB lists 5.0 through 5.4.0)
Fixed in
- Upgrade to SambaBox 5.4.1 or later (per CNA data and VulDB; verify via the vendor's download channel)
Workaround
- No vendor workaround found.
- Interim measure: restrict network access to the SambaBox service to trusted hosts and staff, and review accounts with access.
Exploitation
- No confirmed exploitation.
- Not listed in CISA KEV.
- EPSS score: 0.00906.
- No public proof of concept found.
Our recommendation
- Inventory all SambaBox installations and their versions.
- Upgrade to 5.4.1 or later as a priority.
- Until patched, restrict access to trusted networks and review accounts.
- Check whether SambaBox is reachable from the internet and remove public exposure if possible.
- Review logs for unusual process execution or unexpected activity on the SambaBox host.
- Monitor the vendor advisory, NVD analysis and KEV listings.
