Siemens RUGGEDCOM CROSSBOW: SQL injection via firmware file name
Summary
RUGGEDCOM CROSSBOW, a secure access management solution for IED access, does not properly validate or sanitize the filename of uploaded firmware files. An authenticated attacker with specific privileges can execute arbitrary SQL commands on the underlying database. The CVSS v4.0 base score is 8.7, and Siemens rates the technical impact as total.
Affected
- RUGGEDCOM CROSSBOW, all versions below V6.0
Fixed in
- Update to V6.0 or later (Siemens support: https://support.industry.siemens.com/cs/ww/en/view/110006651/)
Workaround
Unknown.
Exploitation
- No evidence of exploitation in the wild found in the sources reviewed.
- No public proof of concept found.
- CISA SSVC: Exploitation none, Automatable no.
Our recommendation
- Check whether any CROSSBOW instances are in use, especially in energy or utility environments.
- Plan the update to V6.0 or later and apply it to all 11 CVEs in SSA-508506, not only CVE-2026-89198.
- Until the update is applied, restrict access to the CROSSBOW management interface to trusted admin networks.
- Review and limit accounts that are allowed to upload firmware.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
