Why it matters

CVE-2026-89197 allows authenticated attackers with specific privileges to execute arbitrary SQL commands on RUGGEDCOM CROSSBOW systems, requiring defenders to verify exposure and assess potential impact.

• Potential for unauthorized SQL command execution
• Possible data breaches or system modifications
• Need for verification of system exposure and user privileges
• Importance of updating notification conditions to prevent exploitation

Technical summary

The vulnerability in RUGGEDCOM CROSSBOW (all versions < V6.0) allows an authenticated attacker with specific privileges to execute arbitrary SQL commands due to improper input validation in notification conditions. This could lead to potential data breaches or system modifications.
