Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OS Command Injection in InSAT MasterSCADA BUK-TS. π **Consequences**: Remote Code Execution (RCE). Attackers can take full control of the system via the MMadmServ Web interface.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-78 (OS Command Injection). π **Flaw**: The MMadmServ Web interface fails to sanitize input fields, allowing malicious commands to be executed directly on the OS.
Q3Who is affected? (Versions/Components)
π **Affected**: InSAT MasterSCADA BUK-TS. π·πΊ **Vendor**: InSAT (Russia). βοΈ **Component**: Industrial Automation Control System. Specific versions are not listed, but the product line is at risk.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full System Control. π **Data**: High Impact (C:H, I:H, A:H). Attackers can read, modify, or delete critical industrial data and execute arbitrary code with system-level privileges.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: LOW. π **Auth**: None Required (PR:N). π±οΈ **UI**: None Required. π‘ **Vector**: Network (AV:N). This is a critical, remote, unauthenticated vulnerability.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exp**: No PoC available in data. π **Refs**: CISA Advisory (ICSA-26-055-01) exists. While no code is public, the severity suggests high risk of future exploitation.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for InSAT MasterSCADA BUK-TS web services. π΅οΈ **Feature**: Look for the MMadmServ interface. π‘ **Test**: Check for command injection vectors in web parameters (use caution/proxy only).
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Fix**: Patch recommended. π **Date**: Published 2026-02-24. π’ **Source**: Refer to CISA ICSA-26-055-01 for official vendor guidance and patch availability.
Q9What if no patch? (Workaround)
π§ **Workaround**: Isolate the MMadmServ interface. π« **Block**: Restrict network access to the web port. π **Mitigate**: Implement strict WAF rules to block OS command injection patterns.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: CRITICAL. π¨ **Priority**: Immediate Action. CVSS Score is High (9.8 implied by H/I/H). Unauthenticated RCE in OT systems is a top-tier threat.
