Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OS Command Injection in Brivo ACS. <br>β‘ **Consequences**: Attackers can inject malicious commands via unneutralized special elements.β¦
π‘οΈ **Root Cause**: **CWE-78** (OS Command Injection). <br>β **Flaw**: Improper neutralization of special elements used in an OS command. The system fails to sanitize inputs correctly before execution.
Q3Who is affected? (Versions/Components)
π’ **Affected Vendor**: Brivo. <br>π¦ **Products**: ACS100, ACS300. <br>π **Versions**: 5.2.4 through 6.2.4.3. If you are in this range, you are at risk!
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Full OS command execution. <br>π **Privileges**: High. The CVSS vector (AV:A/AC:L/PR:L/S:C/C:H/I:H/A:H) indicates High Confidentiality, Integrity, and Availability impact.β¦
π΅οΈ **Public Exploit**: **No**. <br>π **PoC**: The provided data shows an empty `pocs` array. <br>π **Wild Exploit**: No evidence of widespread exploitation in the provided references.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: <br>1. Verify your Brivo ACS version. <br>2. Check if it falls between **5.2.4** and **6.2.4.3**. <br>3. Look for unusual system logs indicating command injection attempts.
π§ **No Patch Workaround**: <br>1. **Isolate**: Segment the network for ACS devices. <br>2. **Monitor**: Watch for anomalous command executions. <br>3. **Restrict**: Limit access to adjacent networks (since AV:A).
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. <br>π **Priority**: Immediate patching recommended. <br>β οΈ **Reason**: Low complexity, no user interaction, and high impact (C:H/I:H/A:H) make this a critical threat to physical security systems.
