Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Arcane OS Command Injection. π **Consequences**: Attackers can execute arbitrary shell commands on the host system. This leads to total system compromise, data theft, or service disruption.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-78 (OS Command Injection). π₯ **Flaw**: The update service in Arcane fails to properly sanitize inputs, allowing malicious commands to be injected and executed by the system.
Q3Who is affected? (Versions/Components)
π― **Affected**: Arcane (Docker management software). π¦ **Versions**: All versions **prior to 1.13.0**. π’ **Vendor**: getarcaneapp.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: High. The vulnerability allows execution of **arbitrary shell commands**. π **Data**: Full access to underlying OS data, Docker containers, and potentially sensitive configuration files.β¦
β οΈ **Threshold**: Medium. π **Auth**: Requires Local Privileges (PR:L). π±οΈ **UI**: Requires User Interaction (UI:R). It is not remotely exploitable without authentication or user action.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exp?**: No public PoC or wild exploitation detected yet. π **Status**: References point to GitHub advisories and patches, but no active exploit code is available in the provided data.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Check your Arcane version. π **Action**: If version < 1.13.0, you are vulnerable. π **Scan**: Look for the 'update service' component in your deployment.β¦
β **Fixed**: Yes! π οΈ **Patch**: Fixed in **Arcane v1.13.0**. π₯ **Action**: Upgrade immediately to v1.13.0 or later. See GitHub release notes for details.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: Isolate the Arcane service. π« **Restrict**: Limit network access and user permissions. π **Disable**: If possible, disable the update service functionality until patching is feasible.β¦
π₯ **Urgency**: High. π¨ **Priority**: Immediate patching required. Although auth is needed, the impact (C:H, I:H, A:H) is critical. Do not delay upgrading to v1.13.0+.
