Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: MajorDoMo has an **Unauthenticated Remote Code Execution (RCE)** flaw.β¦
π‘οΈ **Root Cause**: **Command Injection** in `thumb.php`. π‘ **Flaw**: The module fails to properly sanitize shell metacharacters in input, allowing malicious commands to be injected and executed by the underlying OS.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: MajorDoMo (Open-source DIY smart home platform). π **Versions**: All versions **before commit 0662e5e**. π **Context**: Popular among Raspberry Pi users for home automation.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: **Unauthenticated** access means no login is needed.β¦
π **Threshold**: **LOW**. π **Auth**: No authentication required. π― **Config**: Exploitable via the `thumb.php` endpoint directly. This makes it extremely easy to exploit for anyone scanning the internet.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: **YES**. π **PoC**: Available on GitHub (e.g., Chocapikk/CVE-2023-50917). π‘ **Scanners**: Nuclei templates exist.β¦
π **Self-Check**: Scan for the `thumb.php` endpoint. π§ͺ **Test**: Send requests with shell metacharacters (e.g., `;`, `|`) to see if commands execute.β¦
π§ **Fixed?**: **YES**. π **Patch**: Official fix committed in MajorDoMo repository. π **Version**: Update to version **0662e5e** or later to mitigate the issue.β¦
π₯ **Urgency**: **CRITICAL**. β οΈ **Priority**: **Immediate Action Required**. π¨ **Reason**: Unauthenticated RCE with public PoCs. π **Action**: Patch immediately or isolate the service to prevent exploitation.
