Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: OpenRemote < 1.22.0 suffers from **Expression Injection** in its rule engine. ๐ **Consequences**: Attackers can achieve **Remote Code Execution (RCE)** on the server, leading to total system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-94** (Code Injection). The flaw lies in the **Rule Engine**, where two interrelated expressions are not properly sanitized, allowing malicious code injection.
Q3Who is affected? (Versions/Components)
๐ข **Affected**: **OpenRemote** IoT Platform. Specifically, all versions **prior to 1.22.0**. ๐ฆ Component: The internal **Rule Engine** module.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: With access, hackers can execute **arbitrary code** on the server. This grants full control over the IoT platform, risking data theft, manipulation, or further lateral movement.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **Medium**. Requires **Low Complexity** and **Network** access. โ ๏ธ **Prerequisite**: Requires **Low Privileges** (PR:L) to exploit.โฆ
๐ **Public Exploit**: **No**. The provided data shows an empty `pocs` array. While advisory links exist, no public Proof-of-Concept (PoC) or wild exploitation code is currently available.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for **OpenRemote** instances running version **< 1.22.0**. Check if the **Rule Engine** is exposed and accessible. Look for version banners in HTTP headers or API responses.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **Yes**. The vulnerability is fixed in **OpenRemote 1.22.0**. ๐ฅ **Action**: Upgrade immediately to version 1.22.0 or later via the official GitHub releases.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: If upgrading is impossible, **restrict network access** to the Rule Engine. Enforce **strong authentication** and limit user privileges. Isolate the IoT platform from critical networks.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. CVSS Score indicates **Critical** impact (C:H, I:H, A:H). Although auth is required, the ease of exploitation (AC:L) and severity of RCE make immediate patching essential.
