Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Access Control Error in ThinkPHP. π **Consequences**: Remote Command Execution (RCE). Attackers can run arbitrary system commands via URL parameters.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper Access Control. The `invokefunction` functionality allows dangerous function calls (like `call_user_func_array`) without sufficient validation.β¦
π¦ **Affected**: ThinkPHP versions **before 3.2.4**. π± **Specifics**: Used in Open Source BMS v1.1.1 and other devices. π¨π³ **Vendor**: TopThink Information Technology.
Q4What can hackers do? (Privileges/Data)
π» **Hacker Power**: Full **Remote Command Execution**. π€ **Privileges**: Can execute system commands (e.g., `system()`). π **Data**: Potential full server compromise and data theft.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. π **Auth**: No authentication required (Remote). βοΈ **Config**: Exploitable via simple URL manipulation (`s=index/...`).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exp**: **YES**. π **Sources**: Exploit-DB (46488), PacketStorm, GitHub PoCs. π **Wild Exploitation**: High risk due to simple payload structure.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `invokefunction` in URLs. π οΈ **Tools**: Use Nuclei templates (CVE-2019-9082.yaml). π‘ **Indicator**: Look for `call_user_func_array` in request parameters.
