Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: im-server < 1.4.3 has a **Code Issue** in file uploads. π **Consequences**: Improper filename sanitization leads to **Remote Code Execution (RCE)**. Critical integrity/availability loss.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-22** (Path Traversal/Improper Limitation). π **Flaw**: The system fails to properly clean user-supplied filenames during upload, allowing malicious paths.
Q3Who is affected? (Versions/Components)
π― **Affected**: **WildfireChat im-server**. π **Version**: All versions **prior to 1.4.3**. β **Fixed**: v1.4.3+.
Q4What can hackers do? (Privileges/Data)
π **Impact**: Full **Remote Code Execution**. π **Data**: Complete compromise of Confidentiality, Integrity, and Availability. Server takeover possible.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. π **Network**: Attack Vector is Network (AV:N). π **Auth**: Privileges Required are **None** (PR:N). No user interaction needed (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: **No public PoC** listed in data. π **References**: GitHub Advisory & Commit link provided, but no active wild exploitation confirmed yet.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **im-server** instances. π **Monitor**: Check file upload endpoints for unusual filename patterns or path traversal attempts in logs.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. π **Patch**: Upgrade to **im-server 1.4.3** or later. π **Source**: GitHub Release & Security Advisory.
Q9What if no patch? (Workaround)
π **Workaround**: If unpatched, **disable file upload** functionality temporarily. π« **Restrict**: Whitelist allowed file extensions and sanitize inputs manually if possible.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: **P1**. CVSS Score is **High** (H/H/H). Immediate patching required due to RCE risk and no auth requirement.
