Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: elFinder is an open-source AJAX file manager. This vulnerability allows **Remote Code Execution (RCE)**.โฆ
๐ก๏ธ **Root Cause**: **CWE-918** (Server-Side Request Forgery / Command Injection). The flaw lies in how elFinder handles ZIP archive arguments, allowing attackers to inject malicious system commands. ๐
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Studio-42**'s **elFinder** product. Specifically, versions up to **2.1.58** are impacted. It affects servers running the PHP connector with minimal configuration. ๐ฆ
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Full **RCE**. Hackers can write web shells (e.g., `shell.php`), execute system commands (`whoami`, etc.), and gain complete control over the host server. ๐ดโโ ๏ธ
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. No authentication (PR:N) or user interaction (UI:N) is required. It is easily exploitable over the network. ๐
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploits**: **YES**. POCs are available on GitHub (e.g., `nickswink/CVE-2021-32682`) and Nuclei templates. Automated tools can detect and exploit this easily. ๐
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for elFinder PHP connectors. Look for the 'Create archive' -> 'Zip archive' feature. Use Nuclei templates or specific POC scripts to test for command injection via ZIP filenames. ๐งช
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **YES**. Studio-42 released a fix. Refer to the GitHub commit `a106c35` and the GitHub Security Advisory `GHSA-wph3-44rj-92pr` for the patched version. ๐ฉน
Q9What if no patch? (Workaround)
๐ง **No Patch?**: **Mitigation**: Disable the 'archive' command in elFinder configuration if possible. Restrict access to the elFinder connector via firewall/WAF. Block outbound connections if possible. ๐
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. CVSS Score is **High** (9.8 implied by H/I/H). Public exploits exist. Immediate patching or mitigation is required to prevent server takeover. โณ
