Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Path Traversal vulnerability in uWSGI. <br>π₯ **Consequences**: Attackers can read **arbitrary files** on the system by exploiting improper handling of `DOCUMENT_ROOT`.β¦
π¦ **Affected**: uWSGI versions **before 2.0.17**. <br>βοΈ **Component**: Specifically impacts the **PHP Plugin** when the `--php-docroot` configuration option is enabled.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hackers' Power**: Can view **any file** on the server. <br>π **Data Risk**: Sensitive configs, source code, or credentials exposed via crafted URLs containing `..` sequences.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **Low**. <br>π **Auth**: No authentication required. <br>βοΈ **Config**: Only requires the vulnerable `--php-docroot` setting. Simple URL manipulation is enough.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exp?**: **YES**. <br>π **Proof**: Multiple PoCs available on GitHub (e.g., `vulhub`, `nuclei-templates`, `exploit-db #44223`). Wild exploitation is feasible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for uWSGI servers running PHP with `--php-docroot`. <br>π§ͺ **Test**: Send requests with `../` in the URL path. If sensitive files are returned, you are vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: **YES**. <br>π οΈ **Patch**: Upgrade to **uWSGI 2.0.17** or later. The changelog confirms the fix for this specific DOCUMENT_ROOT handling issue.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Disable the `--php-docroot` option if possible. <br>π« **Mitigation**: Implement strict WAF rules to block `..` sequences in URLs targeting uWSGI endpoints.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. <br>β οΈ **Priority**: Critical for PHP/uWSGI setups. Immediate patching recommended due to easy exploitation and high impact (full file read).
