Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A buffer error in `mod_uwsgi` within Apache HTTP Server. <br>๐ฅ **Consequences**: Attackers can disclose sensitive info and potentially execute arbitrary code remotely. It's a critical integrity risk!
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Buffer overflow/overlow error specifically in the `mod_uwsgi` module. <br>๐ **CWE**: Not explicitly mapped in data, but technically a memory handling flaw allowing out-of-bounds access.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: Apache HTTP Server versions **2.4.32 through 2.4.44**. <br>โ๏ธ **Component**: Specifically the `mod_uwsgi` (or `mod_proxy_uwsgi`) module. If you don't use uwsgi, you might be safe!
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hackers' Power**: <br>1. **Info Disclosure**: Access sensitive server data. <br>2. **RCE**: Execute arbitrary code on the server. <br>๐ **Privilege**: Remote execution without authentication required.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **LOW**. <br>๐ **Auth**: No authentication needed. <br>โ๏ธ **Config**: Only requires `mod_uwsgi` to be enabled. Crafted requests are all it takes.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exp?**: **YES**. <br>๐ **PoC**: Available on GitHub (e.g., `masahiro331/CVE-2020-11984`). <br>๐ **Status**: Wild exploitation is possible via crafted HTTP requests.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: <br>1. Check Apache version (2.4.32-2.4.44). <br>2. Verify if `mod_uwsgi` is loaded. <br>3. Use scanners like Nuclei templates to detect the specific buffer error pattern.
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Official Fix**: **YES**. <br>๐ **Timeline**: Patched after Aug 2020. <br>๐ข **Action**: Upgrade to a version newer than 2.4.44 immediately. Fedora and other vendors issued advisories.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: <br>1. **Disable Module**: Remove or disable `mod_uwsgi` if not strictly needed. <br>2. **WAF**: Block crafted requests targeting uwsgi endpoints. <br>3. **Network**: Restrict access to uwsgi ports.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. <br>โ ๏ธ **Priority**: Critical. Since PoCs are public and it allows RCE, patch immediately. Don't wait for a scheduled maintenance window!
