Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Local File Inclusion (LFI) in 'Build App Online' plugin. ๐ **Consequences**: Attackers can read sensitive server files, leading to full system compromise, data theft, and potential remote code execution.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-98 (Improper Control of Filename for Include/Require). โ **Flaw**: Poor validation of filenames in PHP `include`/`require` statements allows malicious input manipulation.
๐ **Attacker Capabilities**: Read arbitrary local files (e.g., `/etc/passwd`, config files). ๐ **Impact**: High Confidentiality, Integrity, and Availability loss (CVSS H/I/A: H).
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: LOW. ๐ **Network**: AV:N (Network exploitable). ๐ **Auth**: PR:N (No Privileges required). ๐ค **UI**: UI:N (No User Interaction needed).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: No specific PoC listed in data. ๐ **Status**: Referenced by Patchstack DB. โ ๏ธ **Risk**: High likelihood of wild exploitation due to low barrier.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for 'Build App Online' plugin version. ๐งช **Test**: Look for LFI patterns in HTTP requests targeting plugin endpoints. ๐ **Tool**: Use vulnerability scanners detecting CWE-98.
Q8Is it fixed officially? (Patch/Mitigation)
๐ง **Fix**: Update plugin to version **>1.0.23**. ๐ข **Source**: Vendor release or Patchstack advisory. โ **Action**: Immediate patching recommended.
Q9What if no patch? (Workaround)
๐ซ **No Patch?**: Disable the plugin immediately. ๐ **Mitigation**: Restrict file access permissions. ๐งฑ **WAF**: Block LFI payloads (`../`) at the web server level.
