Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hackers Can**: Read sensitive internal files. <br>๐ **Privileges**: No authentication required (PR:N). <br>๐ **Data**: Leaks confidential data stored in accessible directories.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: LOW. <br>๐ **Auth**: None required (PR:N). <br>๐ **Network**: Network accessible (AV:N). <br>๐ฑ๏ธ **UI**: No user interaction needed (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exploit**: No PoC or Wild Exploit listed in data. <br>โ ๏ธ **Risk**: Despite no public code, the low exploitation barrier makes it highly dangerous if discovered.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Output Messenger services. <br>๐งช **Test**: Attempt directory traversal requests (`../../etc/passwd` style) against file download endpoints.โฆ
