Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Directory Traversal in Output Messenger. <br>π₯ **Consequences**: Attackers can access sensitive files outside intended directories.β¦
π‘οΈ **CWE-24**: Improper Interpretation of Path. <br>π **Flaw**: The application fails to properly sanitize user-supplied input, allowing path traversal sequences (e.g., `../`) to escape the secure directory.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: Srimax / Output Messenger. <br>π¦ **Affected**: Versions **prior to 2.0.63**. <br>β **Safe**: Version 2.0.63 and above are patched.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hackers Can**: Read sensitive internal files. <br>π **Privileges**: No authentication required (PR:N). <br>π **Data**: Leaks confidential data stored in accessible directories.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: LOW. <br>π **Auth**: None required (PR:N). <br>π **Network**: Network accessible (AV:N). <br>π±οΈ **UI**: No user interaction needed (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exploit**: No PoC or Wild Exploit listed in data. <br>β οΈ **Risk**: Despite no public code, the low exploitation barrier makes it highly dangerous if discovered.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Output Messenger services. <br>π§ͺ **Test**: Attempt directory traversal requests (`../../etc/passwd` style) against file download endpoints.β¦
β **Fixed**: Yes. <br>π§ **Patch**: Upgrade to **Output Messenger 2.0.63** or later. <br>π **Ref**: Official advisory at outputmessenger.com/cve-2025-27920.
Q9What if no patch? (Workaround)
π‘οΈ **Workaround**: If patching is delayed, restrict network access to the service. <br>π« **Block**: Disable file sharing features if not essential. <br>π **WAF**: Use Web Application Firewall to block traversal patterns.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: MEDIUM-HIGH. <br>β±οΈ **Priority**: Patch immediately. <br>π **Reason**: No auth required + Network accessible = Easy target for automated scanners. Don't wait for a PoC!
