Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Path Traversal (LFI) flaw in IceWarp Mail Server. <br>π₯ **Consequences**: Attackers can read files outside the intended directory, potentially exposing sensitive server data or configuration files.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper filtering of resource/file paths. <br>π **CWE**: Path Traversal (CWE-22). The system fails to sanitize special elements like `..\` in URLs.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: IceWarp Mail Server. <br>π **Versions**: Version 10.4.4 and earlier. <br>π’ **Vendor**: IceWarp (USA).
Q4What can hackers do? (Privileges/Data)
π **Attacker Action**: Access restricted directories. <br>π **Data Risk**: Local File Inclusion (LFI). Can read arbitrary files on the server via the `webmail/calendar/minimizer/index.php` endpoint.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: Low. <br>π **Auth**: Likely requires no authentication or low privileges, as it targets a public webmail component. <br>π **Access**: Remote exploitation via HTTP requests.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: YES. <br>π **PoC**: Available on GitHub (ProjectDiscovery Nuclei templates & JameeNabbo exploits). <br>π **Wild Exp**: High risk due to simple `..\` payload injection.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for IceWarp Mail Server versions β€ 10.4.4. <br>π§ͺ **Test**: Send request to `webmail/calendar/minimizer/index.php?style=..\` and check for file content leakage in response.
π₯ **Urgency**: HIGH. <br>π **Priority**: Critical for exposed mail servers. <br>β³ **Time**: Exploits are public and simple. Immediate patching or mitigation is recommended to prevent data leakage.
