Icewarp · Icewarp Mail Server · CVE-2010-5334
**Name of the Vulnerable Software and Affected Versions**
IceWarp Webclient versions prior to 10.2.1
**Description**
The issue allows for directory traversal, potentially resulting in the loss of confidential data from IceWarp Mailserver and the operating system. Input passed via the ` c` parameter to "basic/index.html" is not properly sanitized, enabling exploitation to browse the partition where IceWarp is installed and read arbitrary files.
**Recommendations**
For versions prior to 10.2.1, update to version 10.2.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the "basic/index.html" endpoint to minimize the risk of exploitation. Avoid using the ` c` parameter in the affected endpoint until the issue is resolved.
