Name of the Vulnerable Software and Affected Versions
Vert.x-Web (affected versions not specified)
Description
The issue affects Vert.x-Web applications that serve files using
StaticHandler on Windows Operating Systems and Windows File Systems. When the mount point is a wildcard (*), an attacker can exfiltrate any class path resource. The problem arises from the Utils.java code, which returns user input without validation as the segment to lookup, allowing an attacker to build a valid path within the classpath by exploiting improper handling of ``. This issue only affects users deploying in Windows environments.Recommendations
As a temporary workaround, consider disabling the
StaticHandler function until a patch is available.
Restrict access to the StaticHandler module to minimize the risk of exploitation.
Avoid using the StaticHandler with wildcard mount points until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
