TinyServer is prone to multiple vulnerabilities.
A directory traversal issue is present in TinyServer that could allow a remote user to view or download any file to which the server has access.
A denial of service issue exists due to the failure of the server to check input strings received. Attackers can crash the server by simply sending malformed HTTP GET requests. Sending an HTTP GET request with excessively long data can also cause the server to fail. It is not known if this issue may also result in code execution.
A cross-site scripting issue is also present in the server. This could allow for theft of cookie-based authentication credentials or other attacks.
TinyServer contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate user input upon submission to the application. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
