Yaws Web Server .yaws Script Null Byte Request Source Code Disclosure

medium Nessus Plugin ID 18522

Language:

Synopsis

The remote web server is affected by an information disclosure flaw.

Description

The remote host is running the Yaws web server.

The remote version of this software is vulnerable to a source code disclosure issue. By requesting a '.yaws' script following by %00, an attacker may force the remote server to disclose the source code of that script.

Since scripts may contain sensitive information such as logins and passwords, an attacker may exploit this flaw to obtain some credentials on the remote host or a better understanding of the security of the '.yaws' scripts.

Solution

Upgrade to YAWS 1.56 or newer.
