CVE-2016-10561

Vulnerability

Bitty, a development web server similar to python -m SimpleHTTPServer, in version 0.2.10 contains a directory traversal vulnerability. The bug is triggered by manipulating the URL path in GET requests, allowing access to files outside the intended web root directory [1][2].

Exploitation

An attacker can exploit this by sending a crafted HTTP GET request with path traversal sequences (e.g., ../) in the URL. No authentication or special privileges are required; the vulnerability is reachable from the network if the server is exposed [1][2].

Impact

Successful exploitation enables the attacker to read arbitrary files from the server's filesystem, leading to information disclosure of potentially sensitive data such as configuration files, source code, or system files [1][2].

Mitigation

The affected version <= 0.2.10 should be upgraded to a patched release. According to the GitHub Advisory Database, no fixed version is listed; users should consider switching to an alternative tool or applying input validation to block traversal sequences [2]. The CVE is not on the CISA KEV list.
