Stack Buffer Overflow in shttpd 1.34

IdentifiersCVE-2006-5216CWE-121

A stack-based buffer overflow exists in Sergey Lyubka Simple HTTPD (shttpd) version 1.34. The vulnerability is triggered when a remote attacker sends a specially crafted, excessively long URI to the server, resulting in a buffer overflow on the stack. This can allow for the execution of arbitrary code within the context of the shttpd process.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows remote attackers to execute arbitrary code on the target system with the privileges of the shttpd process, potentially leading to full system compromise.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the shttpd service to trusted networks only, use network-level filtering to block untrusted sources, and consider running shttpd with reduced privileges and in a chroot jail to limit the impact of exploitation.

Remediation

Patch, then assume compromise.

Upgrade to a version of shttpd where this vulnerability is patched. If no patch is available, consider replacing shttpd with a maintained and secure HTTP server.

shttpd_post.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (modules/exploits/windows/http/shttpd_post.rb) that exploits a stack buffer overflow vulnerability in SHTTPD versions 1.34 and earlier (CVE-2006-5216). The exploit targets Windows systems running the vulnerable SHTTPD web server. The module crafts a specially encoded HTTP POST request with a malicious URI to overflow a stack buffer, allowing arbitrary code execution with the privileges of the SHTTPD process. The exploit supports multiple Windows targets with specific return addresses for each version and locale. The payload is user-selectable via the Metasploit framework and is injected into the overflowed buffer. The module requires the target's HTTP service to be accessible (default TCP port 80). The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file.
