CVE-2023-25610 is a critical heap buffer underflow in the HTTP/HTTPS GUI administrative interface of Fortinet FortiOS, FortiProxy, FortiOS-6K7K, FortiManager, FortiAnalyzer, FortiWeb, FortiSwitchManager, and FortiSwitch. Specially crafted requests can trigger the underwrite before authentication, potentially resulting in arbitrary code execution on affected devices or denial of service against the administrative GUI. Certain FortiGate and FortiWiFi hardware models are affected only by the denial-of-service condition.

This repository contains a Python exploit script (CVE-2023-25610.py) targeting CVE-2023-25610, a heap underflow vulnerability in the FortiOS management interface (Fortinet 6.x). The exploit leverages a crafted POST request over TLSv1.3 to the /login endpoint of the target device, using a ROP chain to achieve remote code execution. Upon successful exploitation, the script establishes a reverse shell from the target device to the attacker's machine on TCP port 31226, executing arbitrary commands as specified by the user. The repository includes only one code file (the exploit), with the rest being IDE configuration files and a README.md that provides usage instructions and context. No detection or scanning scripts are present; the repository is focused solely on exploitation.

A critical heap buffer underflow in the administrative interface of multiple Fortinet products that may allow remote unauthenticated code execution and/or denial of service via crafted requests.
Critical unauthenticated remote-code-execution vulnerability caused by a buffer underwrite in the HTTP/HTTPS administrative interface of FortiOS and FortiProxy. Specially crafted requests can enable arbitrary remote code execution on affected FortiOS/FortiProxy devices; certain additional Fortinet products may be vulnerable to denial of service only.
A heap/buffer underflow vulnerability in the administrative interface of FortiOS and FortiProxy that may allow remote unauthenticated attackers to execute arbitrary code on the device and/or cause denial of service on the GUI via crafted requests.
