# Roundcube RCE Exploit (CVE-2025-49113)

A fully functional proof-of-concept exploit for **CVE-2025-49113**

---

## 🧠 Summary

**CVE-2025-49113** is an **The vulnerability is the result of a logic flaw in the application's session parser, which allows insecure deserialization of PHP objects. Authenticated users can exploit this issue to execute arbitrary commands on the server.**

---

## 🔥 Impact

An attacker with **valid credentials** (even low-privileged user accounts) can exploit this flaw to:

- Execute arbitrary system commands.
- Establish reverse shells or deploy persistence.
- Move laterally within the internal network if Roundcube is self-hosted.

---

## 🧩 Vulnerability Details

- **Type:** Insecure Deserialization → Remote Code Execution
- **Component:** PHP backend (mail processing or plugin loading logic)
- **Conditions:** Authenticated session (cookie or login), crafted serialized payload
- **Exploit Primitive:** PHP `unserialize()` with attacker-controlled input and loaded gadgets

---

## ✅ Affected Versions

- **1.5.x:** All versions from `1.5.0` to `1.5.9`
- **1.6.x:** All versions from `1.6.0` to `1.6.10`

> Versions prior to 1.5.0 have not been tested, but are potentially vulnerable if backported plugins or features are present.
