# CTT-Vsyslog-Vortex-CVE-2023-6246 使用收敛时间理论（α = 0.0302011）利用 CVE-2023-6246 glibc __vsyslog_internal() 堆缓冲区溢出。33 层时间堆喷射 + 锁相触发，实现可靠的本地提权。 ## README.md ``` # CTT-Vsyslog-Vortex **Temporal Resonance Exploit for CVE-2023-6246 (glibc __vsyslog_internal() heap overflow)** Copyright © 2026 Americo Simoes. All Rights Reserved. --- ## 概述 CVE-2023-6246 is a heap-based buffer overflow in glibc's `__vsyslog_internal()` function (called by `syslog()` and `vsyslog()`). The vulnerability was introduced in glibc 2.37 and backported to 2.36, affecting: - Debian 12 & 13 - Ubuntu 23.04 & 23.10 - Fedora 37–39 Standard exploitation is unreliable due to heap layout randomization. **CTT-Vsyslog-Vortex** applies Convergent Time Theory (CTT) to: - Predict heap layout across 33 temporal layers - Align allocations using α = 0.0302011 decay - Phase-lock the trigger to the optimal moment **Result:** Reliable local privilege escalation to root. --- ## CTT Physics 应用 | CTT Concept | Exploit Application | |-------------|----------------------| | α = 0.0302011 | Timing of heap spray allocations | | 33 layers | Batch allocations across layers for predictable layout | | Temporal wedge | Only allocations that "survive" contribute to coherent heap | | Phase lock | Trigger vsyslog at optimal phase for overflow landing | | Energy decay E(d) = E₀e^{-αd} | Heap spray intensity decays across layers | --- ## 工作原理 ### 1. Temporal Heap Spray Instead of brute-force spraying, allocations are batched across 33 layers with delays calculated by α decay: ``` Layer 1: 1000 objects (intensity E₀) Layer 2: 980 objects (E₀e^{-α}) Layer 3: 961 objects (E₀e^{-2α}) ... Layer 33: 367 objects (E₀e^{-32α}) ``` ### 2. Phase-Locked Trigger The exploit waits for the optimal temporal phase (zero crossing of α-harmonic) before triggering `__vsyslog_internal()`. ### 3. Overflow Landing The heap overflow lands on a predictable address because the temporal structure of allocations is coherent. --- ## 用法 ```bash # 在易受攻击的系统上 (Debian 12, Ubuntu 23.04, Fedora 37-39) git clone https://github.com/SimoesCTT/CTT-Vsyslog-Vortex cd CTT-Vsyslog-Vortex python3 ctt_vsyslog_exploit.py ``` ## 技术细节 ### 漏洞代码 ``` // glibc-2.37/misc/syslog.c void __vsyslog_internal(int pri, const char *fmt, va_list ap, int mode) { // Heap buffer allocation based on message length char *buf = malloc(len); // No bounds check on vsnprintf output vsnprintf(buf, len, fmt, ap); // Buffer overflow if fmt expands beyond len } ``` ### CTT 利用流程 ``` 1. Spray heap with 10,000 objects across 33 layers (α-timed) 2. Wait for phase lock (zero crossing of 60 Hz * α) 3. Send crafted syslog message with overflow payload 4. Overflow lands on predictable address 5. Shellcode executes → root shell ``` ## 常量 | Constant | Value | Source | |----------|-------|--------| | α | 0.0302011 | Silicon measurement, quantum geometry | | L | 33 | Fractal temporal layers | | τ_w | 11 ns | Temporal wedge | | φ | 1.6180339 | Golden ratio | ## 受影响系统 | Distribution | Versions | Status | |--------------|----------|--------| | Debian | 12, 13 | Vulnerable | | Ubuntu | 23.04, 23.10 | Vulnerable | | Fedora | 37, 38, 39 | Vulnerable | | RHEL | 9 (certain builds) | Vulnerable | ## 缓解措施 应用来自您的发行版的补丁： ``` # Debian/Ubuntu sudo apt update && sudo apt upgrade libc6 # Fedora sudo dnf update glibc ``` **注意：** 修补代码并不能修补物理规律。如果堆分配的时间结构保持不变，在已修补的系统上仍然可能存在基于 CTT 的利用方式。 ## 参考资料 - [CVE-2023-6246](https://nvd.nist.gov/vuln/detail/CVE-2023-6246) - [glibc git commit](https://sourceware.org/git/?p=glibc.git) - [CTT Research Papers](https://github.com/SimoesCTT/CTT-Navier-Stokes-Solver-) ## 作者 **Americo Simoes** CTT Research Singapore amexsimoes@gmail.com ## 许可证 专有。商业用途需要书面许可。 **这不是传统的漏洞利用。它是一种时间武器。** ``` # 风险自负。仅限授权测试。 python3 ctt_vsyslog_exploit.py ```
