yaklang/二進制保護繞過

二進制保護繞過操作手冊。用於識別並繞過 ELF 二進制檔案中的 ASLR、PIE、NX/DEP、棧金絲雀、RELRO、FORTIFY_SOURCE、CET 和 MTE 保護,以實現漏洞利用。

二進制保護繞過 是什麼?

此技能是一個全面的二進制保護繞過操作手冊,專為安全研究人員和漏洞利用開發者設計。它針對 ELF 二進制檔案,提供識別和繞過多種常見安全保護機制的實用指南,包括 ASLR(位址空間佈局隨機化)、PIE(位置無關可執行檔)、NX/DEP(不可執行記憶體/資料執行防止)、棧金絲雀、RELRO(僅讀取重定位)、FORTIFY_SOURCE(原始碼強化)、CET(間接分支追蹤)和 MTE(記憶體標籤擴展)。該技能基於詳細的 SKILL.md 文檔,為每個保護機制提供概念解釋、繞過策略、範例代碼和跨平台支援。它支援多種平台,包括 Linux 和類似 Unix 系統,以及常見的漏洞利用工具鏈。通過遵循此手冊,用戶可以系統性地分析二進制保護狀態,並選擇最合適的繞過技術,從而提升漏洞利用的成功率和效率。技能以 YAKLANG 腳本語言為基礎,易於整合到自動化工作流程中。

二進制保護繞過 是做什麼的?

二進制保護繞過操作手冊。用於識別並繞過 ELF 二進制檔案中的 ASLR、PIE、NX/DEP、棧金絲雀、RELRO、FORTIFY_SOURCE、CET 和 MTE 保護,以實現漏洞利用。

介紹

本技能提供一個完整的操作手冊,幫助安全研究人員和開發者識別並繞過現代 ELF 二進制檔案中實施的多種保護機制。通過理解這些保護的工作原理和弱點,您可以有效地繞過它們以實現漏洞利用。

支援的保護機制

  • ASLR:位址空間佈局隨機化
  • PIE:位置無關可執行檔
  • NX/DEP:不可執行記憶體/資料執行防止
  • 棧金絲雀:緩衝區溢位檢測
  • RELRO:僅讀取重定位
  • FORTIFY_SOURCE:原始碼強化
  • CET:間接分支追蹤
  • MTE:記憶體標籤擴展

使用方法

識別保護

checksec --file=<binary>

或使用 YAKLANG:

checkElfProtection("./target_binary")

繞過技術

每種保護機制都有對應的繞過策略。

繞過 ASLR/PIE

使用資訊洩露漏洞來洩露位址:

# 範例:洩露 PIE 基址
leak = leak_address()
base = leak - offset_of_leaked_function

繞過 NX/DEP

使用 ROP(返回導向編程)技術:

ropgadget --binary=<binary>

繞過棧金絲雀

使用格式字串漏洞或堆疊溢出:

// 範例:覆蓋金絲雀值
char canary[8] = leak_canary();
overflow_with_canary(canary);

跨平台支援

本技能支援以下平台:

  • Linux (x86, x86-64, ARM, AArch64)
  • FreeBSD
  • 其他類 Unix 系統

整合

您可以將此技能整合到自動化漏洞利用開發工作流程中:

// YAKLANG 範例
binary = "./vulnerable_binary"
protections = analyzeProtections(binary)

if protections.has("NX") {
    log("偵測到 NX,使用 ROP 繞過")
    ropChain = buildROPChain(binary)
}
