When a Windows stack overflow gives you ~250 bytes of crash-buffer space but a useful Meterpreter payload is 400 bytes, the answer is an egghunter. This walkthrough takes Savant Web Server 3.1 from initial crash to NT-level shell: partial overwrite to defeat the savant.exe null-byte module base, POP EAX RET gadget, a 7-byte conditional jump that exploits pre-zeroed memory, two independent buffers (URL path HTTP body), then both classic egghunters — syscall-based on Windows 10 (with the NEG trick to encode 0x1C8 null-free) and the OS-agnostic SEH-based variant with a custom dispatcher handler. core-jmp.org/2026/06/egghunt… #BadCharacters #bufferoverflow #Egghunter #gadgets #HeapStaging #INT0x2E #KeystoneEngine #Metasploit #Meterpreter #NtAccessCheckAndAuditAlarm #NullFreeShellcode #PartialOverwrite #POPEAXRET #ROP #SavantWebServer #SCASD #SEHEgghunter #shellcode #StackBufferOverflow #StackOverflow #w00tw00tEgg #WinDBG #WindowsExploitDevelopment #x86

الصورة ال تحت دي من claude مطلعلي logout idor مش شغاله وال id اصلا uuid بس مطلعها critical 😂 هل دة معناه انو ملهوش لازمة طبعا لا بس للي بيهول الامور يعني ال AI هيساعدك ف شغلك بس لو انت فيه حاجة مش فاهمها حتي لو ال AI طلعهالك انت مش هتعرف تفالديتها ومش هتعرف تكملها للاخر يعني لازم تكون فاهم مجالك اوي اوي عشان تعرف تشتغل وتعرف تفالديت الحاجة ال بيطلعهالك غير كدة هتبلغ الحاجة ال بتطلعلك علي كدة وهتتقفلك N/A ف نصيحة سيبك من اي كلام داير انت لو مش فاهم مجالك كويس ولا AI ولا غيرة هينفعك انت دلوقتي لو مش فاهم مثلا في ال Memory corruption attacks وطلعلك Bufferoverflow علي سبيل المثال انت مش هتعرف تعمل بيها حاجة، نفس الكلام لو مديلو كود مثلا ل asp application وطلعلك insecure deserialization والله م هتعرف تفالديتها وتكملها للاخر لو انت مش فاهم كويس ف ال AI حاجة كويسة وبتساعدك ف شغلك اللي انت فاهمة!! انما طول م انت مش فاهم لو جبت حتي حد يشتغل مكانك مش هتعرف تعمل حاجة 😂 الله يرزقنا ويوفقنا جميعا

Bir bardağa kapasitesinden fazla su doldurursanız ne olur? Taşar ve her yer ıslanır. Peki, ya bu "taşma" bir bilgisayarın hafızasında yaşanırsa? Buffer Overflow, siber dünyanın en eski ama en ölümcül saldırılarından biridir! Bir program, kendisi için ayrılan bellek alanına (Buffer) kapasitesinden fazla veri kabul ettiğinde, taşan veriler komşu bellek hücrelerini istila eder. ✅ Stack Smashing: Saldırgan, taşan verinin sonuna kendi zararlı kodunu ekler. ✅ Komuta Kontrol: Taşma sırasında işlemcinin "bir sonraki adım" komutu saldırganın koduna yönlendirilir. ✅ Tam Yetki: Saniyeler içinde sıradan bir kullanıcıdan, sistemi yöneten bir "Root" kullanıcısına dönüşebilirsiniz. Güvenli kod yazılmayan her sistem, bu taşmaya mahkumdur. Unutmayın; bir bardak su sadece masayı ıslatır, bir "buffer overflow" tüm kaleyi içeriden fetheder! #BufferOverflow #CyberSecurity #SiberGüvenlik #Exploit #Hacking #Infosec #CodeSafety
