Stack-based Buffer Overflow

memory HIGH

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.

How It Works

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold. The stack stores local variables, function parameters, and critical control information including the return address that tells the CPU where to resume execution after a function completes. When an attacker overflows a buffer, they can overwrite adjacent memory, including this return address.

The classic exploitation path involves carefully crafting input to overwrite the return address with a pointer to attacker-controlled code. Historically, attackers would inject shellcode directly into the overflowed buffer, then redirect execution to it. Modern defenses like Data Execution Prevention (DEP/NX) mark the stack as non-executable, forcing attackers to use Return-Oriented Programming (ROP) instead—chaining together existing code snippets ("gadgets") to perform malicious operations without injecting new code.

Address Space Layout Randomization (ASLR) randomizes memory addresses to make exploitation harder, but attackers can defeat it through information disclosure vulnerabilities that leak memory addresses. Stack canaries—random values placed between buffers and control data—can detect overwrites, but may be bypassed through brute-force attacks or by carefully avoiding them in partial overwrites.

Impact

  • Arbitrary code execution at the privilege level of the vulnerable process
  • Complete system compromise if the vulnerable process runs with elevated privileges (root/SYSTEM)
  • Memory corruption leading to crashes and denial of service
  • Bypass of authentication mechanisms by redirecting execution flow around security checks
  • Data theft or modification through code injection that accesses sensitive memory regions

Real-World Examples

The Morris Worm (1988) exploited a stack overflow in the Unix fingerd daemon, becoming one of the first major internet worms. The Code Red worm (2001) leveraged a stack overflow in Microsoft IIS (CVE-2001-0500) to compromise hundreds of thousands of web servers, demonstrating the massive scale of automated exploitation.

More recently, EternalBlue exploited stack corruption in Windows SMB (CVE-2017-0144), enabling the WannaCry and NotPetya ransomware outbreaks that caused billions in damage. The Heartbleed bug (CVE-2014-0160), while technically a heap-based read overflow, demonstrated how buffer handling errors remain prevalent even in security-critical software like OpenSSL.

Mitigation

  • Stack canaries (compile with -fstack-protector-all or equivalent) to detect overwrites before return
  • Address Space Layout Randomization (ASLR) to randomize memory locations
  • DEP/NX bit enforcement to prevent code execution from stack memory
  • Memory-safe string functions (use strncpy, snprintf, strlcpy instead of strcpy, sprintf, gets)
  • Compiler hardening flags (-D_FORTIFY_SOURCE=2, control-flow integrity)
  • Input validation with strict bounds checking on all externally-supplied data
  • Memory-safe languages (Rust, Go) for new development to eliminate the vulnerability class entirely

iccDEV versions prior to 2.3.1.2 are vulnerable to stack overflow through malformed XML calculator macro expansion, allowing local attackers to trigger a denial of service condition. Public exploit code exists for this vulnerability, which affects ICC color profile manipulation tools used in Stack Overflow and Iccdev products. A patch is available in version 2.3.1.2 and should be applied promptly to mitigate exploitation risk.

Stack-based buffer overflow in the ONVIF SOAP XML parser of TP-Link Tapo C200 v3 (firmware ≤1.4.1) and C520WS v2.6 cameras enables unauthenticated remote code execution from adjacent networks. Attackers can send crafted SOAP requests with oversized namespace prefixes to trigger memory corruption and achieve full device compromise with elevated privileges. EPSS probability and KEV status indicate no public exploit identified at time of analysis, though the vulnerability affects widely deployed consumer IoT cameras with network exposure.

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'SetUserPassword()' function, the 'newPassword' parameter is directly embedded in a shell command string using 'sprintf()' without any sanitisation or validation, and then executed using 'system()'. This allows an attacker to inject arbitrary shell commands that will be executed with the same privileges as the application.

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'ShowMeterPasswords()' function, there is an unlimited user input that is copied to a fixed-size buffer via 'sprintf()'. The 'GetParameter(meter)' function retrieves the user input, which is directly incorporated into a buffer without size validation. An attacker can provide an excessively large input for the 'meter' parameter.

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The vulnerability is found in the 'AddEvent()' function when copying the user-controlled username input to a fixed-size buffer (48 bytes) without boundary checking. This can lead to memory corruption, resulting in possible remote code execution.

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The 'ShowDownload()' function uses “sprintf()” to format a string that includes the user-controlled input of 'GetParameter(meter)' in the fixed-size buffer 'acStack_4c' (64 bytes) without checking the length. An attacker can provide an excessively long value for the 'meter' parameter that exceeds the 64-byte buffer size.

Stack-based buffer overflow vulnerability in CircutorSGE-PLC1000/SGE-PLC50 v9.0.2. The 'SetLan' function is invoked when a new configuration is applied. This new configuration function is activated by a management web request, which can be invoked by a user when making changes to the 'index.cgi' web application. The parameters are not being sanitised, which could lead to command injection.
