Common Weakness Enumeration

CWE-121

Allowed

Stack-based Buffer Overflow

Abstraction: Variant · Status: Draft

A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

5236 vulnerabilities reference this CWE, most recent first.

Details

10-Strike Network Inventory Explorer 8.54 contains a stack-based buffer overflow vulnerability in the registration key input field that allows local attackers to execute arbitrary code by triggering a structured exception handler overwrite. Attackers can craft a malicious registration key string with 4188 bytes of padding followed by SEH chain values and shellcode, then paste it into the registration dialog to achieve code execution with application privileges.

GHSA-337W-H8W7-M899

Vulnerability from github – Published: 2026-01-26 21:30 – Updated: 2026-05-12 15:31
VLAI
Details

A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.

GHSA-34F4-HGHJ-WW8R

Vulnerability from github – Published: 2024-11-28 00:39 – Updated: 2024-11-28 00:39
VLAI
Details

Fuji Electric Tellus Lite V-Simulator 5 V8 File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Tellus Lite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of V8 files in the V-Simulator 5 component. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24768.

Vulnerability from github – Published: 2023-01-12 00:30 – Updated: 2023-01-20 21:30
VLAI
Details

Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub running firmware version 1012. Specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. In cmd s_init_event, at 0x9d01ea88, the value for the s_event_offset key is copied using strcpy to the buffer at $sp+0x2b0.This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.

Mitigation MIT-10
Operation Build and Compilation

Strategy: Environment Hardening

  • Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
  • D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation
Architecture and Design

Use an abstraction library to abstract away risky APIs. Not a complete solution.

Mitigation
Implementation

Implement and perform bounds checking on input.

Mitigation
Implementation

Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.

Mitigation MIT-11
Operation Build and Compilation

Strategy: Environment Hardening

  • Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
  • Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
  • For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
