CWE-121

Allowed

Stack-based Buffer Overflow

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

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).

Title
TRENDnet TV-IP751WIC alphapd set_time.cgi stack-based overflow
Summary
A security flaw has been discovered in TRENDnet TV-IP751WIC 11.03.03. Affected by this issue is some unknown functionality of the file /cgi-bin/admin/set_time.cgi of the component alphapd. The manipulation of the argument Currenttime results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.

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].
