CWE-121
AllowedStack-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).
5237 vulnerabilities reference this CWE, most recent first.
GHSA-3GWW-3727-4334
Vulnerability from github – Published: 2024-03-27 15:30 – Updated: 2024-03-27 15:30A vulnerability was found in Tenda F1203 2.0.1.6. It has been rated as critical. Affected by this issue is the function formQuickIndex of the file /goform/QuickIndex. The manipulation of the argument PPPOEPassword leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-258146 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Authentication is required to exploit this vulnerability.
The specific flaw exists within the prog.cgi binary, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. The issue results from the lack of proper validation of a user-supplied string before copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21592.

Mitigation MIT-10
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
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Implement and perform bounds checking on input.
Mitigation
Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.
Mitigation MIT-11
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].
