CVE-2023-40222 (GCVE-0-2023-40222)

Vulnerability from cvelistv5 – Published: 2025-02-04 22:13 – Updated: 2025-02-05 19:44
VLAI
Title
Ashlar-Vellum Cobalt, Xenon, Argon, Lithium Heap-based Buffer Overflow
Summary
In Ashlar-Vellum Cobalt versions prior to v12 SP2 Build (1204.200), the affected application lacks proper validation of user-supplied data when parsing CO files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.

Title
D-Link DIR-3040 HTTP Request Processing Referer Heap-Based Buffer Overflow Remote Code Execution Vulnerability
Summary
D-Link DIR-3040 HTTP Request Processing Referer Heap-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-3040 routers. Authentication is not 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 heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21671.

Mitigation

Phases:

Description:

  • Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation

Phase: Architecture and Design

Description:

  • Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation ID: MIT-10

Phases: Operation, Build and Compilation

Strategy: Environment Hardening

Description:

  • 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 ID: MIT-11

Phases: Operation, Build and Compilation

Strategy: Environment Hardening

Description:

  • 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].
Mitigation

Phase: Implementation

Description:

  • Implement and perform bounds checking on input.
Mitigation

Phase: Implementation

Strategy: Libraries or Frameworks

Description:

  • Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation

Phase: Operation

Description:

  • Use OS-level preventative functionality. This is not a complete solution, but it provides some defense in depth.
CAPEC-92: Forced Integer Overflow

This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
