CWE-127 缓冲区下溢读取

Buffer Under-read

结构: Simple

Abstraction: Variant

状态: Draft

被利用可能性: unkown

基本描述

The software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations prior to the targeted buffer.

扩展描述

This typically occurs when the pointer or its index is decremented to a position before the buffer, when pointer arithmetic results in a position before the beginning of the valid memory location, or when a negative index is used. This may result in exposure of sensitive information or possibly a crash.

常见的影响

范围 影响 注释
Confidentiality Read Memory
Confidentiality Bypass Protection Mechanism By reading out-of-bounds memory, an attacker might be able to get secret values, such as memory addresses, which can be bypass protection mechanisms such as ASLR in order to improve the reliability and likelihood of exploiting a separate weakness to achieve code execution instead of just denial of service.
