CWE-125 跨界内存读 类漏洞列表 3495

CWE-125 跨界内存读 类弱点 3495 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-125 越界读取属于内存安全漏洞,指程序访问了缓冲区边界之外的内存区域。攻击者利用此缺陷可读取敏感数据或引发信息泄露,甚至通过特定构造触发逻辑错误以辅助后续攻击。开发者应严格实施边界检查,确保索引在有效范围内,并使用支持自动边界检测的高级语言或静态分析工具,从源头杜绝非法内存访问。

MITRE CWE 官方描述
CWE:CWE-125 Out-of-bounds Read 英文:The product reads data past the end, or before the beginning, of the intended buffer. 中文:该产品在预期缓冲区(buffer)的末尾之后或开头之前读取数据。
常见影响 (4)
Confidentiality Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other Varies by Context
The read operation could produce other undefined or unexpected results.
缓解措施 (2)
Implementation Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all potentially relevant properties, including length, type of input, the full range…
Architecture and Design Use a language that provides appropriate memory abstractions.
代码示例 (2)
In the following code, the method retrieves a value from an array at a specific array index location that is given as an input parameter to the method
int getValueFromArray(int *array, int len, int index) { int value; // check that the array index is less than the maximum // length of the array if (index < len) { // get the value at the specified index of the array value = array[index]; } // if array index is invalid then output error message // and return value indicating error else { printf("Value is: %d\n", array[index]); value = -1; } return value; }
Bad · C
... // check that the array index is within the correct // range of values for the array if (index >= 0 && index < len) { ...
Good · C
In the following C/C++ example the method processMessageFromSocket() will get a message from a socket, placed into a buffer, and will parse the contents of the buffer into a structure that contains the message length and the message body. A for loop is used to copy the message body into a local character string which will be passed to another method for processing.
int processMessageFromSocket(int socket) { int success; char buffer[BUFFER_SIZE]; char message[MESSAGE_SIZE]; // get message from socket and store into buffer //Ignoring possibliity that buffer > BUFFER_SIZE if (getMessage(socket, buffer, BUFFER_SIZE) > 0) { // place contents of the buffer into message structure ExMessage *msg = recastBuffer(buffer); // copy message body into string for processing int index; for (index = 0; index < msg->msgLength; index++) { message[index] = msg->msgBody[index]; } message[index] = '\0'; // process message success = processMessage(message); } return success; }
