常见的影响
| 范围 | 影响 | 注释 |
|---|---|---|
| ['Access Control', 'Integrity', 'Confidentiality'] | ['Gain Privileges or Assume Identity', 'Modify Application Data', 'Execute Unauthorized Code or Commands'] | An attacker could gain access to sensitive data and possibly execute unauthorized code. |
示例代码
例
In the following code, a JarFile object is created from a downloaded file.
bad Java
JarFile jf = new JarFile(f);
The JAR file that was potentially downloaded from an untrusted source is created without verifying the signature (if present). An alternate constructor that accepts a boolean verify parameter should be used instead.
