Title:Oracle Java SE 输入验证错误漏洞 (CVE-2022-21449)
Description:Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 17.0.2 and 18; Oracle GraalVM Enterprise Edition: 21.3.1 and 22.0.0.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 7.5 (Integrity impacts).

Readme

# CVE-2022-21449

### Overview

This tool allows to perform a quick scan of compiled code archives (.jar, .war etc) in order to check for vulnerability to CVE-2022-21449 by looking for the string indicating the use of ECDSA algorithm. The tool uses Python3 with no additional prerequisites.

##### Usage

```
python cve_2022_21449.py root-folder [-quiet] [-exclude folder1 folder2 ..]
```

or

```
python cve_2022_21449.py root-archive [-quiet] [-exclude folder1 folder2 ..]
```

The tool will scan `root_folder` recursively for `.jar` and `.war` files; in each located archive the tool examines the `.class` files for appearances of `"withECDSA"` string.

With `-quiet` flag, error messages (files not found/ archives failed to open/ password protected archives) are muted.

Folders appearing after `-exclude` (optional) are skipped.

##### Output example

<img src="img/screenshot.PNG" style="zoom:33%;" />

### Bash script

Alternatively, one could use the `cve_2022_21449.sh` Bash script, which is somewhat slower, and requires installing zipgrep tool.

Usage:

```
./cve_2022_21449.sh root-folder
```
