How to Fix CVE-2023-35925

To remediate this vulnerability, upgrade all affected FastAsyncWorldEdit Core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.fastasyncworldedit:FastAsyncWorldEdit-Core fixed: 2.6.3 
<dependency>
    <groupId>com.fastasyncworldedit</groupId>
    <artifactId>FastAsyncWorldEdit-Core</artifactId>
    <version>2.6.3</version>
</dependency>
com.fastasyncworldedit:FastAsyncWorldEdit-Bukkit fixed: 2.6.3 
<dependency>
    <groupId>com.fastasyncworldedit</groupId>
    <artifactId>FastAsyncWorldEdit-Bukkit</artifactId>
    <version>2.6.3</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.fastasyncworldedit

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-35925, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.fastasyncworldedit

Analyze the terminal output to locate any version of FastAsyncWorldEdit Core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.fastasyncworldedit command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Source Advisory Statement

### Coordinated Disclosure Timeline - 10.06.2023: Issue reported to IntellectualSites - 11.06.2023: Issue is acknowledged - 12.06.2023: Issue has been fixed - 22.06.2023: Advisory has been published ### Impacted version range Before 2.6.3 ### Details #### Proof of Concept As a user, do the following: 1. Select position 1 via `//pos1` 2. Select position 2 adding the "Infinity" keyword via `//pos2 Infinity` 3. Execute any further operation. The steps 1 and 2 are interchangeable. #### Impact Such a task has a possibility of bringing the performing server down. #### CVE - CVE-2023-35925 #### Credit This issue was discovered and [reported](https://github.com/IntellectualSites/.github/blob/main/SECURITY.md) by @SuperMonis. ### Solution On June 12, 2023, a patch, https://github.com/IntellectualSites/FastAsyncWorldEdit/pull/2285, has been merged addressing the vulnerability. We strongly recommend users to update their version of FastAsyncWorldEdit to 2.6.3 as soon as possible. ### Workarounds There is no direct mitigation besides updating FastAsyncWorldEdit to a patched version. ### Additional Information Users with access to the `logs/` folder or shell access on their server can try to identify possible abuses of this issue by going through the logs. To sieve through the data, you can use the regex query `\/\/pos[12] Infinity`, then investigate all log entries that return results. ### Disclosure Policy If you discover a security vulnerability within our software, please report the issue according to our [vulnerability disclosure policy](https://github.com/IntellectualSites/.github/blob/main/SECURITY.md).
