How to Fix CVE-2024-52309

To remediate this vulnerability, upgrade all affected Github.com/drakkan/sftpgo/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/drakkan/sftpgo/v2 fixed: 2.6.3 
Upgrade github.com/drakkan/sftpgo/v2 to 2.6.3
sftpgo fixed: 2.6.3 
Upgrade sftpgo to 2.6.3
Verify Direct and Transitive Dependencies

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

inspect dependencies for github.com/drakkan/sftpgo/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-52309, inspect your project dependencies for Github.com/drakkan/sftpgo/v2:

inspect dependencies for github.com/drakkan/sftpgo/v2

Analyze the terminal output to locate any version of Github.com/drakkan/sftpgo/v2 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: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Github.com/drakkan/sftpgo/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact One powerful feature of SFTPGo is the ability to have the EventManager execute scripts or run applications in response to certain events. This feature is very common in all software similar to SFTPGo and is generally unrestricted. However, any SFTPGo administrator with permission to run a script has access to the underlying OS/container with the same permissions as the user running SFTPGo, so they can access the database and server configurations. This is unexpected for some SFTPGo administrators who think that there is a clear distinction between accessing the system shell and accessing the SFTPGo WebAdmin UI. ### Patches To avoid this confusion, running system commands is now disabled by default, and an allow list has been added so that system administrators configuring SFTPGo must explicitly define which commands are allowed to be configured from the WebAdmin UI. https://github.com/drakkan/sftpgo/commit/88b1850b5806eee81150873d4e565144b21021fb https://github.com/drakkan/sftpgo/commit/b524da11e9466d05fe03304713ee1c61bb276ec4 ### Workarounds Allow EventManager to be used only by SFTPGo administrators who also have shell access.
