How to Fix CVE-2024-52801

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: 2.6.4 
Upgrade github.com/drakkan/sftpgo/v2 to 2.6.4
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-2024-52801, 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 2.6.4), 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 CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. 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 The OpenID Connect implementation, in the affected SFTPGo versions, allows authenticated users to brute force session cookies and thereby gain access to other users' data, since the cookies are generated predictably using the [xid](https://github.com/rs/xid) library and are therefore unique but not cryptographically secure. ### Patches This issue was fixed in version v2.6.4, where cookies are opaque and cryptographically secure strings. ### References https://github.com/drakkan/sftpgo/commit/f30a9a2095bf90c0661b04fe038e3b7efc788bc6
