A security flaw has been discovered in opensource-socialnetwork up to 9.11/10.1. This affects the function input of the file actions/administrator/cache/dynamic.php of the component Cache Settings. Performing a manipulation of the argument host/port/username/password/type/status results in code injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The patch is named 40945057cb451f0f35153110bc7e889c094400e1. Applying a patch is the recommended action to fix this issue. The vendor explains: "While we have implemented this patch as a defense-in-depth measure, we emphasize that in Open Source Social Network (OSSN), site administrators are fully trusted users who are intentionally granted broad system authority by design including the native ability to upload custom components/themes containing arbitrary PHP code."
