### Summary The application allows users to upload files with scripts in the filename parameter. As a result, a malicious user can upload a script file to the system. When users in the application use the "Diff or Compare" functionality, they are affected by a Stored Cross-Site Scripting vulnerability. ### Details I found a Stored Cross-Site Scripting vulnerability in the "Diff or Compare" functionality. This issue occurs because the upload functionality allows users to upload files with special characters such as <, >, /, and " in the filename. This vulnerability can be mitigated by restricting file uploads to filenames containing only whitelisted characters, such as A-Z, 0-9, and specific special characters permitted by business requirements, like - or _ . ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ 1. On MobSF version 4.2.8, I clicked on "Unload & Analyze" button. . ### Patches Synapse 1.120.1 addresses the issue by restricting thumbnail generation to images in the following widely used formats: PNG, JPEG, GIF, and WebP. ### Workarounds - Ensure any image codecs and helper programs, such as Ghostscript, are patched against security vulnerabilities. - Uninst...
### Impact Synapse versions before 1.120.1 fail to properly validate invites received over federation. This vulnerability allows a malicious server to send a specially crafted invite that disrupts the invited user's `/sync` functionality. ### Patches Synapse 1.120.1 rejects such invalid invites received over federation and restores the ability to sync for affected users. ### Workarounds Server administrators can disable federation from untrusted servers. ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:[email protected]).
Consumers are getting caught in a web of scams facilitated by online ads often originating from the same perpetrators.
### Impact In Synapse before 1.120.1, `multipart/form-data` requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. ### Patches Synapse 1.120.1 resolves the issue by denying requests with unsupported `multipart/form-data` content type. ### Workarounds Limiting request sizes or blocking the `multipart/form-data` content type before the requests reach Synapse, for example in a reverse proxy, alleviates the issue. Another approach that mitigates the attack is to use a low `max_upload_size` in Synapse. ### References - https://github.com/twisted/twisted/issues/4688#issuecomment-1167705518 - https://github.com/twisted/twisted/issues/4688#issuecomment-2385711609 ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:[email protected]).
