CVSS: 5.4EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28635 – Defining resource name as integer in vantage6 may give unintended access
https://notcve.org/view.php?id=CVE-2023-28635
vantage6 is privacy preserving federated learning infrastructure. Prior to version 4.0.0, malicious users may try to get access to resources they are not allowed to see, by creating resources with integers as names. One example where this is a risk, is when users define which users are allowed to run algorithms on their node. This may be defined by username or user id. Now, for example, if user id 13 is allowed to run tasks, and an attacker creates a username with username '13', they would be wrongly allowed to run an algorithm. • https://github.com/vantage6/vantage6/blob/0682c4288f43fee5bcc72dc448cdd99bd7e57f76/docs/release_notes.rst#400 https://github.com/vantage6/vantage6/pull/744 https://github.com/vantage6/vantage6/security/advisories/GHSA-7x94-6g2m-3hp2 • CWE-863: Incorrect Authorization •
CVSS: 7.2EPSS: 0%CPEs: 1EXPL: 1CVE-2023-23930 – vantage6's Pickle serialization is insecure
https://notcve.org/view.php?id=CVE-2023-23930
vantage6 is privacy preserving federated learning infrastructure. Versions prior to 4.0.0 use pickle, which has known security issue, as a default serialization module but that has known security issues. All users of vantage6 that post tasks with the default serialization are affected. Version 4.0.0 contains a patch. Users may specify JSON serialization as a workaround. vantage6 es una infraestructura de aprendizaje federada que preserva la privacidad. • https://github.com/vantage6/vantage6/blob/0682c4288f43fee5bcc72dc448cdd99bd7e57f76/docs/release_notes.rst#400 https://github.com/vantage6/vantage6/commit/e62f03bacf2247bd59eed217e2e7338c3a01a5f0 https://github.com/vantage6/vantage6/security/advisories/GHSA-5m22-cfq9-86x6 https://medium.com/ochrona/python-pickle-is-notoriously-insecure-d6651f1974c9 • CWE-502: Deserialization of Untrusted Data •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-22738 – Improper Preservation of Permissions in vantage6
https://notcve.org/view.php?id=CVE-2023-22738
vantage6 is a privacy preserving federated learning infrastructure for secure insight exchange. Assigning existing users to a different organizations is currently possible. It may lead to unintended access: if a user from organization A is accidentally assigned to organization B, they will retain their permissions and therefore might be able to access stuff they should not be allowed to access. This issue is patched in version 3.8.0. • https://github.com/vantage6/vantage6/commit/798aca1de142a4eca175ef51112e2235642f4f24 https://github.com/vantage6/vantage6/security/advisories/GHSA-vvjv-97j8-94xh • CWE-281: Improper Preservation of Permissions •
