CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-31122 – Wire-server vulnerable to Token Recipient Confusion resulting in account impersonation, deletion or malicious account creation
https://notcve.org/view.php?id=CVE-2022-31122
Wire is an encrypted communication and collaboration platform. Versions prior to 2022-07-12/Chart 4.19.0 are subject to Token Recipient Confusion. If an attacker has certain details of SAML IdP metadata, and configures their own SAML on the same backend, the attacker can delete all SAML authenticated accounts of a targeted team, Authenticate as a user of the attacked team and create arbitrary accounts in the context of the team if it is not managed by SCIM. This issue is fixed in wire-server 2022-07-12 and is already deployed on all Wire managed services. On-premise instances of wire-server need to be updated to 2022-07-12/Chart 4.19.0, so that their backends are no longer affected. • https://github.com/wireapp/wire-server/security/advisories/GHSA-gq27-gmgq-fmxw • CWE-287: Improper Authentication CWE-1270: Generation of Incorrect Security Tokens •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-21396 – Bulk list client endpoint exposes too much metadata about a client
https://notcve.org/view.php?id=CVE-2021-21396
wire-server is an open-source back end for Wire, a secure collaboration platform. In wire-server from version 2021-02-16 and before version 2021-03-02, the client metadata of all users was exposed in the `GET /users/list-clients` endpoint. The endpoint could be used by any logged in user who could request client details of any other user (no connection required) as far as they can find their User ID. The exposed metadata included id, class, type, location, time, and cookie. A user on a Wire backend could use this endpoint to find registration time and location for each device for a given list of users. • https://github.com/wireapp/wire-server/commit/7ba2bf4140282557cf215e0b2c354d4d08cd3421 https://github.com/wireapp/wire-server/releases/tag/v2021-03-02 https://github.com/wireapp/wire-server/security/advisories/GHSA-qx8q-rhq2-rg4j • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
