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 •

Wire-server is the system server for the wire back-end services. Releases prior to v2022-03-01 are subject to a denial of service attack via a crafted object causing a hash collision. This collision causes the server to spend at least quadratic time parsing it which can lead to a denial of service for a heavily used server. The issue has been fixed in wire-server 2022-03-01 and is already deployed on all Wire managed services. On premise instances of wire-server need to be updated to 2022-03-01, so that their backends are no longer affected. • https://cs-syd.eu/posts/2021-09-11-json-vulnerability https://github.com/wireapp/wire-server/security/advisories/GHSA-phxv-pffh-fq2r • CWE-400: Uncontrolled Resource Consumption •

wire-server provides back end services for Wire, an open source messenger. In versions of wire-server prior to the 2022-01-27 release, it was possible to craft DSA Signatures to bypass SAML SSO and impersonate any Wire user with SAML credentials. In teams with SAML, but without SCIM, it was possible to create new accounts with fake SAML credentials. Under certain conditions that can be established by an attacker, an upstream library for parsing, rendering, signing, and validating SAML XML data was accepting public keys as trusted that were provided by the attacker in the signature. As a consequence, the attacker could login as any user in any Wire team with SAML SSO enabled. • https://github.com/wireapp/wire-server/releases/tag/v2022-01-27 https://github.com/wireapp/wire-server/security/advisories/GHSA-9jg9-9g37-4424 • CWE-347: Improper Verification of Cryptographic Signature •

Wire-server is the backing server for the open source wire secure messaging application. In affected versions it is possible to trigger email address change of a user with only the short-lived session token in the `Authorization` header. As the short-lived token is only meant as means of authentication by the client for less critical requests to the backend, the ability to change the email address with a short-lived token constitutes a privilege escalation attack. Since the attacker can change the password after setting the email address to one that they control, changing the email address can result in an account takeover by the attacker. Short-lived tokens can be requested from the backend by Wire clients using the long lived tokens, after which the long lived tokens can be stored securely, for example on the devices key chain. • https://github.com/wireapp/wire-server/security/advisories/GHSA-9rm2-w6pq-333m • CWE-285: Improper Authorization CWE-613: Insufficient Session Expiration •

wire-server is an open-source back end for Wire, a secure collaboration platform. Before version 2.106.0, the CORS ` Access-Control-Allow-Origin ` header set by `nginz` is set for all subdomains of `.wire.com` (including `wire.com`). This means that if somebody were to find an XSS vector in any of the subdomains, they could use it to talk to the Wire API using the user's Cookie. A patch does not exist, but a workaround does. To make sure that a compromise of one subdomain does not yield access to the cookie of another, one may limit the `Access-Control-Allow-Origin` header to apps that actually require the cookie (account-pages, team-settings and the webapp). wire-server es un back end de código abierto para Wire, una plataforma de colaboración segura. • https://github.com/wireapp/wire-server/security/advisories/GHSA-v7xx-cx8m-g66p • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
