Authentication Bypass by Spoofing

YesWiki before 4.6.7 contains an authentication bypass vulnerability in the ActivityPub inbox that fails to bind the verified HTTP signature signer to the activity actor. Unauthenticated attackers with any ActivityPub keypair can send signed Delete or Update activities referencing a mirrored entry's sourceUrl to delete or overwrite other actors' federated entries.Show less

OpenSave before 2.4.0-beta.1 fails to validate sender identity in WAN relay requests, allowing unpaired room members to impersonate paired devices by spoofing the RelayMessage From field. Attackers who know the room code can join, read paired peer identifiers from announcements, and send forged requests to access protected sync routes including save data, snapshots, and file operations.Show less

Apache WSS4J remembers the Nonce of each UsernameToken it accepts, so a captured token cannot be reused. It stored the Nonce as raw base64 text, but authentication decodes that text and uses the bytes.The same bytes can be written as base64 in several ways. An attacker who captured an authenticated request could re-send it with a space added to the Nonce: the password digest still verified, but the token no longer matched the remembered one, so the replay was accepted. Since a UsernameToken does not cover the message body, the captured token could then be reused on requests of the attacker's choosing until it expired. Affects deployments with a nonce replay cache configured, as Apache CXF has by default, and only tokens using a password digest. The cache is now keyed on the decoded Nonce. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.Show less

A vulnerability was detected in Trusted Domain Project OpenDMARC up to 1.4.2. Affected is the function opendmarc_policy_query_dmarc of the component Multi-Record Set Handler. The manipulation results in authentication bypass by spoofing. The attack can be executed remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

A cross-tenant authorization issue was discovered in SUSE Rancher Fleet. During agent-initiated cluster registration, cluster labels supplied by the registering agent, including labels in the reserved management.cattle.io/ namespace such as the cluster display name label, were applied to the resulting upstream Cluster object. Because Fleet resolves GitRepo and Bundle targets from those cluster labels, a party able to register a cluster into a Fleet workspace namespace shared with other tenants could cause its own cluster to satisfy targeting rules that administrators intended for a different cluster. This affects SUSE Rancher Fleet 0.16 before 0.16.1, 0.15 before 0.15.6, 0.14 before 0.14.10, 0.13 before 0.13.15, 0.12 before 0.12.19 and older versions.Show less

Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access controls.Show less

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when Zammad checks the digital signature on an incoming S/MIME-signed email, it does not verify that the signing certificate is genuinely trusted, it only checks whether a certificate with a matching name is already stored in the system. An attacker can create their own certificate using the name of a real, previously trusted sender and use it to send a forged email. Zammad will display that email with the same "validly signed" indicator as a genuine message from the real sender, even though the attacker never had access to that sender's actual certificate or private key. This issue is fixed in version 7.1.2.Show less

An authorization bypass was found in the Ansible Automation Platform (AAP) gateway. The gateway API allows an authenticated administrator to create a new service key for the Controller service cluster. Because service-key creation is not restricted to the installer-provisioned provisioning path, an administrator-issued key is cryptographically indistinguishable from a legitimate one and can be used to forge a service-authentication token that impersonates the Controller service. Combined with the gateway OIDC workload-identity endpoint (enabled via FEATURE_OIDC_WORKLOAD_IDENTITY_ENABLED), the attacker can drive the gateway to sign Workload Identity Tokens (WITs) for arbitrary Controller workloads. A downstream resource server such as HashiCorp Vault that trusts the gateway OIDC key will accept the forged WIT and return the AAP credentials bound to that workload, disclosing secrets beyond the attacker's authorization boundary.Show less

The Premium Packages WordPress plugin before 7.2.1 does not verify PayPal's webhook signature before processing payment and subscription notifications, allowing unauthenticated attackers to forge payment confirmations and subscription-cancellation events against any order whose transaction id they know.Show less

OpenEye Apex Network Video Recorder (NVR) firmware 3.2.9.376 trusts an X-Forwarded-For header supplied by an arbitrary client when determining the request source address. An unauthenticated remote attacker can spoof a loopback address to bypass local-connection-only security controls exposed on the affected non-TLS web interfaces and disclose configuration information. The underlying design has been present since at least firmware 2.2.3.4. Upgrade to version 3.5.4.Show less

pH7Software pH7Builder (pH7 Social Dating CMS) through 18.2.0 resolves the client IP address in _protected/framework/Ip/Ip.class.php from the HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR headers without verifying the request comes from a trusted proxy. Because the admin login attempt counter and lockout are keyed on this value, a remote unauthenticated attacker bypasses IP-based throttling by sending a different X-Forwarded-For value per requestShow less

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Server's UserModel.ssoLogin() returns an existing account matched by an IdP-asserted email without checking the account's is_external flag. In deployments using mixed local and SAML authentication, an attacker whose IdP session can assert a local user's email can pass POST /api/saml, receive a session for that local account, and access or modify the victim's notes, files, and settings without knowing the local password. This issue is fixed in version 3.7.2.Show less

Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. Prior to 0.25.6, copy_server_request in warpgate-protocol-http/src/proxy.rs forwards a client-supplied x-warpgate-username header before inject_own_headers appends the authenticated username. Because the request builder preserves repeated values, a proxied backend that trusts the first x-warpgate-username value can authorize an authenticated attacker as another user. The same forwarding policy also accepts the reserved x-warpgate-authentication-type header, and warpgate-common/src/http_headers.rs does not exclude either reserved identity header. This issue is fixed in version 0.25.6.Show less
