Title
inets, httpd: Authentication Bypass via Directory Namespace Collapse in httpd mod_auth
Summary
The mod_auth module in OTP's inets httpd server, when configured with dets or mnesia authentication backends and multiple directory configuration blocks, collapses all directory blocks into a single shared user/group namespace. A user added to one protected directory is accepted as valid for all other protected directories on the same server instance.
This issue affects OTP from OTP 17.0 before OTP 27.3.4.17, from OTP 28.0 before OTP 28.5.0.6, and from OTP 29.0 before OTP 29.0.6, corresponding to inets from 5.10 before 9.3.2.7, from 9.4 before 9.6.2.3, and from 9.7 before 9.7.2. Whether OTP before OTP 17.0, corresponding to inets before 5.10, is affected is unknown.

SiYuan before v3.7.4 contains an incorrect authorization vulnerability in eight publish-mode reader-facing endpoints that filter results using the visibility list instead of the disabled list. Anonymous visitors can discover and read content from documents explicitly marked as forbidden from publishing by accessing search, backlink, asset content, saved criteria, recent documents, graph, and tag endpoints.

Title
OpenChoreo: Cross-project command execution and wirelog view access via OpenChoreo openchoreo-api exec and wirelogs endpoints
Summary
OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.1.6 and 1.2.3, internal/openchoreo-api/api/handlers/exec.go and internal/openchoreo-api/api/handlers/wirelogs.go authorize component:exec and wirelogs:view using the caller-supplied project query parameter instead of comp.Spec.Owner.ProjectName, allowing a user with a project-scoped grant to execute commands in and read wirelogs from components owned by other projects in the same namespace. This vulnerability is fixed in 1.1.6 and 1.2.3.

Title
Apache Syncope: Cross-realm disclosure of confidential ConnId bundles configuration values
Summary
Incorrect Authorization vulnerability in Apache Syncope.
An administrator with adequate entitlements in a given Realm may be able to read via REST the full Connector configuration, confidential properties included, scoped in another Realm and thus be able to effectively duplicate such Connector instance into the Realm they have administration rights for.
This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2.
Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.

Title
vantage6: Algorithm developer can edit another developer's algorithm that is pending / under review
Summary
vantage6 is an open-source infrastructure for privacy preserving analysis. In version 5.0.2 and earlier, the algorithm-store edit permission lacks an ownership check, allowing one algorithm developer to alter another developer's algorithm while it is pending or under review. The attacker can change metadata including the algorithm image or image tag, causing reviewers and nodes to trust a different image from the one originally submitted for approval. No fixed version is available as of this review.

Title
Apache Syncope: Non-recursive Any search could skip Realms restrictions
Summary
Incorrect Authorization vulnerability in Apache Syncope.
Any search requests are transformed into SQL, Neo4J or Elasticsearch / Opensearch queries, depending on the actual deployment configuration.
An important component of such transformation is the Realms filter, which ensures that the search results are matching the requester's permissions.
For non-recursive search requests it is possible that such Realms filter is rendered as empty, thus voiding any restriction on requester privileges.
This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2.
Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.

Summary
An authorization bypass vulnerability exists in Zimbra Collaboration (ZCS) before 10.1.17 due to improper authorization validation in delegated email sending functionality. An authenticated attacker can send specially crafted SOAP requests to impersonate another user and send emails without possessing the required delegation or send-as permissions. This occurs in the SaveDraftRequest SOAP handler.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
No CAPEC attack patterns related to this CWE.
