If anonymous read enabled, it's possible to read the database file directly without logging in.

The Apache XML-RPC (aka ws-xmlrpc) library 3.1.3, as used in Apache Archiva, allows remote attackers to execute arbitrary code via a crafted serialized Java object in an <ex:serializable> element.

UNSUPPORTED WHEN ASSIGNED Incorrect Authorization vulnerability in Apache Archiva.

Apache Archiva has a setting to disable user registration, however this restriction can be bypassed. As Apache Archiva has been retired, we do not expect to release a version of Apache Archiva that fixes this issue. You are recommended to look into migrating to a different solution, or isolate your instance from any untrusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer

UNSUPPORTED WHEN ASSIGNED

Incorrect Authorization vulnerability in Apache Archiva: a vulnerability in Apache Archiva allows an unauthenticated attacker to modify account data, potentially leading to account takeover.

This issue affects Apache Archiva: from 2.0.0.

As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Multiple cross-site request forgery (CSRF) vulnerabilities in Apache Archiva 1.3.9 and earlier allow remote attackers to hijack the authentication of administrators for requests that (1) add new repository proxy connectors via the token parameter to admin/addProxyConnectorcommit.action, (2) new repositories via the token parameter to admin/addRepositorycommit.action, (3) edit existing repositories via the token parameter to admin/editRepositorycommit.action, (4) add legacy artifact paths via the token parameter to admin/addLegacyArtifactPathcommit.action, (5) change the organizational appearance via the token parameter to admin/saveAppearance.action, or (6) upload new artifacts via the token parameter to uploadsubmit.action.

Several REST service endpoints of Apache Archiva are not protected against Cross Site Request Forgery (CSRF) attacks. A malicious site opened in the same browser as the archiva site, may send an HTML response that performs arbitrary actions on archiva services, with the same rights as the active archiva session (e.g. administrator rights).
