DescriptionCVE.org

A vulnerability was detected in Open-Web-Analytics up to 1.9.1. The impacted element is the function checkCapabilityAndAuthenticateUser of the file Core/Controller.php of the component Controller. Performing a manipulation results in improper authentication. The attack may be initiated remotely. Upgrading to version 1.10.0 is sufficient to resolve this issue. The patch is named 6fc91c49eebdb8bfdfeed71cb50a5d97eac70f24. It is advisable to upgrade the affected component.

AnalysisAI

Unauthenticated schema mutation in Open-Web-Analytics 1.9.x allows remote attackers to invoke the base.updatesApply action - which applies database schema migrations - without any authentication or CSRF protection. The root cause is an opt-in authorization model in checkCapabilityAndAuthenticateUser(): controllers that omit setRequiredCapability() bypass authentication entirely, leaving the schema-mutation endpoint reachable by anyone. …

Vulnerability AssessmentAI

Exploitation The vulnerable endpoint do=base.updatesApply must be reachable over the network - no authentication, no special configuration, and no CSRF token are required on the attacker's part in versions prior to 1.10.0. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.9 with AV:N/AC:L/AT:N/PR:N/UI:N and low impact across all pillars (VC:L/VI:L/VA:L) reflects that while exploitation is trivially easy and requires no authentication, the direct impact of triggering a schema-update operation is bounded - an already-applied migration will be refused, and only instances with pending schema versions are meaningfully vulnerable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to Open-Web-Analytics 1.10.0, available at https://github.com/Open-Web-Analytics/Open-Web-Analytics/releases/tag/1.10.0. … Detailed patch versions, workarounds, and compensating controls in full report.
