DescriptionCVE.org

Joomla Extension - fabrikar.com - Unauthenticated SQL injection in list filter condition parameter in Fabrik < 4.7.3 - The condition parameter passed to a list filter is concatenated verbatim into the WHERE clause built by getFilterQuery(). An unauthenticated attacker can supply arbitrary SQL through the filter condition, giving full read of the database.

AnalysisAI

Unauthenticated SQL injection in the Fabrik application-builder extension for Joomla (versions 1.0.0 through 4.7.3, fixed in 4.7.3) lets remote attackers read the entire backing database. The flaw sits in getFilterQuery(), where the user-controlled list-filter 'condition' parameter is concatenated verbatim into a WHERE clause, so no authentication or user interaction is needed. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target Joomla site has the Fabrik extension installed at a version at or below 4.7.3 and exposes a Fabrik list whose filter functionality is reachable by the attacker; the specific trigger is supplying a crafted value in the list filter's 'condition' parameter, which reaches getFilterQuery() and is concatenated into the WHERE clause. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals point to a genuinely high-priority, easily exploitable flaw for anyone running Fabrik. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker browses to a public Joomla page rendering a Fabrik list, then manipulates the list-filter request so the 'condition' parameter carries crafted SQL (e.g., a UNION-based or boolean/time-based payload). Because the value is concatenated straight into the WHERE clause, the attacker extracts arbitrary tables - Joomla user records, session tokens, and configuration secrets. …
Remediation Upgrade Fabrik to version 4.7.3, which per the affected-range data ('< 4.7.3') is the first fixed release - cite the vendor at https://www.fabrikar.com/ for the release, as no dedicated advisory URL was provided in the input and the exact patched build should be confirmed with the vendor. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all systems running Fabrik extension versions prior to 4.7.3, prioritize those handling sensitive or customer data, and prepare emergency patching procedures with change management approval. …
