GHSA-582q-v28r-7cxr
No affected components available
Summary
GeoNetwork's Elasticsearch-backed search API is responsible for injecting access-control and visibility filters into every request before it reaches the underlying Elasticsearch index. Under certain request conditions, that filtering step does not run, allowing an unauthenticated user to retrieve indexed metadata records that should be restricted, including records limited to specific groups.
Details
The search proxy layer forwards client-supplied search requests to Elasticsearch after adding GeoNetwork's own access-control and filter clauses. A flaw in how that filter-injection step is triggered means it can be skipped under certain conditions, so the affected request reaches Elasticsearch without the intended access restrictions applied.
Impact
This is an authorization bypass leading to information disclosure (CWE-862: Missing Authorization). The skipped filter step is responsible for enforcing several layers of access control at once: group-based record visibility, draft record exclusion, record ownership checks, and portal-specific filtering.
Any public-facing GeoNetwork 4.x instance (4.0.0-alpha.1 through 4.4.10) is affected. An unauthenticated attacker can retrieve the full contents of metadata records that should not be publicly visible.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
