Osgeo: Security Vulnerabilities
MapServer is a system for developing web-based GIS applications. Starting in version 4.2 and prior to version 8.6.1, a heap-buffer-overflow write in MapServer’s SLD (Styled Layer Descriptor) parser lets a remote, unauthenticated attacker crash the MapServer process by sending a crafted SLD with more than 100 Threshold elements inside a ColorMap/Categorize structure (commonly reachable via WMS GetMap with SLD_BODY). Version 8.6.1 patches the issue.

Geonetwork 3.10 through 4.2.0 contains an XML external entity vulnerability in PDF rendering that allows attackers to retrieve arbitrary files from the server. Attackers can exploit the insecure XML parser by crafting a malicious XML document with external entity references to read system files through the baseURL parameter in PDF creation requests.

MapServer is a system for developing web-based GIS applications. Prior to 8.4.1, the XML Filter Query directive PropertyName is vulnerably to Boolean-based SQL injection. It seems like expression checking is bypassed by introducing double quote characters in the PropertyName. Allowing to manipulate backend database queries. This vulnerability is fixed in 8.4.1.

GeoServer is an open source server that allows users to share and edit geospatial data. GeoTools Schema class use of Eclipse XSD library to represent schema data structure is vulnerable to XML External Entity (XXE) exploit. This impacts whoever exposes XML processing with gt-xsd-core involved in parsing, when the documents carry a reference to an external XML schema. The gt-xsd-core Schemas class is not using the EntityResolver provided by the ParserHandler (if any was configured). This also impacts users of gt-wfs-ng DataStore where the ENTITY_RESOLVER connection parameter was not being used as intended. This vulnerability is fixed in GeoTools 33.1, 32.3, 31.7, and 28.6.1, GeoServer 2.27.1, 2.26.3, and 2.25.7, and GeoNetwork 4.4.8 and 4.2.13.

GeoServer is an open source server that allows users to share and edit geospatial data. Malicious Jiffle scripts can be executed by GeoServer, either as a rendering transformation in WMS dynamic styles or as a WPS process, that can enter an infinite loop to trigger denial of service. This vulnerability is fixed in 2.27.0, 2.26.3, and 2.25.7. This vulnerability can be mitigated by disabling WMS dynamic styling and the Jiffle process.

GeoServer is an open source server that allows users to share and edit geospatial data. The Coverage rest api /workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format} allows attackers to upload files with a specified url (with {method} equals 'url') with no restrict. This vulnerability is fixed in 2.26.0.

GeoServer is an open source server that allows users to share and edit geospatial data. It is possible to bypass the default REST API security and access the index page. The REST API security handles rest and its subpaths but not rest with an extension (e.g., rest.html). The REST API index can disclose whether certain extensions are installed. This vulnerability is fixed in 2.26.3 and 2.25.6. As a workaround, in ${GEOSERVER_DATA_DIR}/security/config.xml, change the paths for the rest filter to /rest.*,/rest/** and change the paths for the gwc filter to /gwc/rest.*,/gwc/rest/** and restart GeoServer.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. It possible to achieve Service Side Request Forgery (SSRF) via the Demo request endpoint if Proxy Base URL has not been set. Upgrading to GeoServer 2.24.4, or 2.25.2, removes the TestWfsPost servlet resolving this issue.

GeoServer is an open source server that allows users to share and edit geospatial data. An improper URI validation vulnerability exists that enables an unauthorized attacker to perform XML External Entities (XEE) attack, then send GET request to any HTTP server. By default, GeoServer use PreventLocalEntityResolver class from GeoTools to filter out malicious URIs in XML entities before resolving them. The URI must match the regex (?i)(jar:file|http|vfs)[^?#;]*\\.xsd. But the regex leaves a chance for attackers to request to any HTTP server or limited file. Attacker can abuse this to scan internal networks and gain information about them then exploit further. GeoServer 2.25.0 and greater default to the use of ENTITY_RESOLUTION_ALLOWLIST and does not require you to provide a system property.

GeoServer is an open source server that allows users to share and edit geospatial data. org.geowebcache.GeoWebCacheDispatcher.handleFrontPage(HttpServletRequest, HttpServletResponse) has no check to hide potentially sensitive information from users except for a hidden system property to hide the storage locations that defaults to showing the locations. This vulnerability is fixed in 2.26.2 and 2.25.6.
