Through artifact attestation and the SLSA framework, GitHub's Jennifer Schelkopf argues that at least some supply chain attacks can be stopped in their tracks.

Cybersecurity researchers have shed light on a previously undocumented Rust-based information stealer called Myth Stealer that's being propagated via fraudulent gaming websites. "Upon execution, the malware displays a fake window to appear legitimate while simultaneously decrypting and executing malicious code in the background," Trellix security researchers Niranjan Hegde, Vasantha Lakshmanan

Backdoors lurking in legitimate-looking code contain file-deletion commands that can destroy production systems and cause massive disruptions to software supply chains.

### Summary The Coverage rest api `/workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format}` allow to upload file with a specified url (with {method} equals 'url') with no restrict. ### Details The Coverage rest api `/workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format}` allow to upload file with a specified url (with {method} equals 'url'). But this url has not been check with [URL Checks feature](https://docs.geoserver.org/latest/en/user/security/urlchecks.html#url-checks). For example, should add the code below to check fileURL: ```java URLCheckers.confirm(fileURL) ``` The vulnerable code was [RESTUtils.java](https://github.com/geoserver/geoserver/blob/main/src/rest/src/main/java/org/geoserver/rest/util/RESTUtils.java#L176) ### Impact This vulnerability presents the opportunity for Server Side Request Forgery. ### References - https://osgeo-org.atlassian.net/browse/GEOS-11468 - https://osgeo-org.atlassian.net/browse/GEOS-11717

### Summary The GeoWebCache home page includes version and revision information about the software in use. This information is sensitive from a security point of view because it allows software used by the server to be easily identified. ### Details 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. ### PoC Just open http://localhost:8080/geoserver/gwc/ ### Impact In addition to exposing the version and revision information, the home page will expose the config file and storage locations which may expose the system's temp directory location and whether or not GeoServer is running in a Windows operating system. The approximate server start time and some basic GWC usage information is also exposed. ### References https://osgeo-org.atlassian.net/browse/GEOS-11677 https://g...

### Summary 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. Attacker can abuse this to scan internal networks and gain information about them then exploit further. Moreover, attacker can read limited `.xsd` file on system. ### Details 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. ### Impact An unauthenticated attacker can: 1. Scan internal network to gain insight about it and exploit further. 2. SSRF to endpoint ends with `.xsd`. 3. Read limited `.xsd` file on system. ### Mitigation 1. Define the system property ``ENTITY_RESOLUTION_ALLOWLIST`` to limit the supported external schema locaitons. 2. The buil...

### Summary It possible to achieve Service Side Request Forgery (SSRF) via the Demo request endpoint if Proxy Base URL has not been set. ### Details A unauthenticated user can supply a request that will be issued by the server. This can be used to enumerate internal networks and also in the case of cloud instances can be used to obtain sensitive data. ### Mitigation 1. When using GeoServer with a proxy, manage the proxy base value as a system administrator, use the application property ``PROXY_BASE_URL`` to provide a non-empty value that cannot be overridden by the user interface or incoming request. 2. When using GeoServer directly without a proxy, block all access to TestWfsPost by editing the web.xml file. Adding this block right before the end: ```xml <security-constraint> <web-resource-collection> <web-resource-name>BlockDemoRequests</web-resource-name> <url-pattern>/TestWfsPost/*</url-pattern> </web-resource-coll...
