Eclipse Memory Analyzer version 1.9.1 and earlier is subject to a deserialization vulnerability if an index file of a parsed heap dump is replaced by a malicious version and the heap dump is reopened in Memory Analyzer. The user must chose to reopen an already parsed heap dump with an untrusted index for the problem to occur. The problem can be averted if the index files from an untrusted source are deleted and the heap dump is opened and reparsed. Also some local configuration data is subject to a deserialization vulnerability if the local data were to be replaced with a malicious version. This can be averted if the local configuration data stored on the file system cannot be changed by an attacker. The vulnerability could possibly allow code execution on the local system.
Eclipse Memory Analyzer version 1.9.1 and earlier is subject to a cross site scripting (XSS) vulnerability when generating an HTML report from a malicious heap dump. The user must chose todownload, open the malicious heap dump and generate an HTML report for the problem to occur. The heap dump could be specially crafted, or could come from a crafted application or from an application processing malicious data. The vulnerability is present whena report is generated and opened from the Memory Analyzer graphical user interface, or when a report generated in batch mode is then opened in Memory Analyzer or by a web browser. The vulnerability could possibly allow code execution on the local system whenthe report is opened in Memory Analyzer.
For Eclipse Che versions 6.16 to 7.3.0, with both authentication and TLS disabled, visiting a malicious web site could trigger the start of an arbitrary Che workspace. Che with no authentication and no TLS is not usually deployed on a public network but is often used for local installations (e.g. on personal laptops). In that case, even if the Che API is not exposed externally, some javascript running in the local browser is able to send requests to it.
In Eclipse Jetty versions 9.4.21.v20190926, 9.4.22.v20191022, and 9.4.23.v20191118, the generation of default unhandled Error response content (in text/html and text/json Content-Type) does not escape Exception messages in stacktraces included in error output.
XMLLanguageService.java in XML Language Server (aka lsp4xml) before 0.9.1, as used in Red Hat XML Language Support (aka vscode-xml) before 0.9.1 for Visual Studio and other products, allows a remote attacker to write to arbitrary files via Directory Traversal.
XML Language Server (aka lsp4xml) before 0.9.1, as used in Red Hat XML Language Support (aka vscode-xml) before 0.9.1 for Visual Studio and other products, allows XXE via a crafted XML document, with resultant SSRF (as well as SMB connection initiation that can lead to NetNTLM challenge/response capture for password cracking). This occurs in extensions/contentmodel/participants/diagnostics/LSPXMLParserConfiguration.java.
From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a diagnostic file are permitted without any privilege checks.
faces/context/PartialViewContextImpl.java in Eclipse Mojarra, as used in Mojarra for Eclipse EE4J before 2.3.10 and Mojarra JavaServer Faces before 2.2.20, allows Reflected XSS because a client window field is mishandled.
