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.

jetty: generation of default unhandled error response content does not escape exception messages in stacktraces included in error output

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.

JDK: Unrestricted access to diagnostic operations

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.

In Eclipse Mosquitto 1.5.0 to 1.6.5 inclusive, if a malicious MQTT client sends a SUBSCRIBE packet containing a topic that consists of approximately 65400 or more '/' characters, i.e. the topic hierarchy separator, then a stack overflow will occur.

If an MQTT v5 client connects to Eclipse Mosquitto versions 1.6.0 to 1.6.4 inclusive, sets a last will and testament, sets a will delay interval, sets a session expiry interval, and the will delay interval is set longer than the session expiry interval, then a use after free error occurs, which has the potential to cause a crash in some situations.

org.eclipse.paho.client.mqttv3: Improper hostname validation in the MQTT library

In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked. This could allow one MQTT server to impersonate another and provide the client library with incorrect information.

eclipse-birt: report viewer allows reflected XSS in __format url parameter

In Eclipse BIRT versions 1.0 to 4.7, the Report Viewer allows Reflected XSS in URL parameter. Attacker can execute the payload in victim's browser context.

JDK: Failure to privatize a value pulled out of the loop by versioning

All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems.

Prior to 0.1, all builds of Eclipse OMR contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems.

Prior to 0.1, AIX builds of Eclipse OMR contain unused RPATHs which may facilitate code injection and privilege elevation by local users.

JDK: Out-of-bounds access in the String.getBytes method

In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int, byte[], int) method does not verify that the provided byte array is non-null nor that the provided index is in bounds when compiled by the JIT. This allows arbitrary writes to any 32-bit address or beyond the end of a byte array within Java code run under a SecurityManager.

JDK: Insecure RPATH in OpenJ9 on AIX

AIX builds of Eclipse OpenJ9 before 0.15.0 contain unused RPATHs which may facilitate code injection and privilege elevation by local users.

eclipse/buildship: Dependencies being resolved over HTTP instead of HTTPS

In Eclipse Buildship versions prior to 3.1.1, the build files indicate that this project is resolving dependencies over HTTP instead of HTTPS. Any of these artifacts could have been MITM to maliciously compromise them and infect the build artifacts that were produced. Additionally, if any of these JARs or other dependencies were compromised, any developers using these could continue to be infected past updating to fix this.

All Xtext & Xtend versions prior to 2.18.0 were built using HTTP instead of HTTPS file transfer and thus the built artifacts may have been compromised.

Eclipse Vorto versions prior to 0.11 resolved Maven build artifacts for the Xtext project over HTTP instead of HTTPS. Any of these dependent artifacts could have been maliciously compromised by a MITM attack. Hence produced build artifacts of Vorto might be infected.

jetty: error path information disclosure

In Eclipse Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older, the server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches the requested path. The default server behavior on jetty-distribution and jetty-home will include at the end of the Handler tree a DefaultHandler, which is responsible for reporting this 404 error, it presents the various configured contexts as HTML for users to click through to. This produced HTML includes output that contains the configured fully qualified directory base resource location for each context.

jetty: Directory Listing on Windows reveals Resource Base path

In Eclipse Jetty version 9.2.27, 9.3.26, and 9.4.16, the server running on Windows is vulnerable to exposure of the fully qualified Base Resource directory name on Windows to a remote client when it is configured for showing a Listing of directory contents. This information reveal is restricted to only the content in the configured base resource directories.

JDK: Read beyond the end of bytecode array causing JVM crash

In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and rejects the attempted class load.
