Delft-FEWS uses third party libraries and analyses these libraries using the OWASP dependency check tool. See: https://owasp.org/www-project-dependency-check/
This page keeps track of known CVE issues in libraries that are distributed with Delft-FEWS and the upgrade strategy of these libraries.
Only CVE issues of severity Critical and High are reported here.
| CVE | library | description | Risk for Delft-FEWS | JIRA | upgrade strategy |
|---|---|---|---|---|---|
| CVE-2021-43466 | thymeleaf-3.0.12.RELEASE.jar | In the thymeleaf-spring5:3.0.12 component, thymeleaf combined with specific scenarios in template injection may lead to remote code execution. Comment of Thymeleaf developer: I'd like to explain that CVE-2021-43466 only affects those applications that contain controllers or controller configurations that take a request parameter and directly use it, without previous filtering, as the name of the view to be rendered | Only used in Admin interface where the described scenario is not used. | FEWS-26228 - Getting issue details... STATUS | False positive. No action required. Once version 3.0.13 is available we can upgrade the jar to avoid this false alarm. |
| CVE-2021-33813 | jdom.jar | An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to cause a denial of service via a crafted HTTP request. | Limited risk, since the embeded PI service is not a public facing webservice and the alarm module only uses the library in the client. For most Delft-FEWS users, the library is never used and can be removed. | FEWS-25546 - Getting issue details... STATUS | phase out the xfire library, that has a dependency on jdom. XFire is used in:
|
| CVE-2021-33813 | jdom-2.02.jar | An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to cause a denial of service via a crafted HTTP request. | Might be used in imports that use opendap. But since the library is not used in a service component, the risk is limited. | FEWS-25545 - Getting issue details... STATUS | Dependency of ucar netcdf libraries. JDOM library has been upgraded to: jdom2-2.0.6.1.jar since 2022.01. |
| CVE-2019-7611 | elasticsearch-core-6.4.3.jar | A permission issue was found in Elasticsearch versions before 5.6.15 and 6.6.1 when Field Level Security and Document Level Security are disabled and the _aliases, _shrink, or _split endpoints are used | Elastic search as distributed as part of the archive server and doesn't have Field Level or Document Level Seurity disabled. As long as the provided settings are not changed, there is no risk. | FEWS-25543 - Getting issue details... STATUS | False positive. No need to upgrade since the archive server configuration is correct. Once a fix is available we can upgrade the jar to avoid this false alarm. |
| CVE-2018-1258 | spring-security-core-5.4.8.jar, spring-security-oauth2-core-5.4.8.jar | Spring Framework version 5.0.5 when used in combination with any versions of Spring Security contains an authorization bypass when using method security. An unauthorized malicious user can gain unauthorized access to methods that should be restricted. | False alarm. Spring security is used in the Admin Interface, but doesn't use version 5.0.5 of the spring framework, but a higher version. | FEWS-25865 - Getting issue details... STATUS | False positive. No action required. Once a fix is available we can upgrade the jar to avoid this false alarm. |
| tomcat-embed-core-9.0.50.jar | The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability into Apache Tomcat 10.1.0-M1 to 10.1.0-M8, 10.0.0-M5 to 10.0.14, 9.0.35 to 9.0.56 and 8.5.55 to 8.5.73 that allowed a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore. | False positives. Delft-FEWS web applications don't use web sockets and doesn't use session persistence with the FileStorage. | FEWS-26049 - Getting issue details... STATUS | False positives Upgrade in development only to latest tomcat 9 release. | |
| netty-all-4.1.48.Final.jar | The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack. and The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk. | False alarm. Bzip decoder is not used. Excessive memory usage might lead to a failing FSS in the worst case. Since the Azure IOT Hub is quite well secured, the risk is limited. | False positive. Upgrade in development to latest release. |
