CVE-2021-41971 1 Apache 1 Superset 2021-10-22 6.0 MEDIUM 8.8 HIGH
Apache Superset up to and including 1.3.0 when configured with ENABLE_TEMPLATE_PROCESSING on (disabled by default) allowed SQL injection when a malicious authenticated user sends an http request with a custom URL.
CVE-2021-32609 1 Apache 1 Superset 2021-10-22 3.5 LOW 5.4 MEDIUM
Apache Superset up to and including 1.1 does not sanitize titles correctly on the Explore page. This allows an attacker with Explore access to save a chart with a malicious title, injecting html (including scripts) into the page.
CVE-2021-33037 3 Apache, Debian, Oracle 4 Tomcat, Tomee, Debian Linux and 1 more 2021-10-22 5.0 MEDIUM 5.3 MEDIUM
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
CVE-2021-30639 1 Apache 1 Tomcat 2021-10-22 5.0 MEDIUM 7.5 HIGH
A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. This issue affects Apache Tomcat 10.0.3 to 10.0.4; 9.0.44; 8.5.64.
CVE-2021-42340 1 Apache 1 Tomcat 2021-10-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2021-36160 3 Apache, Debian, Fedoraproject 3 Http Server, Debian Linux, Fedora 2021-10-20 5.0 MEDIUM 7.5 HIGH
A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive).
CVE-2020-9492 1 Apache 1 Hadoop 2021-10-20 6.5 MEDIUM 8.8 HIGH
In Apache Hadoop 3.2.0 to 3.2.1, 3.0.0-alpha1 to 3.1.3, and 2.0.0-alpha to 2.10.0, WebHDFS client might send SPNEGO authorization header to remote URL without proper verification.
CVE-2021-21409 5 Apache, Debian, Netapp and 2 more 7 Kudu, Zookeeper, Debian Linux and 4 more 2021-10-20 5.0 MEDIUM 5.9 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final.
CVE-2021-21295 5 Apache, Debian, Netapp and 2 more 6 Kudu, Debian Linux, Oncommand Api Services and 3 more 2021-10-20 2.6 LOW 5.9 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.60.Final there is a vulnerability that enables request smuggling. If a Content-Length header is present in the original HTTP/2 request, the field is not validated by `Http2MultiplexHandler` as it is propagated up. This is fine as long as the request is not proxied through as HTTP/1.1. If the request comes in as an HTTP/2 stream, gets converted into the HTTP/1.1 domain objects (`HttpRequest`, `HttpContent`, etc.) via `Http2StreamFrameToHttpObjectCodec `and then sent up to the child channel's pipeline and proxied through a remote peer as HTTP/1.1 this may result in request smuggling. In a proxy case, users may assume the content-length is validated somehow, which is not the case. If the request is forwarded to a backend channel that is a HTTP/1.1 connection, the Content-Length now has meaning and needs to be checked. An attacker can smuggle requests inside the body as it gets downgraded from HTTP/2 to HTTP/1.1. For an example attack refer to the linked GitHub Advisory. Users are only affected if all of this is true: `HTTP2MultiplexCodec` or `Http2FrameCodec` is used, `Http2StreamFrameToHttpObjectCodec` is used to convert to HTTP/1.1 objects, and these HTTP/1.1 objects are forwarded to another remote peer. This has been patched in 4.1.60.Final As a workaround, the user can do the validation by themselves by implementing a custom `ChannelInboundHandler` that is put in the `ChannelPipeline` behind `Http2StreamFrameToHttpObjectCodec`.
CVE-2021-38295 1 Apache 1 Couchdb 2021-10-20 6.0 MEDIUM 7.3 HIGH
In Apache CouchDB, a malicious user with permission to create documents in a database is able to attach a HTML attachment to a document. If a CouchDB admin opens that attachment in a browser, e.g. via the CouchDB admin interface Fauxton, any JavaScript code embedded in that HTML attachment will be executed within the security context of that admin. A similar route is available with the already deprecated _show and _list functionality. This privilege escalation vulnerability allows an attacker to add or remove data in any database or make configuration changes. This issue affected Apache CouchDB prior to 3.1.2
CVE-2021-26291 2 Apache, Quarkus 2 Maven, Quarkus 2021-10-20 6.4 MEDIUM 9.1 CRITICAL
Apache Maven will follow repositories that are defined in a dependency’s Project Object Model (pom) which may be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior in 3.8.1+ to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. See this link for more information about repository management: https://maven.apache.org/repository-management.html
CVE-2021-36374 1 Apache 1 Ant 2021-10-20 4.3 MEDIUM 5.5 MEDIUM
When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected.
CVE-2021-36090 1 Apache 2 Commons Compress, Drill 2021-10-20 5.0 MEDIUM 7.5 HIGH
When reading a specially crafted ZIP archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' zip package.
CVE-2021-36373 1 Apache 1 Ant 2021-10-20 4.3 MEDIUM 5.5 MEDIUM
When reading a specially crafted TAR archive an Apache Ant build can be made to allocate large amounts of memory that finally leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Apache Ant prior to 1.9.16 and 1.10.11 were affected.
CVE-2021-28163 4 Apache, Eclipse, Fedoraproject and 1 more 15 Ignite, Solr, Jetty and 12 more 2021-10-20 4.0 MEDIUM 2.7 LOW
In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory.
CVE-2021-27807 2 Apache, Fedoraproject 2 Pdfbox, Fedora 2021-10-20 4.3 MEDIUM 5.5 MEDIUM
A carefully crafted PDF file can trigger an infinite loop while loading the file. This issue affects Apache PDFBox version 2.0.22 and prior 2.0.x versions.
CVE-2021-29425 2 Apache, Debian 5 Commons Io, Pluto, Whisker and 2 more 2021-10-20 5.0 MEDIUM 5.3 MEDIUM
In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value.
CVE-2021-25329 2 Apache, Debian 2 Tomcat, Debian Linux 2021-10-20 4.4 MEDIUM 7.0 HIGH
The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.
CVE-2021-27906 2 Apache, Fedoraproject 2 Pdfbox, Fedora 2021-10-20 4.3 MEDIUM 5.5 MEDIUM
A carefully crafted PDF file can trigger an OutOfMemory-Exception while loading the file. This issue affects Apache PDFBox version 2.0.22 and prior 2.0.x versions.
CVE-2021-35516 1 Apache 1 Commons Compress 2021-10-20 5.0 MEDIUM 7.5 HIGH
When reading a specially crafted 7Z archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' sevenz package.
