Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Insufficient verification of data authenticity (CVE-ID: CVE-2019-11269)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to the application relies on the URL passed via the "redirect_uri" parameter. A remote attacker can create a specially crafted link that once clicked will cause the authorization server to redirect the resource owner user-agent to a URI under the control of the attacker after successful authentication. As a result the attacker can gain authorization code and bypass OAuth authentication.
2) Use of insufficiently random values (CVE-ID: CVE-2020-5408)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the affected software uses a fixed null initialization vector with CBC Mode in the implementation of the queryable text encryptor. A remote authenticated attacker can derive the unencrypted values using a dictionary attack.
3) Information disclosure (CVE-ID: CVE-2019-12399)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output within the Apache Kafka Connect REST API tasks endpoint. A remote authenticated user can issue a request to the same Connect cluster to obtain the connector's task configurations and the response will contain the plaintext secret.
4) Incorrect default permissions (CVE-ID: CVE-2020-1945)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to Apache Ant is using a default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process. A local user with access to the system can view contents of files and directories or modify them.
5) Resource exhaustion (CVE-ID: CVE-2020-11612)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
