Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2020-35491)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data related to org.apache.commons.dbcp2.datasources.SharedPoolDataSource. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Deserialization of untrusted data (CVE-ID: CVE-2018-7489)
The vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2020-35490)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data related to org.apache.commons.dbcp2.datasources.PerUserPoolDataSource. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Out-of-bounds write (CVE-ID: CVE-2020-36518)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger out-of-bounds write and cause a denial of service condition on the target system.
5) Reliance on Reverse DNS Resolution for a Security-Critical Action (CVE-ID: CVE-2020-11971)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to Apache Camel JMX is vulnerable to DNS rebinding attack. A remote attacker can send specially crafted data to the application and perform spoofing attack.
6) Improper Certificate Validation (CVE-ID: CVE-2020-13955)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to HttpUtils#getURLConnection method disables explicitly hostname verification for HTTPS connections making clients vulnerable to man-in-the-middle attacks. Calcite uses internally this method to connect with Druid and Splunk so information leakage may happen when using the respective Calcite adapters.
7) XML External Entity injection (CVE-ID: CVE-2022-39135)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input within the EXISTS_NODE, EXTRACT_XML, XML_TRANSFORM and EXTRACT_VALUE SQL operators. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
