Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper Certificate Validation (CVE-ID: CVE-2020-9488)
The vulnerability allows a remote attacker to perform man-in-the-middle attack.
The vulnerability exists due to the Apache Log4j SMTP appender does not validate SSL certificates. A remote attacker can perform a MitM attack, intercept and decrypt network traffic.
2) Cross-site scripting (CVE-ID: CVE-2020-11022)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the regex operation in "jQuery.htmlPrefilter". A remote attacker can pass specially crafted data to the application that uses .html()</code>, <code>.append() or similar methods for it and execute arbitrary JavaScript code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Improper input validation (CVE-ID: CVE-2020-14757)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Web Services component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
4) Improper input validation (CVE-ID: CVE-2020-14883)
The vulnerability allows a remote privileged user to execute arbitrary code.

5) Improper input validation (CVE-ID: CVE-2020-14820)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
6) Improper input validation (CVE-ID: CVE-2020-14859)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
7) Improper input validation (CVE-ID: CVE-2020-14825)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
8) Improper input validation (CVE-ID: CVE-2020-14841)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Core component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
9) Code Injection (CVE-ID: CVE-2020-14882)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Console component in Oracle WebLogic Server. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
10) Input validation error (CVE-ID: CVE-2019-17267)
The vulnerability allows a remote attacker to compromise the affected application.
The vulnerability exists due to a Polymorphic Typing issue within the net.sf.ehcache.hibernate.EhcacheJtaTransactionManagerLookup component. A remote attacker can execute arbitrary code on he system.
