Description
This security bulletin contains information about 14 vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2021-1996)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote privileged user to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Web Services component in Oracle WebLogic Server. A remote privileged user can exploit this vulnerability to gain access to sensitive information.
2) Improper input validation (CVE-ID: CVE-2021-2033)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote authenticated user to perform service disruption.
The vulnerability exists due to improper input validation within the Core Components component in Oracle WebLogic Server. A remote authenticated user can exploit this vulnerability to perform service disruption.
3) Uncontrolled memory allocation (CVE-ID: CVE-2018-10237)
CWE-ID: CWE-789 - Uncontrolled Memory Allocation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to unbounded memory allocation. A remote attacker can cause the service to crash and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable.
4) Cross-site scripting (CVE-ID: CVE-2020-11022)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:P/U:Clear
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.
5) Improper input validation (CVE-ID: CVE-2021-1995)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote authenticated user to manipulate data.
The vulnerability exists due to improper input validation within the Web Services component in Oracle WebLogic Server. A remote authenticated user can exploit this vulnerability to manipulate data.
6) Improper input validation (CVE-ID: CVE-2020-5421)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:L/VI:H/VA:N/SC:L/SI:H/SA:N/E:P/U:Green
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the Core (Spring Framework) component in Oracle Communications Session Report Manager. A remote authenticated user can exploit this vulnerability to read and manipulate data.
7) Improper input validation (CVE-ID: CVE-2021-2109)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote privileged user to execute arbitrary code.
The vulnerability exists due to improper input validation within the Console component in Oracle WebLogic Server. A remote privileged user can exploit this vulnerability to execute arbitrary code.
8) Protection mechanism failure (CVE-ID: CVE-2019-10086)
CWE-ID: CWE-693 - Protection Mechanism Failure
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exist due to Beanutils is not using by default the a special BeanIntrospector class in PropertyUtilsBean that was supposed to suppress the ability for an attacker to access the classloader via the class property available on all Java objects.
