The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect handling of user-supplied input in regular expression. A remote attacker can pass specially crafted input to the application and perform regular expression denial of service (ReDoS) attack.

2) Improper input validation (CVE-ID: CVE-2021-22119)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the Policy (Spring Security) component in Oracle Communications Cloud Native Core Policy. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.

3) Resource exhaustion (CVE-ID: CVE-2021-28165)

CWE-ID: CWE-400 - Resource exhaustion

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 when processing large TLS frames. A remote attacker can send specially crafted data to the server, trigger CPU high load and perform a denial of service (DoS) attack.

4) Resource management error (CVE-ID: CVE-2020-17527)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to improper management of internal resources within the application when processing HTTP/2 requests in Apache Tomcat. The web server can re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. As a result a remote attacker can obtain sensitive information from another HTTP request.

5) Input validation error (CVE-ID: CVE-2020-13949)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted messages and perform a denial of service (DoS) attack.

6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-22118)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions in the WebFlux application, which leads to security restrictions bypass and privilege escalation.

7) Deserialization of Untrusted Data (CVE-ID: CVE-2020-36189)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

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 com.newrelic.agent.deps.ch.qos.logback.core.db.DriverManagerConnectionSource. 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.

8) Improper input validation (CVE-ID: CVE-2021-39153)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper input validation. A remote attacker can exploit this vulnerability to execute arbitrary code.

9) Improper Privilege Management (CVE-ID: CVE-2020-15824)

CWE-ID: CWE-269 - Improper Privilege Management

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote authenticated user to execute arbitrary code.

In JetBrains Kotlin from 1.4-M1 to 1.4-RC (as Kotlin 1.3.7x is not affected by the issue. Fixed version is 1.4.0) there is a script-cache privilege escalation vulnerability due to kotlin-main-kts cached scripts in the system temp directory, which is shared by all users by default.

10) Code Injection (CVE-ID: CVE-2020-13936)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation. A remote attacker with ability to modify Velocity templates can inject and execute arbitrary Java code on the system with the same privileges as the account running the Servlet container.

11) Improper input validation (CVE-ID: CVE-2021-27568)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to read data or crash the application.

The vulnerability exists due to improper input validation within the REST Services (netplex json-smart-v1) component in PeopleSoft Enterprise PeopleTools. A remote non-authenticated attacker can exploit this vulnerability to read data or crash the application.

12) Improper input validation (CVE-ID: CVE-2021-32827)

CWE-ID: CWE-20 - Improper input validation
