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.
8) Prototype pollution (CVE-ID: CVE-2020-5259)
The disclosed vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to insufficient sanitization of user-supplied data within the jqMix method. A remote attacker can inject and execute arbitrary JavaScript script code.
9) 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.
10) Resource exhaustion (CVE-ID: CVE-2021-36373)
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 TAR archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
11) Resource exhaustion (CVE-ID: CVE-2021-36374)
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 ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
12) Resource exhaustion (CVE-ID: CVE-2022-25857)
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 handling YAML files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
13) Code Injection (CVE-ID: CVE-2021-42550)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote user can send a specially crafted request to the application and execute arbitrary code on the target system by tricking the application to load a malicious configuration from a remote LDAP server.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-11979)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect patch for vulnerability #VU27924 (CVE-2020-1945). Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
15) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.
16) 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.
17) Resource exhaustion (CVE-ID: CVE-2022-42004)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control usage of deeply nested arrays in BeanDeserializer._deserializeFromArray. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
18) Code Injection (CVE-ID: CVE-2020-13936)
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.
19) Input validation error (CVE-ID: CVE-2020-13956)
The vulnerability allows a remote attacker to compromise the affected application.
The vulnerability exists due to insufficient validation of user-supplied input in Apache HttpClient. A remote attacker can pass request URIs to the library as java.net.URI object and force the application to pick the wrong target host for request execution.
20) Security restrictions bypass (CVE-ID: CVE-2018-1313)
The vulnerability allows a remote unauthenticated attacker to bypass security restrictions to the target system.The weakness exists in the Network Server component due to improper security restrictions. If the Derby Network Server is started without specifying a security manager, the Derby Network Server will install a default Java security manager that enforces a basic policy. A remote attacker can send a specially crafted packet and cause the system to boot a database for which the location and contents of the database are under the attacker's control.
21) XXE attack (CVE-ID: CVE-2015-1832)
The vulnerability allows a remote user to conduct XXE attack.The weakness exists due to XML external entity error. Via vectors involving XmlVTI and the XML datatype context-dependent attackers can view arbitrary files that may lead to denial of service.
