Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) XXE attack (CVE-ID: CVE-2018-1000632)
The vulnerability allows a remote attacker to conduct XXE attack on the target system.
The vulnerability exists due to improper sanitization of elements and attribute names in XML documents. A remote attacker can trick the victim into opening a specially crafted XML document that submits malicious input, perform XXE attack and bypass security restrictions to access and modify sensitive information on the system.
2) XML Entity Expansion (CVE-ID: CVE-2021-23926)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper input validation when processing XML data. A remote attacker can pass specially crafted XML data to the application and perform XML Entity Expansion attacks.
3) XML External Entity injection (CVE-ID: CVE-2019-12415)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input when using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents. A remote attacker can pass a specially crafted XML code to the affected application and read files from the local filesystem or from internal network resources 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.
4) XML Entity Expansion (CVE-ID: CVE-2017-5644)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to insufficient validation of user-supplied XML input. A local user can pass a specially crafted OOXML file to the affected application and perform a denial of service attack.
5) Exposed dangerous method or function (CVE-ID: CVE-2020-10683)
The vulnerability allows a remote attacker to abuse implemented functionality.
The vulnerability exists due to dom4j allows by default external DTDs and External Entities. A remote attacker can abuse this functionality and perform XXE attack against application that uses dom4j default configuration.
6) Infinite loop (CVE-ID: CVE-2009-2625)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop. A remote attacker can send a malformed XML input to the application, consume all available system resources and cause denial of service conditions.
7) Infinite loop (CVE-ID: CVE-2017-12626)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to infinite loops while parsing specially crafted WMF, EMF, MSG and macros and out of Memory exceptions while parsing specially crafted DOC, PPT and XLS. A remote attacker can cause the service to crash.
8) Input validation error (CVE-ID: CVE-2020-14338)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in Wildfly's implementation of Xerces, specifically in the way the XMLSchemaValidator class in the JAXP component of Wildfly enforced the "use-grammar-pool-only" feature. A remote attacker can pass specially-crafted XML file to the application and manipulate the validation process in certain cases.
