Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) XML External Entity injection (CVE-ID: CVE-2020-25649)
The vulnerability allows a remote attacker to modify information on the system.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and modify information on the system.
2) Resource management error (CVE-ID: CVE-2020-8277)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when processing a large number of DNS responses. A Node.js application that allows an attacker to trigger a DNS request
for a host of their choice could trigger a denial of service condition.
3) Resource management error (CVE-ID: CVE-2020-17527)
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.
4) Cross-site scripting (CVE-ID: CVE-2019-0219)
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 passed via a specially crafted gap-iab: URI. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary JavaScript code in the main application's webview on the Android device.
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) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21345)
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. 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.
