Description

This security bulletin contains information about 3 vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2022-26136)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/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 Servlet Filter. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script 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.


2) Insufficient verification of data authenticity (CVE-ID: CVE-2022-26137)

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

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


The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to origin validation error when processing HTTP requests, related to cross-origin sharing (CORS) in the Servlet Filter. A remote attacker can trick the victim to follow a specially crafted link and access the vulnerable application with the victim’s permissions.


3) Deserialization of Untrusted Data (CVE-ID: CVE-2022-26133)

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:P/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 within the SharedSecretClusterAuthenticator. A remote non-authenticated attacker can send 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.
