Description

This security bulletin contains information about 9 vulnerabilities.


1) Cross-site scripting (CVE-ID: N/A)

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

CVSSv4: CVSS:4.0/AV:N/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 vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The weakness exists due to insufficient sanitization of user-supplied data. 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) Security restrictions bypass (CVE-ID: N/A)

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

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


The vulnerability allows a remote attacker to bypass security restrictions on the target system

The weakness exists due to multiple permission issues. A remote attacker can bypass security restrictions and perform actions on resources which they are not authorized to perform.


3) Information disclosure (CVE-ID: N/A)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system

The weakness exists due to password exposure in System Settings. A remote attacker can view passwords in the System Settings section of the Control Panel.


4) Disk consumption (CVE-ID: N/A)

CWE-ID: CWE-400 - Resource exhaustion

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


The vulnerability allows a remote attacker to cause DoS condition on the target system

The weakness exists due to an error when using Xuggler. A remote attacker can create a large number of temporary files during video playback when Xuggler is enabled for video conversion, trigger disk consumption and cause the service to crash.


5) Privilege escalation (CVE-ID: N/A)

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

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:Clear


The vulnerability allows a remote attacker to gain elevated privileges on the target system.

The weakness exists due to unauthorized access to system portlets/applications. A remote attacker can modify system settings to gain administration privileges.


6) Open redirect (CVE-ID: N/A)

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

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


The vulnerability allows a remote unauthenticated attacker to redirect the target user to external websites.

The weakness exists due to open redirect in Asset Publisher. A remote attacker can use a specially crafted image link, trick the victim into opening it and redirect users to malicious website.

7) Information disclosure (CVE-ID: N/A)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


The vulnerability allows a local attacker to obtain potentially sensitive information on the target system

The weakness exists due to insufficient input validation. A local attacker can submit specially crafted URL and access all files within the application's WAR folder.


8) Spoofing attack (CVE-ID: N/A)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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:Clear


The vulnerability allows a remote attacker to perform spoofing attack.

The weakness exists due to insufficient input validation. A remote attacker can use URL manipulation in applications that support tags to spoof content and mislead users.


9) Improper input validation (CVE-ID: CVE-2017-9801)

CWE-ID: CWE-20 - Improper input validation

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