Description

This security bulletin contains information about 7 vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2021-32602)

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:Green


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 FortiPortal GUI. passed via invalid lang parameter or with an invalid org.springframework.web.servlet.i18n.CookieLocaleResolver.LOCALE value. 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) Path traversal (CVE-ID: CVE-2021-36168)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


The vulnerability allows a remote user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in controler. A remote user can send a specially crafted HTTP request and read arbitrary files on the system.


3) Use of a One-Way Hash with a Predictable Salt (CVE-ID: CVE-2021-32596)

CWE-ID: CWE-760 - Use of a One-Way Hash with a Predictable Salt

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


The vulnerability allows an attacker to restore password from password hash.

The vulnerability exists due to FortiPortal uses ne-way hash with a predictable salt when storing passwords. An attacker with access to the password hash can restore password from it by means of precomputed tables.


4) Arbitrary file upload (CVE-ID: CVE-2021-32594)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

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


The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to insufficient validation of files during file upload. A remote user can upload a malicious file to the system and tamper with the underlying system's files.


5) SQL injection (CVE-ID: CVE-2021-32590)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

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:Amber


The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can send a specially crafted HTTP request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


6) Use of hard-coded credentials (CVE-ID: CVE-2021-32588)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

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:Red


The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded Tomcat Manager username and password in application code. A remote unauthenticated attacker can access the affected system using the hard-coded credentials and execute arbitrary commands as root.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) OS Command Injection (CVE-ID: CVE-2021-26104)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

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