TencentOS Server 4: zabbix (TSSA-2024:1129)

high Nessus Plugin ID 239993

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1129 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2024-42333:
The researcher is showing that it is possible to leak a small amount of Zabbix Server memory using an out of bounds read in src/libs/zbxmedia/email.c

CVE-2024-42332:
The researcher is showing that due to the way the SNMP trap log is parsed, an attacker can craft an SNMP trap with additional lines of information and have forged data show in the Zabbix UI. This attack requires SNMP auth to be off and/or the attacker to know the community/auth details. The attack requires an SNMP item to be configured as text on the target host.

CVE-2024-42330:
The HttpRequest object allows to get the HTTP headers from the server's response after sending the request. The problem is that the returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. This allows to create internal strings that can be used to access hidden properties of objects.

CVE-2024-42327:
A non-admin user account on the Zabbix frontend with the default User role, or with any other role that gives API access can exploit this vulnerability. An SQLi exists in the CUser class in the addRelatedObjects function, this function is being called from the CUser.get function which is available for every user who has API access.

CVE-2024-36467:
An authenticated user with API access (e.g.: user with default User role), more specifically a user with access to the user.update API endpoint is enough to be able to add themselves to any group (e.g.: Zabbix Administrators), except to groups that are disabled or having restricted GUI access.

CVE-2024-36466:
A bug in the code allows an attacker to sign a forged zbx_session cookie, which then allows them to sign in with admin permissions.

CVE-2024-36464:
When exporting media types, the password is exported in the YAML in plain text. This appears to be a best practices type issue and may have no actual impact. The user would need to have permissions to access the media types and therefore would be expected to have access to these passwords.

CVE-2024-36463:
The implementation of atob in Zabbix JS allows to create a string with arbitrary content and use it to access internal properties of objects.

CVE-2024-36461:
Within Zabbix, users have the ability to directly modify memory pointers in the JavaScript engine.

CVE-2024-36460:
The front-end audit log allows viewing of unprotected plaintext passwords, where the passwords are displayed in plain text.

CVE-2024-22123:
Setting SMS media allows to set GSM modem file. Later this file is used as Linux device. But due everything is a file for Linux, it is possible to set another file, e.g. log file and zabbix_server will try to communicate with it as modem. As a result, log file will be broken with AT commands and small part for log file content will be leaked to UI.

CVE-2024-22122:
Zabbix allows to configure SMS notifications. AT command injection occurs on Zabbix Server because there is no validation of Number field on Web nor on Zabbix server side. Attacker can run test of SMS providing specially crafted phone number and execute additional AT commands on modem.

CVE-2024-22121:
A non-admin user can change or remove important features within the Zabbix Agent application, thus impacting the integrity and availability of the application.

CVE-2024-22120:
Zabbix server can perform command execution for configured scripts. After command is executed, audit entry is added to Audit Log. Due to clientip field is not sanitized, it is possible to injection SQL into clientip and exploit time based blind SQL injection.

CVE-2024-22117:
When a URL is added to the map element, it is recorded in the database with sequential IDs. Upon adding a new URL, the system retrieves the last sysmapelementurlid value and increments it by one. However, an issue arises when a user manually changes the sysmapelementurlid value by adding sysmapelementurlid + 1.
This action prevents others from adding URLs to the map element.

CVE-2024-22114:
User with no permission to any of the Hosts can access and view host count & other statistics through System Information Widget in Global View Dashboard.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
