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.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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-2024-42330)

    Several security vulnerabilities have been discovered in zabbix, a network     monitoring solution, potentially among other effects allowing denial of     service, information disclosure, use-after-free or remote code inclusion.


    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-2024-42330

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-2024-42331

        In the src/libs/zbxembed/browser.c file, the es_browser_ctor method         retrieves a heap pointer from the Duktape JavaScript engine. This         heap pointer is subsequently utilized by the browser_push_error         method in the src/libs/zbxembed/browser_error.c file. A         use-after-free bug can occur at this stage if the wd->browser heap         pointer is freed by garbage collection.

    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.

        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

    For Debian 11 bullseye, these problems have been fixed in version     1:5.0.45+dfsg-1+deb11u1.

    We recommend that you upgrade your zabbix packages.
