Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - Asterisk 是一个开源专用小交换机 (PBX) 和电话工具包。低于 asterisk 版本 18.24.2、 20.9.2和 21.4.2 以及 Certified-asterisk 版本 18.9-cert11 和 20.7-cert2 的之前的 AMI 用户可通过“write=originate”更改“/etc/asterisk/”目录中的所有配置文件。出现这种情况的原因是它们不仅能够 curl 远程文件并将其写入磁盘还能够使用“SET”应用程序内的“FILE”函数附加到现有文件。此问题可能会通过任意协议导致权限升级、远程代码执行和/或盲目服务器端请求伪造。
    Asterisk 版本 18.24.2、 20.9.2和 21.4.2 以及 Certified-asterisk 版本 18.9-cert11 和 20.7-cert2 中包含针对此问题的补丁。 (CVE-2024-42365)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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

  - Asterisk is an open source private branch exchange (PBX) and telephony toolkit. Prior to asterisk versions     18.24.2, 20.9.2, and 21.4.2 and certified-asterisk versions 18.9-cert11 and 20.7-cert2, an AMI user with     `write=originate` may change all configuration files in the `/etc/asterisk/` directory. This occurs     because they are able to curl remote files and write them to disk, but are also able to append to existing     files using the `FILE` function inside the `SET` application. This issue may result in privilege     escalation, remote code execution and/or blind server-side request forgery with arbitrary protocol.
    Asterisk versions 18.24.2, 20.9.2, and 21.4.2 and certified-asterisk versions 18.9-cert11 and 20.7-cert2     contain a fix for this issue. (CVE-2024-42365)

Note that Nessus relies on the presence of the package as reported by the vendor.

    Two issues have been found in asterisk, an Open Source Private Branch     Exchange.


    CVE-2024-42365

        Due to a privilege escalation, remote code execution and/or         blind server-side request forgery with arbitrary protocol are         possible.

    CVE-2024-42491

        Due to bad handling of malformed Contact or Record-Route URI in an         incoming  SIP request, Asterisk might crash when res_resolver_unbound         is used.

    Thanks to Niels Galjaard, a minor privilege escalation has been fixed.
