The combination of primitives offered by SMB and AFP in their default configuration allows the arbitrary writing of files. By exploiting these combination of primitives, an attacker can execute arbitrary code.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6786-1 advisory.

    It was discovered that Netatalk did not properly protect an SMB and AFP

    default configuration. A remote attacker could possibly use this issue to

    execute arbitrary code.

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

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

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-39f0ec3879 advisory.

    3.1.18 release     Security fix for CVE-2022-22995

The remote host is affected by the vulnerability described in GLSA-202311-02 (Netatalk: Multiple Vulnerabilities including root remote code execution)

  - This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations     of Synology DiskStation Manager. Authentication is not required to exploit this vulnerablity. The specific     flaw exists within the processing of DSI structures in Netatalk. The issue results from the lack of proper     validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can     leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12326.
    (CVE-2021-31439)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the ad_addcomment function. The issue results from the lack of proper validation of the length of user-     supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this     vulnerability to execute code in the context of root. Was ZDI-CAN-15876. (CVE-2022-0194)

  - The combination of primitives offered by SMB and AFP in their default configuration allows the arbitrary     writing of files. By exploiting these combination of primitives, an attacker can execute arbitrary code.
    (CVE-2022-22995)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the parse_entries function. The issue results from the lack of proper error handling when parsing     AppleDouble entries. An attacker can leverage this vulnerability to execute code in the context of root.
    Was ZDI-CAN-15819. (CVE-2022-23121)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the setfilparams function. The issue results from the lack of proper validation of the length of user-     supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this     vulnerability to execute code in the context of root. Was ZDI-CAN-15837. (CVE-2022-23122)

  - This vulnerability allows remote attackers to disclose sensitive information on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the getdirparams method. The issue results from the lack of proper validation of user-supplied data, which     can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction     with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-15830.
    (CVE-2022-23123)

  - This vulnerability allows remote attackers to disclose sensitive information on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the get_finderinfo method. The issue results from the lack of proper validation of user-supplied data,     which can result in a read past the end of an allocated buffer. An attacker can leverage this in     conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-     CAN-15870. (CVE-2022-23124)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of     Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within     the copyapplfile function. When parsing the len element, the process does not properly validate the length     of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage     this vulnerability to execute code in the context of root. Was ZDI-CAN-15869. (CVE-2022-23125)

  - Netatalk through 3.1.13 has an afp_getappl heap-based buffer overflow resulting in code execution via a     crafted .appl file. This provides remote root access on some platforms such as FreeBSD (used for TrueNAS).
    (CVE-2022-45188)
