RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of recovery volumes. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21233.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6569-1 advisory.

    it was discovered that libclamunrar incorrectly handled directories when extracting RAR archives. A remote     attacker could possibly use this issue to overwrite arbitrary files and execute arbitrary code. This issue     only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2022-30333)

    It was discovered that libclamunrar incorrectly validated certain structures when extracting RAR archives.
    A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2023-40477)

The remote host is affected by the vulnerability described in GLSA-202309-04 (RAR, UnRAR: Arbitrary File Overwrite)

  - RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract     (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and     Android RAR are unaffected. (CVE-2022-30333)

  - The vulnerability exists due to improper validation of array index when processing recovery volumes. A     remote attacker can trick the victim to open a specially crafted archive and execute arbitrary code on the     system. (CVE-2023-40477)
