"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1739821812 advisory.

  - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error,
    filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of
    URLs the function will result in invalid user information (username + password part of URLs) being treated
    as valid user information. This may lead to the downstream code accepting invalid URLs as valid and
    parsing them incorrectly. (CVE-2024-5458)

  - In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, erroneous parsing of
    multipart form data contained in an HTTP POST request could lead to legitimate data not being processed.
    This could lead to malicious attacker able to control part of the submitted data being able to exclude
    portion of other data, potentially leading to erroneous application behavior. (CVE-2024-8925)

  - In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, when using PHP-FPM SAPI and
    it is configured to catch workers output through catch_workers_output = yes, it may be possible to pollute
    the final log or remove up to 4 characters from the log messages by manipulating log message content.
    Additionally, if PHP-FPM is configured to use syslog output, it may be possible to further remove log data
    using the same vulnerability. (CVE-2024-9026)

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