"The version of php installed on the remote host is prior to 8.1.29-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2PHP8.1-2024-005 advisory.

    The openssl_private_decrypt function in PHP, when using PKCS1 padding (OPENSSL_PKCS1_PADDING, which is the
    default), is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes the
    changes from this pull request:  https://github.com/openssl/openssl/pull/13817
    (rsa_pkcs1_implicit_rejection). These changes are part of OpenSSL 3.2 and have also been backported to
    stable versions of various Linux distributions, as well as to the PHP builds provided for Windows since
    the previous release. All distributors and builders should ensure that this version is used to prevent PHP
    from being vulnerable.

    PHP Windows builds for the versions 8.1.29, 8.2.20 and 8.3.8 and above include OpenSSL patches that fix
    the vulnerability. (CVE-2024-2408)

    The vulnerability allows a remote attacker to bypass implemented security restrictions.

    The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a
    standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by
    PHP applications.

    Note, the vulnerability exists due to incomplete fix for #VU67756 (CVE-2022-31629). (CVE-2024-2756)

    The vulnerability allows a remote attacker to bypass authentication process.

    The vulnerability exists due to an error in within the password_verify() function, which can erroneously
    return true. A remote attacker can bypass implemented authentication based on the vulnerable function and
    gain unauthorized access to the web application. (CVE-2024-3096)

    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)

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

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