"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3810 advisory.

  - In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site
    attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or
    `__Secure-` cookie by PHP applications. (CVE-2022-31629)

  - Due to an incomplete fix to CVE-2022-31629 https://github.com/advisories/GHSA-c43m-486j-j32p , network and
    same-site attackers can set a standard insecure cookie in the victim's browser which is treated as a
    __Host- or __Secure- cookie by PHP applications. (CVE-2024-2756)

  - In PHP version 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, if a password stored with
    password_hash() starts with a null byte (\x00), testing a blank string as the password via
    password_verify() will incorrectly return true. (CVE-2024-3096)

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