The version of php installed on the remote host is prior to 5.4.16-46. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2832 advisory.

    An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in     PHP through 7.1.5. A heap out-of-bounds write or read occurs in next_state_val() during regular expression     compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and     fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would     produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds     write memory corruption. (CVE-2017-9226)

    An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function gb18030_mbc_enc_len in file     gb18030.c, a UChar pointer is dereferenced without checking if it passed the end of the matched string.
    This leads to a heap-based buffer over-read. (CVE-2019-19203)

    A flaw was found in PHP. This issue occurs due to an uncaught integer overflow in PDO::quote() of     PDO_SQLite returning an improperly quoted string. With the implementation of sqlite3_snprintf(), it is     possible to force the function to return a single apostrophe if the function is called on user-supplied     input without any length restrictions in place. (CVE-2022-31631)

    In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, core path resolution function     allocate buffer one byte too small. When resolving paths with lengths close to system MAXPATHLEN setting,     this may lead to the byte after the allocated buffer being overwritten with NUL value, which might lead to     unauthorized data access or modification. (CVE-2023-0568)

    In PHP version 8.0.* before 8.0.30,  8.1.* before 8.1.22, and 8.2.* before 8.2.8, when loading phar file,     while reading PHAR directory entries, insufficient length checking may lead to a stack buffer overflow,     leading potentially to memory corruption or RCE. (CVE-2023-3824)

    Erroneous parsing of multipart form data

    NOTE: Fixed in 8.3.12, 8.2.24NOTE: https://github.com/php/php-     src/security/advisories/GHSA-9pqp-7h25-4f32NOTE: https://github.com/php/php-     src/commit/19b49258d0c5a61398d395d8afde1123e8d161e0 (PHP-8.2.24) (CVE-2024-8925)
