In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

The version of php72 installed on the remote host is prior to 7.2.26-1.19. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2024-1921 advisory.

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function accepts     filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths that the code is allowed to access. (CVE-2019-11044)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths that the code is allowed to access. (CVE-2019-11045)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some     systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with     string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can     read to disclosure of the content of some memory locations. (CVE-2019-11046)

  - When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what     will cause it to read past the allocated buffer. This may lead to information disclosure or crash.
    (CVE-2019-11047, CVE-2019-11050)

  - In PHP versions 7.3.x below 7.3.13 and 7.4.0 on Windows, when supplying custom headers to mail() function,     due to mistake introduced in commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, if the header is supplied in     lowercase, this can result in double-freeing certain memory locations. (CVE-2019-11049)

  - cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements,     which allows a heap-based buffer overflow (4-byte out-of-bounds write). (CVE-2019-18218)

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

The version of php73 installed on the remote host is prior to 7.3.13-1.22. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2024-1918 advisory.

This may lead to information disclosure or crash.
    (CVE-2019-11047, CVE-2019-11050)

  - In PHP versions 7.3.x below 7.3.13 and 7.4.0 on Windows, when supplying custom headers to mail() function,     due to mistake introduced in commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, if the header is supplied in     lowercase, this can result in double-freeing certain memory locations.

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

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is less than 5.19.0 and is therefore affected by multiple vulnerabilities in the following components: 
  - Apache FOP
  - Underscore
  - Handlebars
  - PHP
  - sqlite

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access. (CVE-2019-11045)

This may lead to information disclosure or crash. (CVE-2019-11047)

A flaw was discovered in the link function in PHP. When compiled on Windows, it does not correctly handle paths containing NULL bytes. An attacker could abuse this flaw to bypass application checks on file paths. (CVE-2019-11044)

When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash. (CVE-2019-11050)

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations. (CVE-2019-11046)

According to its banner, the version of PHP running on the remote web server is prior to 7.2.26, 7.3.x prior to 7.3.13, or 7.4.x prior to 7.4.1. It is, therefore, affected by multiple vulnerabilities:

 - An arbitrary file read vulnerability exists in link() and DirectoryIterator class due to improper handling of embedded \0 byte character and treats them as terminating at that byte. An attacker can exploit this to disclose information in applications checking paths that the code is allowed to access. (CVE-2019-11044 / CVE-2019-11045)

 - An out-of-bounds READ error exists in the bcmath extension due to an input validation error. An unauthenticated, remote attacker can exploit this by supplying a string containing characters that are identified as numeric by the OS but are not ASCII number. This can cause lead to the disclosure of information within some memory locations. (CVE-2019-11046)

 - An out-of-bounds READ error exists in parsing EXIF information from an image. An unauthenticated, remote attacker can exploit this and supply it iwth data that will cause it to read past the allocated buffer disclosing of information. (CVE-2019-11047 / CVE-2019-11050)

 - A denial of service (DoS) vulnerability exists in mail() due to the double-freeing of certain memory locations. An unauthenticated, remote attacker can exploit this issue, by supplying custom headers, and to cause the application to segfault and stop responding.

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