According to its banner, the version of PHP running on the remote web server is prior to 7.2.28, 7.3.x prior to 7.3.15, or 7.4.x prior to 7.4.3. It is, therefore, affected by multiple vulnerabilities:

 - A heap buffer overflow exists in phar_extract_file. (CVE-2020-7061)

 - A null pointer dereference exists in PHP session upload progress. (CVE-2020-7062)

 - A file permissions bypass exists when files are added to tar with Phar::buildFromIterator. (CVE-2020-7063)

Note that the scanner 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 7.3.15-1.24. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1351 advisory.

    In PHP versions 7.3.x below 7.3.15 and 7.4.x below 7.4.3, while extracting PHAR files on Windows using     phar extension, certain content inside PHAR file could lead to one-byte read past the allocated buffer.
    This could potentially lead to information disclosure or crash. (CVE-2020-7061)

    In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload     functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0     (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist     and encounter null pointer dereference, which would likely lead to a crash. (CVE-2020-7062)

    In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive     using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all     access) even if the original files on the filesystem were with more restrictive permissions. This may     result in files having more lax permissions than intended when such archive is extracted. (CVE-2020-7063)

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.

The version of php72 installed on the remote host is prior to 7.2.28-1.21. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1350 advisory.

    In PHP versions 7.3.x below 7.3.15 and 7.4.x below 7.4.3, while extracting PHAR files on Windows using     phar extension, certain content inside PHAR file could lead to one-byte read past the allocated buffer.
    This could potentially lead to information disclosure or crash. (CVE-2020-7061)

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.

According to its banner, the version of PHP running on the remote web server is either 7.2.x prior to 7.2.28, 7.3.x prior to 7.3.15, or 7.4.x prior to 7.4.3. It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow condition exists in phar_extract_file()     function due to incorrect loop termination. An unauthenticated, remote     attacker can exploit this to cause a denial of service condition or the     execution of arbitrary code. (CVE-2020-7061)

  - A denial of service (DoS) vulnerability exists in PHP SessionUpload     Progress functions due to Null Pointer Dereference. An unauthenticated,     remote attacker can exploit this issue to cause the php service to stop     responding. (CVE-2020-7062)     
 - An Insecure File Permissions on the buildFromIterator function gives all     access permission to Tar files. (CVE-2020-7063)

The remote host is affected by the vulnerability described in GLSA-202003-57 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly execute arbitrary shell commands, cause a       Denial of Service condition or obtain sensitive information.
  Workaround :

    There is no known workaround at this time.
