According to its banner, the version of PHP installed on the remote host is 5.3.x prior to 5.3.28.  It is, therefore, potentially affected by the following vulnerabilities :

  - A flaw exists in the PHP OpenSSL extension's hostname     identity check when handling certificates that contain     hostnames with NULL bytes. An attacker could potentially     exploit this flaw to conduct man-in-the-middle attacks     to spoof SSL servers. Note that to exploit this issue,     an attacker would need to obtain a carefully-crafted     certificate signed by an authority that the client     trusts. (CVE-2013-4073, CVE-2013-4248) 

  - A memory corruption flaw exists in the way the     openssl_x509_parse() function of the PHP OpenSSL     extension parsed X.509 certificates. A remote attacker     could use this flaw to provide a malicious, self-signed     certificate or a certificate signed by a trusted     authority to a PHP application using the aforementioned     function. This could cause the application to crash or     possibly allow the attacker to execute arbitrary code     with the privileges of the user running the PHP     interpreter. (CVE-2013-6420)

Note that this plugin does not attempt to exploit these vulnerabilities, but instead relies only on PHP's self-reported version number.

According to the versions of the ruby packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Ruby 1.8.7 before patchlevel 371, 1.9.3 before     patchlevel 286, and 2.0 before revision r37068 allows     context-dependent attackers to bypass safe-level     restrictions and modify untainted strings via the     name_err_mesg_to_str API function, which marks the     string as tainted, a different vulnerability than     CVE-2011-1005.(CVE-2012-4466)

  - The REXML parser in Ruby 1.9.x before 1.9.3 patchlevel     551, 2.0.x before 2.0.0 patchlevel 598, and 2.1.x     before 2.1.5 allows remote attackers to cause a denial     of service (CPU and memory consumption) a crafted XML     document containing an empty string in an entity that     is used in a large number of nested entity references,     aka an XML Entity Expansion (XEE) attack. NOTE: this     vulnerability exists because of an incomplete fix for     CVE-2013-1821 and CVE-2014-8080.(CVE-2014-8090)

  - Algorithmic complexity vulnerability in     Gem::Version::VERSION_PATTERN in     lib/rubygems/version.rb in RubyGems before 1.8.23.1,     1.8.24 through 1.8.25, 2.0.x before 2.0.8, and 2.1.x     before 2.1.0, as used in Ruby 1.9.0 through 2.0.0p247,     allows remote attackers to cause a denial of service     (CPU consumption) via a crafted gem version that     triggers a large amount of backtracking in a regular     expression.(CVE-2013-4287)

  - The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x     before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote     attackers to cause a denial of service (memory     consumption) via a crafted XML document, aka an XML     Entity Expansion (XEE) attack.(CVE-2014-8080)

  - The OpenSSL::SSL.verify_certificate_identity function     in lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374,     1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247 does     not properly handle a '\\0' character in a domain name     in the Subject Alternative Name field of an X.509     certificate, which allows man-in-the-middle attackers     to spoof arbitrary SSL servers via a crafted     certificate issued by a legitimate Certification     Authority, a related issue to     CVE-2009-2408.(CVE-2013-4073)

  - The rb_get_path_check function in file.c in Ruby 1.9.3     before patchlevel 286 and Ruby 2.0.0 before r37163     allows context-dependent attackers to create files in     unexpected locations or with unexpected names via a NUL     byte in a file path.(CVE-2012-4522)

  - (1) DL and (2) Fiddle in Ruby 1.9 before 1.9.3     patchlevel 426, and 2.0 before 2.0.0 patchlevel 195, do     not perform taint checking for native functions, which     allows context-dependent attackers to bypass intended     $SAFE level restrictions.(CVE-2013-2065)

  - Algorithmic complexity vulnerability in     Gem::Version::ANCHORED_VERSION_PATTERN in     lib/rubygems/version.rb in RubyGems before 1.8.23.2,     1.8.24 through 1.8.26, 2.0.x before 2.0.10, and 2.1.x     before 2.1.5, as used in Ruby 1.9.0 through 2.0.0p247,     allows remote attackers to cause a denial of service     (CPU consumption) via a crafted gem version that     triggers a large amount of backtracking in a regular     expression. NOTE: this issue is due to an incomplete     fix for CVE-2013-4287.(CVE-2013-4363)

  - Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before     r37575 computes hash values without properly     restricting the ability to trigger hash collisions     predictably, which allows context-dependent attackers     to cause a denial of service (CPU consumption) via     crafted input to an application that maintains a hash     table, as demonstrated by a universal multicollision     attack against a variant of the MurmurHash2 algorithm,     a different vulnerability than     CVE-2011-4815.(CVE-2012-5371)

  - Off-by-one error in the encodes function in pack.c in     Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when     using certain format string specifiers, allows     context-dependent attackers to cause a denial of     service (segmentation fault) via vectors that trigger a     stack-based buffer overflow.(CVE-2014-4975)

  - Heap-based buffer overflow in Ruby 1.8, 1.9 before     1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0     preview2, and trunk before revision 43780 allows     context-dependent attackers to cause a denial of     service (segmentation fault) and possibly execute     arbitrary code via a string that is converted to a     floating point value, as demonstrated using (1) the     to_f method or (2) JSON.parse.(CVE-2013-4164)

  - It was found that the methods from the Dir class did     not properly handle strings containing the NULL byte.
    An attacker, able to inject NULL bytes in a path, could     possibly trigger an unspecified behavior of the ruby     script.(CVE-2018-8780)

  - Ruby 1.9.3 before patchlevel 286 and 2.0 before     revision r37068 allows context-dependent attackers to     bypass safe-level restrictions and modify untainted     strings via the (1) exc_to_s or (2) name_err_to_s API     function, which marks the string as tainted, a     different vulnerability than CVE-2012-4466. NOTE: this     issue might exist because of a CVE-2011-1005     regression.(CVE-2012-4464)

  - An issue was discovered in the OpenSSL library in Ruby     before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2,     and 2.6.x before 2.6.0-preview3. When two     OpenSSL::X509::Name objects are compared using ==,     depending on the ordering, non-equal objects may return     true. When the first argument is one character longer     than the second, or the second argument contains a     character that is one less than a character in the same     position of the first argument, the result of == will     be true. This could be leveraged to create an     illegitimate certificate that may be accepted as     legitimate and then used in signing or encryption     operations.(CVE-2018-16395)

  - An issue was discovered in Ruby before 2.3.8, 2.4.x     before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before     2.6.0-preview3. It does not taint strings that result     from unpacking tainted strings with some     formats.(CVE-2018-16396)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Solaris system is missing necessary patches to address security updates :

  - The safe-level feature in Ruby 1.8.6 through 1.8.6-420,     1.8.7 through 1.8.7-330, and 1.8.8dev allows     context-dependent attackers to modify strings via the     Exception#to_s method, as demonstrated by changing an     intended pathname. (CVE-2011-1005)

  - The safe-level feature in Ruby 1.8.7 allows     context-dependent attackers to modify strings via the     NameError#to_s method when operating on Ruby objects.
    NOTE: this issue is due to an incomplete fix for     CVE-2011-1005. (CVE-2012-4481)

  - The OpenSSL::SSL.verify_certificate_identity function in     lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374, 1.9     before 1.9.3-p448, and 2.0 before 2.0.0-p247 does not     properly handle a '\0' character in a domain name in the     Subject Alternative Name field of an X.509 certificate,     which allows man-in-the-middle attackers to spoof     arbitrary SSL servers via a crafted certificate issued     by a legitimate Certification Authority, a related issue     to CVE-2009-2408.
