HPE System Management Homepage before v7.6 allows remote attackers to have an unspecified impact via unknown vectors, related to a "Buffer Overflow" issue.

The HP System Management Homepage (SMH) running on the remote host is affected by a remote code execution vulnerability due to an overflow condition in the mod_smh_config.so library caused by improper validation of user-supplied input when parsing the admin-group parameter supplied to the /proxy/SetSMHData endpoint. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a denial of service condition or the execution of arbitrary code. 

Note that HP SMH is reportedly affected by additional vulnerabilities; however, this plugin has not tested for them.

According to its banner, the version of HP System Management Homepage (SMH) hosted on the remote web server is prior to 7.6. It is, therefore, affected by the following vulnerabilities :

  - A heap buffer overflow condition exists in OpenSSL in     the EVP_EncodeUpdate() function within file     crypto/evp/encode.c that is triggered when handling     a large amount of input data. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2016-2105)

  - A heap buffer overflow condition exists in OpenSSL in     the EVP_EncryptUpdate() function within file     crypto/evp/evp_enc.c that is triggered when handling a     large amount of input data after a previous call occurs     to the same function with a partial block. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2016-2106)

  - Multiple flaws exist OpenSSL in the     aesni_cbc_hmac_sha1_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha1.c and the     aesni_cbc_hmac_sha256_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered     when the connection uses an AES-CBC cipher and AES-NI     is supported by the server. A man-in-the-middle attacker     can exploit these to conduct a padding oracle attack,     resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - Multiple unspecified flaws exist in OpenSSL in the d2i     BIO functions when reading ASN.1 data from a BIO due to     invalid encoding causing a large allocation of memory.
    An unauthenticated, remote attacker can exploit these to     cause a denial of service condition through resource     exhaustion. (CVE-2016-2109)

  - A certificate validation bypass vulnerability exists in     cURL and libcurl due to improper validation of TLS     certificates. A man-in-the-middle attacker can exploit     this, via a spoofed certificate that appears valid, to     disclose or manipulate transmitted data. (CVE-2016-3739)

  - An integer overflow condition exists in PHP in the     php_raw_url_encode() function within file     ext/standard/url.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to have an unspecified impact.
    (CVE-2016-4070)     
  - A flaw exists in PHP in the php_snmp_error() function     within file ext/snmp/snmp.c that is triggered when     handling format string specifiers. An unauthenticated,     remote attacker can exploit this, via a crafted SNMP     object, to cause a denial of service or to execute     arbitrary code. (CVE-2016-4071)

  - An invalid memory write error exists in PHP when     handling the path of phar file names that allows an     attacker to have an unspecified impact. (CVE-2016-4072)

  - A remote code execution vulnerability exists in PHP in     phar_object.c due to improper handling of zero-length     uncompressed data. An unauthenticated, remote attacker     can exploit this, via a specially crafted TAR, ZIP, or     PHAR file, to cause a denial of service condition or the     execution of arbitrary code. (CVE-2016-4342)

  - A remote code execution vulnerability exists in PHP in     the phar_make_dirstream() function within file     ext/phar/dirstream.c due to improper handling of     ././@LongLink files. An unauthenticated, remote attacker     can exploit this, via a specially crafted TAR file, to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-4343)

  - A cross-site scripting (XSS) vulnerability exists due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2016-4393)

  - An unspecified HTTP Strict Transport Security (HSTS)     bypass vulnerability exists that allows authenticated,     remote attackers to disclose sensitive information.
    (CVE-2016-4394)

  - A remote code execution vulnerability exists due to an     overflow condition in the mod_smh_config.so library     caused by improper validation of user-supplied input     when parsing the admin-group parameter supplied to the     /proxy/SetSMHData endpoint. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to cause a denial of service condition or the     execution of arbitrary code. (CVE-2016-4395)

  - A remote code execution vulnerability exists due to an     overflow condition in the mod_smh_config.so library     caused by improper validation of user-supplied input     when parsing the TKN parameter supplied to the     /Proxy/SSO endpoint. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to cause a denial of service condition or the     execution of arbitrary code. (CVE-2016-4396)

  - An out-of-bounds read error exists in PHP in the     php_str2num() function in bcmath.c when handling     negative scales. An unauthenticated, remote attacker can     exploit this, via a crafted call, to cause a denial of     service condition or the disclosure of memory contents.
    (CVE-2016-4537)

  - A flaw exists in PHP the bcpowmod() function in bcmath.c     due to modifying certain data structures without     considering whether they are copies of the _zero_,
    _one_, or _two_ global variables. An unauthenticated,     remote attacker can exploit this, via a crafted call, to     cause a denial of service condition. (CVE-2016-4538)

  - A flaw exists in PHP in the xml_parse_into_struct()     function in xml.c when handling specially crafted XML     contents. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2016-4539)

  - Multiple out-of-bounds read errors exist in PHP within     file ext/intl/grapheme/grapheme_string.c when handling     negative offsets in the zif_grapheme_stripos() and     zif_grapheme_strpos() functions. An unauthenticated,     remote attacker can exploit these issues to cause a     denial of service condition or disclose memory contents.
    (CVE-2016-4540, CVE-2016-4541)

  - A flaw exists in PHP in the exif_process_IFD_TAG()     function in exif.c due to improper construction of     spprintf arguments. An unauthenticated, remote attacker     can exploit this, via crafted header data, to cause an     out-of-bounds read error, resulting in a denial of     service condition or the disclosure of memory contents.
    (CVE-2016-4542)

  - A flaw exists in PHP in the exif_process_IFD_in_JPEG()     function in exif.c due to improper validation of IFD     sizes. An unauthenticated, remote attacker can exploit     this, via crafted header data, to cause an out-of-bounds     read error, resulting in a denial of service condition     or the disclosure of memory contents. (CVE-2016-4543)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', in the Apache Tomcat, Apache HTTP Server, and     PHP components due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. A remote attacker can exploit this, via a     crafted 'Proxy' header in an HTTP request, to redirect     an application's internal HTTP traffic to an arbitrary     proxy server where it may be observed or manipulated.
    (CVE-2016-5385, CVE-2016-5387, CVE-2016-5388)
