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.

  - 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)

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 Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r23. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL :

  - A flaw exists in the SSLv2 implementation,     specifically in the get_client_master_key() function     within file s2_srvr.c, due to accepting a nonzero     CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an     arbitrary cipher. A man-in-the-middle attacker can     exploit this to determine the MASTER-KEY value and     decrypt TLS ciphertext by leveraging a Bleichenbacher     RSA padding oracle. (CVE-2016-0703)

  - A flaw exists in the SSLv2 oracle protection mechanism,     specifically in the get_client_master_key() function     within file s2_srvr.c, due to incorrectly overwriting     MASTER-KEY bytes during use of export cipher suites.
    A remote attackers can exploit this to more easily     decrypt TLS ciphertext by leveraging a Bleichenbacher     RSA padding oracle. (CVE-2016-0704)

  - A NULL pointer dereference flaw exists in the     BN_hex2bn() and BN_dec2bn() functions. A remote attacker     can exploit this to trigger a heap corruption, resulting     in the execution of arbitrary code. (CVE-2016-0797)

  - A flaw exists that allows a cross-protocol     Bleichenbacher padding oracle attack known as DROWN     (Decrypting RSA with Obsolete and Weakened eNcryption).
    This vulnerability exists due to a flaw in the Secure     Sockets Layer Version 2 (SSLv2) implementation, and it     allows captured TLS traffic to be decrypted. A     man-in-the-middle attacker can exploit this to decrypt     the TSL connection by utilizing previously captured     traffic and weak cryptography along with a series of     specially crafted connections to an SSLv2 server that     uses the same private key. (CVE-2016-0800)

  - A heap buffer overflow condition exists 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 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)

  - A remote code execution vulnerability exists in the     ASN.1 encoder due to an underflow condition that occurs     when attempting to encode the value zero represented as     a negative integer. An unauthenticated, remote attacker     can exploit this to corrupt memory, resulting in the     execution of arbitrary code. (CVE-2016-2108)

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

All users of Red Hat JBoss Web Server 2.1.0 on Red Hat Enterprise Linux 6 are advised to upgrade to Red Hat JBoss Web Server 2.1.1. The JBoss server process must be restarted for this update to take effect.

Security Fix(es) :

* It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5387)

* An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncodeUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105)

* An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncryptUpdate() function of OpenSSL parsed very large amounts of input data.

Security Fix(es) :

  - A flaw was found in the way OpenSSL encoded certain     ASN.1 data structures. An attacker could use this flaw     to create a specially crafted certificate which, when     verified or re-encoded by OpenSSL, could cause it to     crash, or execute arbitrary code using the permissions     of the user running an application compiled against the     OpenSSL library. (CVE-2016-2108)

  - Two integer overflow flaws, leading to buffer overflows,     were found in the way the EVP_EncodeUpdate() and     EVP_EncryptUpdate() functions of OpenSSL parsed very     large amounts of input data. A remote attacker could use     these flaws to crash an application using OpenSSL or,     possibly, execute arbitrary code with the permissions of     the user running that application. (CVE-2016-2105,     CVE-2016-2106)

  - It was discovered that OpenSSL leaked timing information     when decrypting TLS/SSL and DTLS protocol encrypted     records when the connection used the AES CBC cipher     suite and the server supported AES-NI. A remote attacker     could possibly use this flaw to retrieve plain text from     encrypted packets by using a TLS/SSL or DTLS server as a     padding oracle. (CVE-2016-2107)

  - Several flaws were found in the way BIO_*printf     functions were implemented in OpenSSL. Applications     which passed large amounts of untrusted data through     these functions could crash or potentially execute code     with the permissions of the user running such an     application. (CVE-2016-0799, CVE-2016-2842)

  - A denial of service flaw was found in the way OpenSSL     parsed certain ASN.1-encoded data from BIO (OpenSSL's     I/O abstraction) inputs. An application using OpenSSL     that accepts untrusted ASN.1 BIO input could be forced     to allocate an excessive amount of data. (CVE-2016-2109)

According to its banner, the version of OpenSSL on the remote host is 1.0.1 prior to 1.0.1t, or 1.0.2 prior to 1.0.2h. It is therefore affected by the following vulnerabilities :

 - A flaw exists in 'crypto/asn1/a_d2i_fp.c', which is triggered during the handling of large length fields in ASN.1 BIO. This may allow a remote attacker to exhaust memory resources, potentially crashing a process linked against the library.
 - A flaw exists in the 'aesni_cbc_hmac_sha1_cipher()' function in 'crypto/evp/e_aes_cbc_hmac_sha1.c' and 'aesni_cbc_hmac_sha256_cipher()' function in 'crypto/evp/e_aes_cbc_hmac_sha256.c'. The issue is triggered when a connection uses an AES CBC cipher and AES-NI is supported by the server. This may allow a MitM (Man-in-the-Middle) attacker to conduct a padding oracle attack to potentially decrypt traffic.
 - A flaw in the 'X509_NAME_oneline()' function in 'crypto/x509/x509_obj.c' that is triggered when handling overly long ASN1 strings. This may allow a remote attacker to potentially disclose arbitrary stack memory contents.
 - An overflow condition in the 'EVP_EncryptUpdate()' function in 'crypto/evp/evp_enc.c' is triggered when handling a large amount of input data after a previous call to the same function with a partial block. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially resulting in the execution of arbitrary code.
 - An overflow condition in the 'EVP_EncodeUpdate()' function in 'crypto/evp/encode.c' is triggered when handling a large amount of input data. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially resulting in the execution of arbitrary code.

Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of data.
