Synopsis
The remote web server is affected by multiple vulnerabilities.
Description
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)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to HP System Management Homepage (SMH) version 7.6 or later.
