Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| 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 |
