Impact:
Exploitability:
CWE CWE-200
CAPEC
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

    description According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.32. It is, therefore, affected by multiple vulnerabilities : - The Perl-Compatible Regular Expressions (PCRE) library is affected by multiple vulnerabilities related to the handling of regular expressions, subroutine calls, and binary files. A remote attacker can exploit these to cause a denial of service, obtain sensitive information, or have other unspecified impact.

A remote attacker can exploit this to bypass restrictions. - A flaw exists in file ext/standard/streamsfuncs.c in the stream_get_meta_data() function due to a failure to restrict writing user-supplied data to fields not already set. A remote attacker can exploit this to falsify the output of the function, resulting in the insertion of malicious metadata. - A type confusion error exists in file ext/wddx/wddx.c in the php_wddx_pop_element() function when deserializing WDDX packets. A remote attacker can exploit this to have an unspecified impact. - A flaw exists in file ext/phar/phar_object.c in the PharFileInfo::getContent() method due to the use of uninitialized memory causing improper validation of user-supplied input. A remote attacker can exploit this to corrupt memory, resulting in a denial of service or the execution of arbitrary code. - A NULL pointer dereference flaw exists in file ext/phar/tar.c in the phar_tar_setupmetadata() function when parsing metadata from a crafted TAR file. A remote attacker can exploit this to cause a denial of service. - An integer overflow condition exists in file ext/standard/iptc.c in the iptcembed() function due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. - An overflow condition exists in file ext/phar/tar.c in the phar_parse_tarfile() function due to improper validation of user-supplied input when decompressing TAR files. A remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-2554) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

These security issues were fixed : - CVE-2014-8964: Heap-based buffer overflow in PCRE allowed remote attackers to cause a denial of service (crash) or have other unspecified impact via a crafted regular expression, related to an assertion that allows zero repeats (bsc#906574). - CVE-2015-2325: Heap buffer overflow in compile_branch() (bsc#924960). - CVE-2015-3210: Heap buffer overflow in pcre_compile2() / compile_regex() (bsc#933288) - CVE-2015-3217: PCRE Library Call Stack Overflow Vulnerability in match() (bsc#933878). - CVE-2015-5073: Library Heap Overflow Vulnerability in find_fixedlength() (bsc#936227). - bsc#942865: heap overflow in compile_regex() - CVE-2015-8380: The pcre_exec function in pcre_exec.c mishandled a // pattern with a \01 string, which allowed remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror (bsc#957566). - CVE-2015-2327: PCRE mishandled certain patterns with internal recursive back references, which allowed remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror (bsc#957567). - bsc#957598: Various security issues - CVE-2015-8381: Heap Overflow in compile_regex() (bsc#957598). - CVE-2015-8382: Regular Expression Uninitialized Pointer Information Disclosure Vulnerability (ZDI-CAN-2547)(bsc#957598). - CVE-2015-8383: Buffer overflow caused by repeated conditional group(bsc#957598). - CVE-2015-8384: Buffer overflow caused by recursive back reference by name within certain group(bsc#957598). - CVE-2015-8385: Buffer overflow caused by forward reference by name to certain group(bsc#957598). - CVE-2015-8386: Buffer overflow caused by lookbehind assertion(bsc#957598). - CVE-2015-8387: Integer overflow in subroutine calls(bsc#957598). - CVE-2015-8388: Buffer overflow caused by certain patterns with an unmatched closing parenthesis(bsc#957598). - CVE-2015-8389: Infinite recursion in JIT compiler when processing certain patterns(bsc#957598). - CVE-2015-8390: Reading from uninitialized memory when processing certain patterns(bsc#957598). - CVE-2015-8391: Some pathological patterns causes pcre_compile() to run for a very long time(bsc#957598). - CVE-2015-8392: Buffer overflow caused by certain patterns with duplicated named groups(bsc#957598). - CVE-2015-8393: Information leak when running pcgrep -q on crafted binary(bsc#957598). - CVE-2015-8394: Integer overflow caused by missing check for certain conditions(bsc#957598). - CVE-2015-8395: Buffer overflow caused by certain references(bsc#957598). - CVE-2015-2328: PCRE mishandled the /((?(R)a|(?1)))+/ pattern and related patterns with certain recursion, which allowed remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression (bsc#957600). - CVE-2016-1283: The pcre_compile2 function in pcre_compile.c in PCRE mishandled certain patterns with named subgroups, which allowed remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression (bsc#960837). - CVE-2016-3191: The compile_branch function in pcre_compile.c in pcre2_compile.c mishandled patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which allowed remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted regular expression (bsc#971741). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description This release fixes these vulnerabilies: CVE-2015-8383, CVE-2015-8386, CVE-2015-8387, CVE-2015-8389, CVE-2015-8390, CVE-2015-8391, CVE-2015-8393, CVE-2015-8394. It also fixes compiling comments with auto-callouts, compiling expressions with negated classes in UCP mode, compiling expressions with an isolated \E between an item and its qualifier with auto-callouts, a crash in regexec() if REG_STARTEND option is set and pmatch argument is NULL, a stack overflow when formatting a 32-bit integer in pcregrep tool, compiling expressions with an empty \Q\E sequence between an item and its qualifier with auto-callouts, compiling expressions with global extended modifier that is disabled by local no-extended option at the start of the expression just after a whitespace, a possible crash in pcre_copy_named_substring() if a named substring has number greater than the space in the ovector, a buffer overflow when compiling an expression with named groups with a group that reset capture numbers, and a crash in pcre_get_substring_list() if the use of \K caused the start of the match to be earlier than the end. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id PHP_5_6_18.NASL
    description According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.18. It is, therefore, affected by multiple vulnerabilities : - The Perl-Compatible Regular Expressions (PCRE) library is affected by multiple vulnerabilities related to the handling of regular expressions, subroutine calls, and binary files. A remote attacker can exploit these to cause a denial of service, obtain sensitive information, or have other unspecified impact. (CVE-2015-8383, CVE-2015-8386, CVE-2015-8387, CVE-2015-8389, CVE-2015-8390, CVE-2015-8391, CVE-2015-8393, CVE-2015-8394) - A flaw exists in file ext/standard/exec.c in the escapeshellcmd() and escapeshellarg() functions due to the program truncating NULL bytes in strings. A remote attacker can exploit this to bypass restrictions. - A flaw exists in file ext/standard/streamsfuncs.c in the stream_get_meta_data() function due to a failure to restrict writing user-supplied data to fields not already set. A remote attacker can exploit this to falsify the output of the function, resulting in the insertion of malicious metadata. - A type confusion error exists in file ext/wddx/wddx.c in the php_wddx_pop_element() function when deserializing WDDX packets. A remote attacker can exploit this to have an unspecified impact. - A flaw exists in file ext/phar/phar_object.c in the PharFileInfo::getContent() method due to the use of uninitialized memory causing improper validation of user-supplied input. A remote attacker can exploit this to corrupt memory, resulting in a denial of service or the execution of arbitrary code. - A NULL pointer dereference flaw exists in file ext/phar/tar.c in the phar_tar_setupmetadata() function when parsing metadata from a crafted TAR file. A remote attacker can exploit this to cause a denial of service. - An integer overflow condition exists in file ext/standard/iptc.c in the iptcembed() function due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. - An overflow condition exists in file ext/phar/tar.c in the phar_parse_tarfile() function due to improper validation of user-supplied input when decompressing TAR files. A remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-2554) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
