Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (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.

description This module is a port of the Equation Group ETERNALBLUE exploit, part of the FuzzBunch toolkit released by Shadow Brokers. There is a buffer overflow memmove operation in Srv!SrvOs2FeaToNt. The size is calculated in Srv!SrvOs2FeaListSizeToNt, with mathematical error where a DWORD is subtracted into a WORD. The kernel pool is groomed so that overflow is well laid-out to overwrite an SMBv1 buffer. Actual RIP hijack is later completed in srvnet!SrvNetWskReceiveComplete. This exploit, like the original may not trigger 100% of the time, and should be run continuously until triggered. It seems like the pool will get hot streaks and need a cool down period before the shells rain in again. The module will attempt to use Anonymous login, by default, to authenticate to perform the exploit. If the user supplies credentials in the SMBUser, SMBPass, and SMBDomain options it will use those instead. On some systems, this module may cause system instability and crashes, such as a BSOD or a reboot. This may be more likely with some payloads. id MSF:EXPLOIT/WINDOWS/SMB/MS17_010_ETERNALBLUE last seen 2020-06-09 modified 2020-04-21 published 2017-12-14 references - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-0143

Please read my exploit for Windows 7/2008 at https://gist.github.com/worawit/bd04bad3cd231474763b873df081c09a because the trick for exploit is almost the same \- The exploit use heap of HAL for placing fake struct (address 0xffffffffffd00e00) and shellcode (address 0xffffffffffd01000). On Windows 8 and Wndows 2012, the NX bit is set on this memory page. Need to disable it before controlling RIP. \- The exploit is likely to crash a target when it failed \- The overflow is happened on nonpaged pool so we need to massage target nonpaged pool. \- If exploit failed but target does not crash, try increasing 'GroomAllocations' value (at least 5) \- See the code and comment for exploit detail. Disable NX method: \- The idea is from "Bypassing Windows 10 kernel ASLR (remote) by Stefan Le Berre" (see link in reference) \- The exploit is also the same but we need to trigger bug twice \- First trigger, set MDL.MappedSystemVa to target pte address \- Write '\x00' to disable the NX flag \- Second trigger, do the same as Windows 7 exploit \- From my test, if exploit disable NX successfully, I always get code execution id MSF:EXPLOIT/WINDOWS/SMB/MS17_010_ETERNALBLUE_WIN8 last seen 2020-06-04 modified 2019-11-02 published 2018-06-15 references - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-0143

Microsoft has also released emergency patches for Windows operating systems that are no longer supported, including Windows XP, 2003, and 8.
