///////////////////////////////

SQL injection vulnerability:-
============================== 
in file product.php data from GET parameter 'productbycat' is not getting filter before passing into SQL query and hence rising SQL Injection vulnerability
---------------------
$getallproduct="select * from purchase where status='enable' and catid=$_GET[productbycat] order by id desc";
---------------------
POC

http://127.0.0.1/ecommercemajor/product.php?productbycat=SQLI


Authentication Bypass:-
============================== 
file index.php under directory __admin has SQL injection vulnerability
parameter username and password suppliedin post parameter for checking valid admin username and password is not getting filter before passing into SQL query which arise authentication bypass issue.
vulnerable code is 
-------------------
	if(isset($_POST[login]))
		{
$check="select * from adminlogin where username='$_POST[username]' and password='$_POST[username]'";
			$checkresult=mysql_query($check);
			$checkcount=mysql_num_rows($checkresult);
			if($checkcount>0)
				{	
					$checkrow=mysql_fetch_array($checkresult);
					$_SESSION[adminname]=$checkrow[adminname];
					$_SESSION[adminloginstatus]="success";
					echo "<script>window.location='home.php';</script>";
				}
--------------------

Sybase Advantage Server 10.0.0.3 is vulnerable; other versions may also be affected. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/35886.zip ####################################################################### Luigi Auriemma Application: Sybase Advantage Server http://www.sybase.com/products/databasemanagement/advantagedatabaseserver Versions: <= 10.0.0.3 Platforms: Windows, NetWare, Linux Bug: off-by-one Exploitation: remote, versus server Date: 27 Jun 2011 (found 29 Oct 2010) Author: Luigi Auriemma e-mail: aluigi@autistici.org web: aluigi.org ####################################################################### 1) Introduction 2) Bug 3) The Code 4) Fix ####################################################################### =============== 1) Introduction =============== From vendor's website: "Advantage Database Server is a full-featured, easily embedded, client-server, relational database management system that provides you with Indexed Sequential Access Method (ISAM) table-based and SQL-based data access." ####################################################################### ====== 2) Bug ====== By default the Advantage server (ADS process) listens on the UDP and TCP ports 6262 and optionally is possible to specify also a so called "internet port" for non-LAN connections. The problem is enough unusual and affects the code that handles a certain type of packets on the UDP port. In short the server does the following: - it uses memcpy to copy the data from the packet into a stack buffer of exactly 0x2b8 bytes (handled as 0x2b9 bytes) - later this data is handled as a string but no final NULL byte delimiter is inserted - there is also an off-by-one bug since one byte overwrites the lower 8bit value of a saved element (a stack pointer 017bff??) - after this buffer are located some pushed elements and obviously the return address of the function - it calls the OemToChar API that changes some bytes of the buffer (like those major than 0x7f) till it reaches a 0x00 that "luckily" is after the return address - so also the return address gets modified, exactly from 0084cb18 to 00e42d18 that ironically is a valid stack frame somewhat related to the starting of the service - the data inside this stack address doesn't seems changeable from outside and has tons of 0x00 bytes that in this case act like NOPs till the zone around 00ebf05b where are located some pushed elements - the EBX register contains two bytes of the attacker's data and EBP points to such data the following is a resume of these operations: 017BF66B 61 61 61 61 61 61 61 61 61 61 61 61 61 61 FF 7B aaaaaaaaaaaaaa�{ 017BF67B 01 99 26 C1 71 BC F6 7B 01 18 CB 84 00 00 00 00 .�&�q��{..˄.... |---------| original return address 0084B81D |.

Now for exploiting this vulnerability would be required the presence of a "jmp ebp" or "call ebp" or a sequence of instructions with a similar result in the 00ebf05b zone which looks like an enough rare event. I have not tested the Linux and NetWare platforms so I don't know if the problem exists also there and if there are more chances of exploiting it. ####################################################################### =========== 3) The Code =========== http://aluigi.org/testz/udpsz.zip http://aluigi.org/poc/ads_crc.zip udpsz -C 0012 -L ads_crc.dll -b 0x61 SERVER 6262 0x592 ####################################################################### ====== 4) Fix ====== No fix.

WordPress Plugin Pixarbay Images 2.3 - Multiple Vulnerabilities

HACKER · %s · %s

Mogwai Security Advisory MSA-2015-01 ---------------------------------------------------------------------- Title: WP Pixarbay Images Multiple Vulnerabilities Product: Pixarbay Images (Wordpress Plugin) Affected versions: 2.3 Impact: high Remote: yes Product link: https://wordpress.org/plugins/pixabay-images/ Reported: 14/01/2015 by: Hans-Martin Muench (Mogwai, IT-Sicherheitsberatung Muench) Vendor's Description of the Software: ---------------------------------------------------------------------- Pixabay Images is a WordPress plugin that let's you pick CC0 public domain pictures from Pixabay and insert them with just a click anywhere on your blog. The images are safe to use, and paying attribution or linking back to the source is not required. Business recommendation: ---------------------------------------------------------------------- Update to version 2.4 Vulnerability description: ---------------------------------------------------------------------- 1) Authentication bypass The plugin does not correctly check if the user is logged in. Certain code can be called without authentication 2) Arbitrary file upload The plugin code does not validate the host in the provided download URL, which allows to upload malicious files, including PHP code. 3) Path Traversal Certain values are not sanitized before they are used in a file operation. This allows to store files outside of the "download" folder. 4) Cross Site Scripting (XSS) The generated author link uses unsanitized user values which can be abused for Cross Site Scripting (XSS) attacks.

Cisco Ironport Appliances - Privilege Escalation

HACKER · %s · %s

/* Cisco Ironport Appliances Privilege Escalation Vulnerability Vendor: Cisco Product webpage: http://www.cisco.com Affected version(s): Cisco Ironport ESA - AsyncOS 8.5.5-280 Cisco Ironport WSA - AsyncOS 8.0.5-075 Cisco Ironport SMA - AsyncOS 8.3.6-0 Date: 22/05/2014 Credits: Glafkos Charalambous CVE: Not assigned by Cisco Disclosure Timeline: 19-05-2014: Vendor Notification 20-05-2014: Vendor Response/Feedback 27-08-2014: Vendor Fix/Patch 24-01-2015: Public Disclosure Description: Cisco Ironport appliances are vulnerable to authenticated "admin" privilege escalation. By enabling the Service Account from the GUI or CLI allows an admin to gain root access on the appliance, therefore bypassing all existing "admin" account limitations. The vulnerability is due to weak algorithm implementation in the password generation process which is used by Cisco to remotely access the appliance to provide technical support. Vendor Response: As anticipated, this is not considered a vulnerability but a security hardening issue. As such we did not assign a CVE however I made sure that this is fixed on SMA, ESA and WSA. The fix included several changes such as protecting better the algorithm in the binary, changing the algorithm itself to be more robust and enforcing password complexity when the administrator set the pass-phrase and enable the account. [SD] Note: Administrative credentials are needed in order to activate the access to support representative and to set up the pass-phrase that it is used to compute the final password. [GC] Still Admin user has limited permissions on the appliance and credentials can get compromised too, even with default password leading to full root access. [SD] This issue is tracked for the ESA by Cisco bug id: CSCuo96011 for the SMA by Cisco bug id: CSCuo96056 and for WSA by Cisco bug id CSCuo90528 Technical Details: By logging in to the appliance using default password "ironport" or user specified one, there is an option to enable Customer Support Remote Access. This option can be found under Help and Support -> Remote Access on the GUI or by using the CLI console account "enablediag" and issuing the command service. Enabling this service requires a temporary user password which should be provided along with the appliance serial number to Cisco techsupport for remotely connecting and authenticating to the appliance. Having a temporary password and the serial number of the appliance by enabling the service account, an attacker can in turn get full root access as well as potentially damage it, backdoor it, etc. PoC: Enable Service Account ---------------------- root@kali:~# ssh -lenablediag 192.168.0.158 Password: Last login: Sat Jan 24 15:47:07 2015 from 192.168.0.163 Copyright (c) 2001-2013, Cisco Systems, Inc.

RedaxScript 2.1.0 - Privilege Escalation

HACKER · %s · %s

# Exploit Title: Privilege Escalation in RedaxScript 2.1.0 # Date: 11-05-2014 # Exploit Author: shyamkumar somana # Vendor Homepage: http://redaxscript.com/ # Version: 2.1.0 # Tested on: Windows 8 #Privilege Escalation in RedaxScript 2.1.0 RedaxScript 2.1.0 suffers from a privilege Escalation vulnerability. The issue occurs because the application fails to properly implement access controls. The application also fails to perform proper sanity checks on the user supplied input before processing it. These two flaws led to a vertical privilege escalation. This can be achieved by a simply tampering the parameter values. An attacker can exploit this issue to gain elevated privileges to the application. *Steps to reproduce the instance:* · login as a non admin user · Go to account and update the account. · intercept the request and add “*groups[]=1*” to the post data and submit the request · Log out of the application and log in again. You can now browse the application with admin privileges. This vulnerability was addressed in the following commit. https://github.com/redaxmedia/redaxscript/commit/bfe146f98aedb9d169ae092b49991ed1b3bc0860?diff=unified *Timeline*: 09-26-2014: Issue identified 09-27-2014: Discussion with the vendor 10-27-2014: Issue confirmed 11-05-2014: Patch released.

The JSP that accepts the upload does not handle correctly '../' sequences, which can be abused to write in the file system. Authentication is needed to exploit this vulnerability, but this module will attempt to login using the default credentials for the administrator and guest accounts. Alternatively you can provide a pre-authenticated cookie or a username / password combo. For IT360 targets enter the RPORT of the ServiceDesk instance (usually 8400). All versions of ServiceDesk prior v9 build 9031 (including MSP but excluding v4), AssetExplorer, SupportCenter and IT360 (including MSP) are vulnerable. At the time of release of this module, only ServiceDesk v9 has been fixed in build 9031 and above.

En este post vamos a estar resolviendo el laboratorio de PortSwigger: “Blind OS command injection with out-of-band interaction”.
Para resolver el laboratorio tenemos que ocasionar una búsqueda DNS al servidor público de Burp Suite (burpcollaborator.net). Para ello, haremos uso de un Blind OS Command Injection que se encuentra en la función de feedback.
Como podemos observar, hay unos cuantos campos a rellenar. Por lo que vamos a rellenarlos:
Ahora, antes de enviar el feedback. Preparamos el burp suite para que reciba las peticiones:
Con esto listo, enviamos el feedback para captar la petición:
Esta es la petición que se envía al servidor cuando se envía feedback. Para tratar con ella, la enviamos al repeater pulsando Ctrl R:
Una vez en el repeater, podemos observar como una petición válida simplemente obtiene una respuesta de estado 200 y no mucho más.
Sin embargo, entre todos los parámetros que se están enviando, vamos a intentar ver si podemos ejecutar un comando en alguno de ellos, y, con ello, realizar una búsqueda DNS al servidor de burp suite:
Al realizar esta petición si actualizamos la web, nos daremos cuenta de que hemos resuelto el reto:
En este caso, sí que es cierto, que lo mejor para realizar los retos estilo «out-of-band» es contar con el Burp Suite PRO para poder hacer uso de la característica de Burp Collaborator client:
De hecho, el siguiente y último reto de OS Command Injection (al menos a fecha de enero de 2021) no se puede resolver si no es que con Burp Suite PRO 😥.
