Knowage is vulnerable to blind server-side request forgery (SSRF)

Knowage is an open source analytics and business intelligence suite. Prior to version 8.1.37, there is a blind server-side request forgery vulnerability. The vulnerability allows attackers to send requests to arbitrary hosts/paths. Since the attacker is not able to read the response, the impact of this vulnerability is limited. However, an attacker should be able to leverage this vulnerability to scan the internal network. This issue has been patched in version 8.1.37.

Knowage Contains a Remote Code Execution Vulnerability

Knowage is an open source analytics and business intelligence suite. Versions 8.1.26 and below are vulnerable to Remote Code Exection through using an unsafe org.apache.commons.jxpath.JXPathContext in MetaService.java service. This issue is fixed in version 8.1.27.

Knowage vulnerable to server-side request forgery

Knowage is an open source analytics and business intelligence suite. Prior to version 8.1.37, Knowage is vulnerable to server-side request forgery. The vulnerability allows attackers to send requests to arbitrary hosts/paths. Since the attacker is not able to read the response, the impact of this vulnerability is limited. However, an attacker could be able to leverage this vulnerability to scan the internal network. This issue has been patched in version 8.1.37.

Improper Neutralization of Alternate XSS Syntax in Knowage-Server

Knowage is an open source suite for modern business analytics alternative over big data systems. KnowageLabs / Knowage-Server starting with the 6.x branch and prior to versions 7.4.22, 8.0.9, and 8.1.0 is vulnerable to cross-site scripting because the `XSSRequestWrapper::stripXSS` method can be bypassed. Versions 7.4.22, 8.0.9, and 8.1.0 contain patches for this issue. There are no known workarounds.

Knowage-Server vulnerable to Path traversal in download functionalities

Knowage is the professional open source suite for modern business analytics over traditional sources and big data systems. The endpoint `_/knowage/restful-services/dossier/importTemplateFile_` allows authenticated users to download template hosted on the server. However, starting in the 6.x.x branch and prior to version 8.1.8, the application does not sanitize the `_templateName_ `parameter allowing an attacker to use `*../*` in it, and escaping the directory the template are normally placed and download any file from the system. This vulnerability allows a low privileged attacker to exfiltrate sensitive configuration file. This issue has been patched in Knowage version 8.1.8.

Knowage Server vulnerable to path traversal via upload functionality

Knowage is an open source analytics and business intelligence suite. Starting in the 6.x.x branch and prior to version 8.1.8, the endpoint `/knowage/restful-services/dossier/importTemplateFile` allows authenticated users to upload `template file` on the server, but does not need any authorization to be reached. When the JSP file is uploaded, the attacker just needs to connect to `/knowageqbeengine/foo.jsp` to gain code execution on the server. By exploiting this vulnerability, an attacker with low privileges can upload a JSP file to the `knowageqbeengine` directory and gain code execution capability on the server. This issue has been patched in Knowage version 8.1.8.

Query injection in Knowage server

Knowage is an open source suite for business analytics. The application often use user supplied data to create HQL queries without prior sanitization. An attacker can create specially crafted HQL queries that will break subsequent SQL queries generated by the Hibernate engine. The endpoint `_/knowage/restful-services/2.0/documents/listDocument_` calls the `_countBIObjects_` method of the `_BIObjectDAOHibImpl_` object with the user supplied `_label_` parameter without prior sanitization. This can lead to SQL injection in the backing database. Other injections have been identified in the application as well. An authenticated attacker with low privileges could leverage this vulnerability in order to retrieve sensitive information from the database, such as account credentials or business information. This issue has been addressed in version 8.1.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Knowage-Server vulnerable to account validation bypass

Knowage is an open source analytics and business intelligence suite. Starting in version 6.0.0 and prior to version 8.1.8, an attacker can register and activate their account without having to click on the link included in the email, allowing them access to the application as a normal user. This issue has been patched in version 8.1.8.

Knowage Suite 7.3 is vulnerable to Stored Client-Side Template Injection in '/knowage/restful-services/signup/update' via the 'name' parameter.

Knowage Suite 7.3 is vulnerable to unauthenticated reflected cross-site scripting (XSS). An attacker can inject arbitrary web script in '/servlet/AdapterHTTP' via the 'targetService' parameter.

Knowage Suite 7.3 is vulnerable to Stored Cross-Site Scripting (XSS). An attacker can inject arbitrary web script in '/knowage/restful-services/documentnotes/saveNote' via the 'nota' parameter.

Knowage Suite 7.3 is vulnerable to Stored Cross-Site Scripting (XSS). An attacker can inject arbitrary web script in '/knowage/restful-services/signup/update' via the 'surname' parameter.

Knowage Suite before 7.4 is vulnerable to cross-site scripting (XSS). An attacker can inject arbitrary external script in '/knowagecockpitengine/api/1.0/pages/execute' via the 'SBI_HOST' parameter.

A stored HTML injection vulnerability exists in Knowage Suite version 7.1. An attacker can inject arbitrary HTML in "/restful-services/2.0/analyticalDrivers" via the 'LABEL' and 'NAME' parameters.

Knowage Suite before 7.4 is vulnerable to reflected cross-site scripting (XSS). An attacker can inject arbitrary web script in /restful-services/publish via the 'EXEC_FROM' parameter that can lead to data leakage.

A SQL injection vulnerability in Knowage Suite version 7.1 exists in the documentexecution/url analytics driver component via the 'par_year' parameter when running a report.

In Knowage through 6.1.1, an authenticated user who accesses the datasources page will gain access to any data source credentials in cleartext, which includes databases.

In Knowage through 6.1.1, the sign up page does not invalidate a valid CAPTCHA token. This allows for CAPTCHA bypass in the signup page.
