It can allow or disallow visitors from defined countries to (parts of) the content of the website. The settings of the plugin can be exported or imported using its backup functionality. An authorized user can import preconfigured settings of the plugin by uploading a zip file. After the uploading process, files in the uploaded zip file are extracted one by one. During the extraction process, existence of a file is checked. If the file exists, it is deleted without any security control by only considering the name of the extracted file. This behavior leads to “Zip Slip” vulnerability. Zip Slip can cause damage by overwriting configuration files or other sensitive resources. In this finding, An attacker can exploit this vulnerability and the behavior of the extraction process, to delete an arbitrary file in the server. For doing this, it is enough to upload a zip file containing a file that is named as the path of a file which is desired to be deleted. The details of the discovery are given below. # Steps To Reproduce: 1. Install and activate the iQ Block Country plugin. 2. Create a test file in the vulnerable system: (e.g. /var/www/html/test.txt) 3. Create a zip file containing a file named as ../../../../test.txt. Absolute path at the end of this process will be: /var/www/html/wp-content/uploads/2022/01/../../../../test.txt 4. Go back to the Wordpress, visit Settings > iQ Block Country > Import/Export tab. 5. Click the “Browse” button and choose the zip file which is created in the Step 3. 6. Click the “Restore settings” button. 7. “Invalid file” message will be appeared but nevermind the message. Check whether the test.txt file is deleted or not. </code></pre>

ADVISORY INFORMATION ======================= Product: SAP Knowledge Warehouse Vendor URL: https://help.sap.com/viewer/816f1f952d244bbf9dd5063e2a0e66b0/7.5.21/en-US/4dc9605e4a9d6522e10000000a15822b.html Type: Cross-Site Scripting [CWE-79] Date found: 2021-09-21 Date published: 2022-03-17 CVSSv3 Score: 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) CVE: CVE-2021-42063 2. CREDITS ========== This vulnerability was discovered and researched by Julien Ahrens from RCE Security. 3. VERSIONS AFFECTED ==================== SAP Knowledge Warehouse - versions 7.30, 7.31, 7.40, 7.50 4. INTRODUCTION =============== The SAP Knowledge Warehouse (SAP KW) is the SAP Solution for all the material used in training, documentation and handbooks. (from the vendor's homepage) 5. VULNERABILITY DETAILS ======================== The endpoint at /SAPIrExtHelp is vulnerable to an unauthenticated reflected Cross-Site Scripting vulnerability when user-supplied input to the URI is processed by the web application. Since the application does not properly validate and sanitize this input, it is possible to place arbitrary script code onto the same page. The following Proof-of-Concept triggers this vulnerability: https://localhost/SAPIrExtHelp/random/%22%3e%3c%53%56%47%20%4f%4e%4c%4f%41%44%3d%26%23%39%37%26%23%31%30%38%26%23%31%30%31%26%23%31%31%34%26%23%31%31%36%28%26%23%78%36%34%26%23%78%36%66%26%23%78%36%33%26%23%78%37%35%26%23%78%36%64%26%23%78%36%35%26%23%78%36%65%26%23%78%37%34%26%23%78%32%65%26%23%78%36%34%26%23%78%36%66%26%23%78%36%64%26%23%78%36%31%26%23%78%36%39%26%23%78%36%65%29%3e.asp 6. RISK ======= To successfully exploit this vulnerability an unauthenticated or authenticated user must be tricked into visiting an arbitrary website / link. The vulnerability can be used to temporarily embed arbitrary script code into the context of the web interface, which offers a wide range of possible attacks such as redirecting the user to a malicious page, spoofing content on the page or attacking the browser and its plugins. 7. SOLUTION =========== Update SAP Knowledge Warehouse to the latest version. 8.

There is no secure coding practice or filtering of input or sanitization of output. Third-party attackers who can reach the server can make HTTP Post requests writing arbitrary JS code into the Slaves.txt file.
