Vulnerability Note VU#294272

ReadyDesk contains multiple vulnerabilities

Original Release date: 16 Aug 2016 | Last revised: 16 Aug 2016


ReadyDesk, version 9.1 and possibly others, contains SQL injection, path traversal, hard-coded cryptographic key, and arbitrary file upload vulnerabilities that may be leveraged to expose sensitive data and execute arbitrary code in the context of the vulnerable software.


ReadyDesk is a help desk ticketing web application designed to facilitate business internal or business to customer interactions.

CWE-89: Improper Neutralization of Special Elements used in a SQL Command ('SQL Injection') - CVE-2016-5048

The user name field of http://<IP>/readydesk/chat/staff/default.aspx fails to properly escape single quote characters, or ', provided as field input. Through error-based, blind SQL injection attacks, a remote, unauthenticated attacker may obtain full database contents, including user passwords which are stored as SHA1 hashes.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory - CVE-2016-5049

The SESID parameter of requests to http://<IP>/readydesk/chat/openattach.aspx is vulnerable to directory traversal and may be exploited to read arbitrary files on affected systems when combined with the FNAME parameter. For instance, to download SQL_Config.aspx, an attacker would make a request to:


CWE-321: Use of Hard-coded Cryptographic Key - CVE-2016-5683

SQL Server user credentials stored in SQL_Config.aspx are encrypted using a hard-coded cryptographic key found in ReadyDesk.dll. An attacker capable of obtaining the encrypted password can easily decrypt it for use in further attacks.

CWE-434: Unrestricted Upload of File with Dangerous Type - CVE-2016-5050

Files uploaded via http://<IP>/readydesk/chat/sendfile.aspx are not properly validated, allowing for arbitrary upload of files with a dangerous type. A remote, unauthenticated attacker could execute arbitrary code by uploading and making a request to a specially crafted aspx page.

The CVE score below describes CVE-2016-5050.


A remote, unauthenticated attacker can obtain sensitive database information, read arbitrary files, and execute arbitrary code in the context of the vulnerable software.


The CERT/CC is currently unaware of a practical solution to these problems. A vendor advisory for version 9.2 states that it contains "Critical Security Updates," though details are not provided and it is unknown whether any of the vulnerabilities described above are addressed.
