Detailsinfo

A vulnerability classified as critical has been found in Horizon Business Services Caterease up to 24.0.1.2405 (Hospitality Software). Affected is the function xp_cmdshell of the component SQL Server. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue in Horizon Business Services Inc. Caterease 16.0.1.1663 through 24.0.1.2405 and possibly later versions, allows a remote attacker to perform command line execution through SQL Injection due to improper neutralization of special elements used in an OS command.

The bug was discovered 05/04/2024. The weakness was released by Calvin Star (Skelet4r) with jTag Labs as security advisory (VulDB). The public release was coordinated with the vendor. Caterease is vulnerable to remote code execution through SQL Injection. The improper neutralization of special elements in SQL commands allows attackers to inject and execute arbitrary commands on the SQL server via xp_cmdshell. By exploiting this vulnerability, an attacker can craft malicious SQL queries that are executed with high-level privileges, enabling them to perform unauthorized actions on the server. This includes reading or modifying sensitive data, creating or deleting database objects, and even executing system-level commands. This vulnerability is traded as CVE-2024-38882 since 06/21/2024. The exploitability is told to be easy. The attack can only be initiated within the local network. The exploitation doesn't require any form of authentication. Technical details and a private exploit are known. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 02/25/2026). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

A private exploit has been developed by Skelet4r in Python. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 90 days. During that time the estimated underground price was around . Although an exploit is not currently publicly available, a proof-of-concept exploit has been developed by Skelet4r and jTag Labs to confirm the existence of this vulnerability within the Caterease application. This exploit was created for internal use only and is not being released publicly. To exploit this vulnerability, an attacker can utilize TCP packet injection techniques to inject custom packets into the communication stream between the client application and the server. By crafting TDS payloads within these injected packets, the attacker can execute malicious SQL queries that enable xp_cmdshell, leading to the execution of arbitrary OS commands on the SQL server. This method leverages the improper neutralization of special elements in SQL commands, resulting in unauthorized command execution on the server.

The best possible mitigation is suggested to be Workaround. The vulnerability will be addressed with the following lines of code:

USE Caterease;

EXEC sp_droprolemember 'db_owner', 'Caterease';
EXEC sp_addrolemember 'db_datareader', 'Caterease';
EXEC sp_addrolemember 'db_datawriter', 'Caterease';
To mitigate the risk of OS Command Injection in Caterease Software, you can adjust the permissions of the default SQL user, 'Caterease,' within the SQL Server. The default SQL user currently has the db_owner role, which grants full administrative privileges, including the ability to enable xp_cmdshell—a stored procedure that allows the execution of shell commands directly from SQL Server. This can be exploited by attackers to execute arbitrary commands on the server's operating system. To reduce this risk, follow these steps: 1. Remove the Caterease SQL User from the db_owner Role: By removing the Caterease SQL user from the db_owner role, you revoke its administrative privileges, preventing the execution of potentially harmful commands on the SQL Server. 2. Assign the db_datawriter and db_datareader Roles: Add the Caterease SQL user to the db_datawriter and db_datareader roles. These roles provide the necessary permissions for the user to perform essential read and write operations within the Caterease database without granting administrative rights. By implementing this workaround, the Caterease SQL user will retain the ability to perform necessary database operations required by the Caterease application, while the risk of OS Command Injection is significantly reduced. The user will no longer have the ability to enable xp_cmdshell or execute other administrative actions on the SQL Server, thereby preventing attackers from exploiting this vulnerability to run commands on the operating system.
