CVE-2023-45471 in Search Server
Summary
by MITRE • 10/25/2023
The QAD Search Server is vulnerable to Stored Cross-Site Scripting (XSS) in versions up to, and including, 1.0.0.315 due to insufficient checks on indexes. This makes it possible for unauthenticated attackers to create a new index and inject a malicious web script into its name, that will execute whenever a user accesses the search page.

The QAD Search Server vulnerability represents a critical stored cross-site scripting flaw that undermines the security posture of organizations relying on this search infrastructure. This vulnerability exists within versions up to and including 1.0.0.315, where the system fails to properly validate and sanitize user input during index creation processes. The flaw stems from inadequate input validation mechanisms that allow malicious actors to inject malicious scripts into index names, creating a persistent threat vector that can affect all users interacting with the search functionality. The vulnerability's classification as a stored XSS issue means that the malicious payload remains embedded within the application's database or storage system, executing each time affected users access the search page regardless of their authentication status.
The technical implementation of this vulnerability exploits the lack of proper sanitization checks on index names during the creation process. When an attacker creates a new index with malicious script content in the index name field, the application stores this data without adequate filtering or encoding. This stored data is then rendered unfiltered when users access the search interface, leading to script execution in the context of the victim's browser. The vulnerability specifically targets the indexing functionality where user-provided data is directly incorporated into the application's response without proper security controls. According to CWE standards, this represents a CWE-79: Cross-site Scripting vulnerability, with the stored variant specifically classified under CWE-80. The flaw operates at the application layer where input validation fails to properly sanitize user-supplied data before it is processed and displayed.
The operational impact of this vulnerability extends beyond simple script execution, creating a persistent threat that can be leveraged for various malicious activities. Unauthenticated attackers can exploit this vulnerability to steal session cookies, perform unauthorized actions on behalf of users, or redirect victims to malicious websites. The vulnerability's ability to affect unauthenticated users makes it particularly dangerous as it eliminates the need for prior access credentials or privileged accounts. Attackers can craft malicious index names containing scripts that can harvest sensitive information from user browsers or establish persistent backdoors through techniques like beaconing to external command and control servers. This vulnerability directly violates the principle of least privilege and can lead to complete compromise of user sessions and potential data exfiltration. The attack surface is broad as any user who accesses the search functionality becomes a potential victim, making this a significant concern for organizations with multiple users interacting with the search server.
Organizations should implement immediate mitigations including input validation and sanitization of all user-provided data, particularly during index creation processes. The recommended approach involves implementing proper output encoding and input filtering mechanisms that prevent script execution in index names and other user-controllable fields. Security patches should be applied immediately to upgrade to versions that address this vulnerability, while network segmentation and monitoring can provide additional layers of protection. The implementation of web application firewalls and content security policies can help detect and block malicious payloads, while regular security assessments should verify that input validation mechanisms are properly configured. According to ATT&CK framework, this vulnerability maps to T1566.001: Phishing with Social Engineering and T1059.001: Command and Scripting Interpreter, highlighting the potential for initial access through phishing and subsequent execution of malicious code. Regular security training for administrators and users can help prevent exploitation through social engineering tactics, while comprehensive logging and monitoring should be implemented to detect suspicious index creation activities. The vulnerability serves as a reminder of the critical importance of input validation in web applications and the need for robust security controls throughout the application lifecycle.
