HotelDruid version 2.3.0 contains multiple cross-site scripting vulnerabilities that affect several parameters across different php files. The vulnerability specifically targets the nsextt, cambia1, mese_fine, origine, and anno parameters within creaprezzi.php, tabella3.php, personalizza.php, and visualizza_tabelle.php. These parameters are susceptible to injection attacks that allow malicious actors to execute arbitrary javascript code in the context of a victim's browser session. The vulnerability falls under CWE-79 which defines cross-site scripting as a weakness that occurs when an application includes untrusted data in a new web page without proper validation or escaping, or when it reuses a static HTML page without sufficient escaping. The attack vector is particularly concerning as it affects multiple core functionality files of the hotel management system, potentially enabling attackers to hijack user sessions, deface web pages, or redirect users to malicious sites. The operational impact extends beyond simple data corruption as it can compromise the entire user authentication system and potentially allow for privilege escalation attacks.
The technical implementation of this vulnerability stems from inadequate input sanitization and output encoding practices within the HotelDruid application. When user-supplied parameters are directly incorporated into dynamic web page content without proper validation or escaping mechanisms, the system becomes vulnerable to malicious payload injection. The affected parameters are likely processed through GET requests and integrated into HTML output without appropriate sanitization filters. This creates a persistent vulnerability that can be exploited by attackers who craft malicious URLs containing javascript payloads. The ATT&CK framework categorizes this as a web application vulnerability exploitation technique under the T1190 category for exploit public-facing application, with potential for T1071.1001 for application layer protocol and T1566 for phishing with malicious attachments. The vulnerability affects the application's integrity and availability, potentially disrupting hotel reservation processes and compromising sensitive guest data.
Mitigation strategies for this vulnerability should include immediate implementation of input validation and output encoding measures across all affected php files. The system requires comprehensive parameter sanitization to prevent javascript injection attempts, with all user-supplied data being properly escaped before being rendered in web pages. Security patches should address the specific parameters mentioned in the vulnerability description, ensuring that nsextt, cambia1, mese_fine, origine, and anno are validated against expected data types and ranges. Organizations should implement Content Security Policy headers to limit script execution and prevent unauthorized code injection. Additionally, regular security audits should be conducted to identify similar vulnerabilities in other application components. The remediation process should include updating to the latest stable version of HotelDruid or implementing custom input validation routines that align with OWASP secure coding practices. Network monitoring should be enhanced to detect anomalous traffic patterns that may indicate exploitation attempts, while access controls should be reviewed to ensure that only authorized users can modify critical system parameters.
