This cross-site scripting vulnerability exists within the Joomlaskin JS Multi Hotel plugin for WordPress, specifically in the delete_img.php file. The flaw affects versions 2.2.1 and earlier, making it a significant security concern for WordPress installations that utilize this hotel management plugin. The vulnerability stems from improper input validation and output encoding of the path parameter, which allows malicious actors to inject arbitrary web scripts or HTML content into the application's response.
The technical implementation of this vulnerability occurs when the application processes user-supplied input through the path parameter without adequate sanitization or encoding measures. This parameter is directly incorporated into the web page response without proper context-aware encoding, creating an environment where attacker-controlled data can be executed as script within the victim's browser context. The vulnerability classifies under CWE-79 as a failure to sanitize or encode user-controllable data before it is used in web output, which is a fundamental principle of secure web application development.
From an operational impact perspective, this XSS vulnerability enables remote attackers to execute malicious scripts in the context of authenticated users' browsers, potentially leading to session hijacking, credential theft, or unauthorized administrative actions. Attackers could craft malicious URLs containing script payloads that would execute when victims navigate to affected pages, particularly those involving image deletion functionality. The vulnerability is particularly dangerous because it affects a hotel management plugin, which often requires administrative privileges and may handle sensitive guest data, making the potential impact on data confidentiality and integrity substantial.
The attack vector for this vulnerability aligns with ATT&CK technique T1566.001, specifically the use of malicious HTML content in web applications. The vulnerability enables attackers to establish persistent malicious presence within the target environment, potentially allowing for more sophisticated attacks such as credential harvesting or lateral movement within the WordPress installation. Given that this is a plugin vulnerability rather than a core WordPress issue, the attack surface is limited to installations that have specifically installed and configured this particular hotel management solution.
Recommended mitigations include immediate patching of the affected plugin to version 2.2.2 or later, which should contain proper input validation and output encoding measures. Organizations should also implement proper content security policies to limit script execution capabilities within the affected application context. Additionally, administrators should conduct thorough security audits of all installed WordPress plugins to identify similar vulnerabilities and ensure that input validation is consistently applied across all user-controllable parameters. Network-based mitigations such as web application firewalls can provide additional protection layers, though they should not replace proper code-level fixes. Regular security monitoring and vulnerability scanning should be implemented to detect similar issues in other third-party components and prevent exploitation of similar input validation flaws.
