CVE-2024-1780: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in setriosoft BizCalendar Web
The BizCalendar Web plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 1.1.0.25 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
AI Analysis
Technical Summary
The BizCalendar Web WordPress plugin suffers from a reflected XSS vulnerability via the 'tab' parameter due to improper neutralization of input during web page generation. This allows unauthenticated attackers to inject and execute arbitrary scripts in users' browsers if they can convince users to interact with malicious links. The vulnerability affects all versions up to 1.1.0.25. The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity. No patch or official remediation has been published by the vendor as of the latest information.
Potential Impact
Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website, potentially allowing attackers to steal user session data, perform actions on behalf of users, or deliver malicious payloads. The impact is limited to confidentiality and integrity with no availability impact. The vulnerability requires user interaction and does not require authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling the BizCalendar Web plugin or restricting access to affected functionality. Additionally, applying web application firewall (WAF) rules to detect and block malicious input targeting the 'tab' parameter may help mitigate risk. Monitor vendor channels for updates and apply patches promptly once available.
