CVE-2024-52318 - Apache Tomcat XSS Vulnerability in Generated JSPs# CVE-2024-52318
🚨🚨CVE-2024-52318 - Apache Tomcat XSS Vulnerability in Generated JSPs🚨🚨
Overview
CVE-2024-52318 is a crosssite scripting (XSS) vulnerability in Apache Tomcat, which arises from improperly released resources in generated JavaServer Pages (JSPs). This issue, introduced by a prior improvement (fix 69333), causes some JSP tags to fail in escaping output as expected. This can allow attackers to inject malicious scripts into web pages, potentially compromising user data or hijacking user sessions.
Affected Versions
The following versions of Apache Tomcat are vulnerable:
Version Series Affected Versions
Apache Tomcat 11.0 Versions prior to 11.0.1
Apache Tomcat 10.1 Versions prior to 10.1.33
Apache Tomcat 9.0 Versions prior to 9.0.97
Exploitability
Attack Vector
How the Exploit Works:
Attackers can exploit this vulnerability by injecting malicious payloads into vulnerable JSPs. The failure to properly escape output may result in the execution of injected scripts when users access the affected pages.
Potential Impact:
Theft of sensitive user information, such as cookies and session tokens.
Execution of unauthorized actions in the context of a user's session (e.g., CSRF attacks).
Disruption of data integrity and overall system security.
Mitigation
Upgrade
To resolve this vulnerability, upgrade to a patched version of Apache Tomcat:
Apache Tomcat 11.0.1 or later.
Apache Tomcat 10.1.33 or later.
Apache Tomcat 9.0.97 or later.
Best Practices for JSP Development
1. Ensure all JSP outputs are explicitly escaped to prevent XSS vulnerabilities.
2. Regularly review and audit JSP configurations and tag library usage.
3. Implement a Content Security Policy (CSP) to mitigate the impact of any injected scripts.
