DescriptionCVE.org

A flaw has been found in westboy CicadasCMS up to 2431154dac8d0735e04f1fd2a3c3556668fc8dab. Impacted is the function Search of the file org/springframework/cache/support/AbstractCacheManager.java. This manipulation of the argument s causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been published and may be used. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Reflected cross-site scripting in westboy CicadasCMS allows remote unauthenticated attackers to inject arbitrary JavaScript into a victim's browser via the unvalidated 's' search parameter in the Search function. All code up to and including commit 2431154dac8d0735e04f1fd2a3c3556668fc8dab is affected, with no patch released as of analysis - the vendor has not responded to the responsible disclosure. A publicly available exploit exists (CVSS E:P confirmed), elevating the urgency despite the moderate CVSS base score of 4.3.

Technical ContextAI

CicadasCMS is a Java-based content management system built on the Spring Framework (org.springframework.cache.support.AbstractCacheManager). The vulnerability resides in the Search function within AbstractCacheManager.java, where user-supplied input to the 's' query argument is incorporated into the HTTP response without adequate output encoding or sanitization. CWE-79 (Improper Neutralization of Input During Web Page Generation - 'Cross-site Scripting') identifies the root cause as a failure to neutralize user-controlled data before it is rendered in a web page, enabling script injection. The affected CPE is cpe:2.3:a:westboy:cicadascms:*:*:*:*:*:*:*:*, encompassing all tracked versions of the product.

RemediationAI

No vendor-released patch has been identified at time of analysis; the vendor has not responded to the disclosure reported via https://gitee.com/westboy/CicadasCMS/issues/IJKWOH. Organizations running CicadasCMS should apply compensating controls immediately. Deploy a Web Application Firewall (WAF) rule to block or sanitize requests containing script-injection patterns in the 's' search parameter - note this may generate false positives on legitimate search queries containing angle brackets. If the search functionality is non-critical, disabling or restricting access to the Search endpoint eliminates the attack surface entirely but degrades site usability. Operators should monitor the Gitee repository at https://gitee.com/westboy/CicadasCMS/ for any upstream commit that addresses output encoding in AbstractCacheManager.java and apply it promptly. Given the unresponsive vendor posture, consider whether continued use of this CMS is acceptable without an active maintainer.
