CVE-2025-32430: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in xwiki xwiki-platform
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 4.2-milestone-3 through 16.4.7, 16.5.0-rc-1 through 16.10.5 and 17.0.0-rc-1 through 17.2.2, two templates contain reflected XSS vulnerabilities, allowing an attacker to execute malicious JavaScript code in the context of the victim's session by getting the victim to visit an attacker-controlled URL. This permits the attacker to perform arbitrary actions using the permissions of the victim. This issue is fixed in versions 16.4.8, 16.10.6 and 17.3.0-rc-1. To workaround the issue, manually patch the WAR with the same changes as the original patch.
AI Analysis
Technical Summary
CVE-2025-32430 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the XWiki Platform, a widely used generic wiki platform that provides runtime services for applications built on top of it. This vulnerability affects multiple versions of the xwiki-platform, specifically versions from 4.2-milestone-3 up to but not including 16.4.8, versions 16.5.0-rc-1 up to but not including 16.10.6, and versions 17.0.0-rc-1 up to but not including 17.3.0-rc-1. The root cause is improper neutralization of input during web page generation, categorized under CWE-79. Two templates in these versions contain reflected XSS flaws, which allow an attacker to craft malicious URLs that, when visited by a victim, execute arbitrary JavaScript code within the victim’s browser context. This execution leverages the victim’s session and permissions, enabling the attacker to perform unauthorized actions as the victim. The vulnerability requires no authentication and no privileges, but does require user interaction in the form of visiting a maliciously crafted URL. The issue has been addressed in versions 16.4.8, 16.10.6, and 17.3.0-rc-1, with a manual patch workaround available by applying the same changes as the official patch to the WAR file. The CVSS v4.0 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and high scope impact due to the ability to perform actions with the victim’s permissions. No known exploits are currently reported in the wild, but the vulnerability’s nature and ease of exploitation make it a significant risk if left unpatched.
Potential Impact
For European organizations, the impact of this vulnerability can be substantial, especially for those relying on XWiki Platform for internal documentation, collaboration, or application runtime services. Successful exploitation can lead to session hijacking, unauthorized actions performed under the victim’s identity, and potential data leakage or manipulation. This can compromise confidentiality and integrity of sensitive corporate information and disrupt business processes. Since XWiki is often used in enterprise environments, including government, education, and private sectors, attackers could leverage this vulnerability to escalate privileges or move laterally within networks. The reflected XSS nature means phishing or social engineering campaigns could be used to lure users into clicking malicious links, increasing the attack surface. The medium severity score indicates a moderate but non-trivial risk, with potential for significant operational impact if exploited at scale or against high-privilege users.
Mitigation Recommendations
European organizations should prioritize upgrading affected XWiki Platform instances to the fixed versions 16.4.8, 16.10.6, or 17.3.0-rc-1 as soon as possible. If immediate upgrade is not feasible, applying the manual patch to the WAR file to replicate the official fix is recommended. Additionally, organizations should implement strict input validation and output encoding in any custom templates or extensions to prevent injection of malicious scripts. Deploying Web Application Firewalls (WAFs) with rules to detect and block reflected XSS payloads targeting XWiki URLs can provide temporary protection. User awareness training to recognize suspicious URLs and phishing attempts is also critical to reduce the risk of exploitation via social engineering. Monitoring logs for unusual URL access patterns and anomalous user actions within XWiki can help detect attempted or successful exploitation. Finally, organizations should review and minimize user permissions within XWiki to limit the potential damage from compromised accounts.
