Summary
by MITRE
On Apache JSPWiki, up to version 2.11.0.M4, a carefully crafted plugin link invocation could trigger an XSS vulnerability on Apache JSPWiki, related to the Page Revision History, which could allow the attacker to execute javascript in the victim's browser and get some sensitive information about the victim.

The vulnerability CVE-2019-10087 represents a cross-site scripting flaw in Apache JSPWiki versions up to 2.11.0.M4 that specifically targets the Page Revision History functionality. This security weakness arises from insufficient input validation and output encoding mechanisms within the wiki's plugin invocation system. The vulnerability occurs when users interact with carefully crafted plugin links that are designed to exploit the revision history feature, creating a pathway for malicious javascript code execution in the victim's browser context.
The technical implementation of this vulnerability stems from improper sanitization of user-supplied data within the revision history display mechanism. When Apache JSPWiki processes plugin links in the context of page revision history, it fails to adequately escape or validate the input parameters that control plugin execution. This allows attackers to inject malicious javascript payloads through crafted plugin invocation URLs that are then rendered in the victim's browser. The vulnerability is classified under CWE-79 as a failure to sanitize user input, specifically manifesting as a cross-site scripting vulnerability that enables arbitrary code execution within the user's browsing session.
The operational impact of this vulnerability extends beyond simple script execution to include potential data exfiltration and session hijacking capabilities. Attackers can leverage this flaw to steal sensitive information such as cookies, session tokens, and potentially access restricted wiki content. The vulnerability is particularly concerning because it operates within the legitimate revision history functionality that users expect to be safe, making it more likely to be exploited in targeted attacks. The attack vector requires minimal user interaction, typically involving the victim clicking on a malicious link that triggers the vulnerable revision history display.
Mitigation strategies for CVE-2019-10087 should prioritize immediate patching to versions 2.11.0.M5 and later, which contain the necessary input validation and output encoding fixes. Organizations should implement comprehensive input validation for all plugin invocation parameters and ensure proper HTML escaping of dynamic content in revision history displays. Security teams should also consider implementing content security policies that restrict script execution within wiki environments and monitor for suspicious plugin link patterns. The vulnerability aligns with ATT&CK technique T1566.001 for initial access through malicious links and T1059.007 for execution through script-based attacks. Additionally, regular security assessments should verify that all wiki plugins properly handle user input and that revision history features do not inadvertently expose sensitive data through improper output encoding mechanisms.
