The vulnerability identified as CVE-2019-10077 represents a cross-site scripting weakness in Apache JSPWiki versions ranging from 2.9.0 through 2.11.0.M3. This security flaw specifically manifests through the processing of InterWiki links, which are used within the wiki system to create references to external web resources. The vulnerability stems from insufficient input validation and output encoding mechanisms within the InterWiki link handling functionality, creating an environment where maliciously crafted links can execute unauthorized scripts in the context of other users' browsers. This particular weakness falls under the CWE-79 category of Cross-Site Scripting, specifically representing a stored XSS variant where the malicious payload is persisted within the wiki system and executed when other users view the affected pages.
The technical exploitation of this vulnerability requires an attacker to craft a malicious InterWiki link containing embedded script code that gets stored within the JSPWiki database or configuration. When other users navigate to pages containing this malicious link, their browsers execute the embedded JavaScript code, which can then access session cookies, perform actions on behalf of the user, or redirect to malicious sites. The vulnerability's impact extends beyond simple script execution as it enables session hijacking capabilities, allowing attackers to impersonate legitimate users and gain unauthorized access to their wiki accounts. This particular flaw demonstrates a critical failure in the application's security architecture where user-provided content is not properly sanitized before being rendered to end users.
The operational impact of CVE-2019-10077 is significant for organizations relying on Apache JSPWiki for collaborative documentation and knowledge management. Attackers could leverage this vulnerability to steal user sessions, access confidential information, modify wiki content, or establish persistent access points within the organization's internal documentation systems. The vulnerability's presence in multiple versions of JSPWiki indicates a widespread exposure risk across numerous deployments, particularly affecting organizations that may not have implemented regular security updates. This weakness creates an attack vector that can be exploited without requiring special privileges or advanced technical skills, making it particularly dangerous in environments where wiki systems serve as central repositories for sensitive business information.
Organizations should immediately implement mitigations including upgrading to Apache JSPWiki versions 2.11.0.M4 or later, which contain the necessary security patches addressing this vulnerability. Additionally, administrators should implement strict input validation for InterWiki link parameters and consider implementing Content Security Policy headers to limit script execution capabilities within the wiki environment. The mitigation strategy should also include regular security assessments of wiki configurations and user access controls to minimize potential damage from any exploitation attempts. This vulnerability highlights the importance of maintaining up-to-date software versions and implementing comprehensive input validation mechanisms as part of defense-in-depth strategies, aligning with ATT&CK technique T1213 for credential access through web application vulnerabilities.
