From this webpage screenshot, the following key information about the vulnerability can be obtained: 1. Vulnerability Description: - Vulnerability Name: Error page lacks escaping, leading to potential XSS on import of malicious project - Severity: Moderate - Publisher: wetneb - Vulnerability ID: GHSA-j8hp-f2mj-586g - Publication Date: Yesterday 2. Affected Versions: - Affected Versions: <3.8.3 - Fixed Version: 3.8.3 3. Description: - Overview: The built-in "Something went wrong!" error page includes an error message and stack trace, but does not escape HTML tags. If an attacker can reliably generate an error message under their control, it may lead to injection. - Attack Path: The attacker may need to convince the victim to import a malicious file, such as GHSA-m88m-crr9-jvqq, which may be difficult. However, external plugins may add their own error-handling calls. 4. Details: - Exploitation: The Velocity template is rendered via the function, which includes and variables that are not escaped. - Mitigation: It is recommended to use Guava’s HTML escaper to escape messages and stack traces. - Impact: If an attacker can convince a victim to import a malicious project, arbitrary JavaScript may be executed in the victim’s browser. 5. Exploitation Example: - Exploit Code: Use OpenRefine’s “Import project” feature to import a specific URL (or upload a file). - Exploit Result: A JavaScript alert is displayed in the victim’s browser. 6. Impact: - Attackers can execute arbitrary JavaScript, provided the victim is tricked into importing a malicious project. Attackers can perform any action that the user can perform. This information helps understand the nature, scope of impact, and exploitation method of the vulnerability.
