Technical Details
The vulnerability stems from improper sanitization of user-supplied input within the Retro platform. Specifically, the application fails to adequately escape or validate data before rendering it in a web page. This allows an attacker to inject malicious JavaScript code via a crafted input, such as within a user profile, a product description, or a comment section. When another user views the page containing the injected script, the script executes within their browser, potentially granting the attacker access to sensitive information or control over the user’s session.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns this vulnerability a score of 6.1 (Medium). While the impact isn’t considered critical, the exploitability and potential consequences warrant immediate attention. A successful exploit could lead to:
- Account takeover
- Session hijacking
- Data theft (e.g., credentials, personal information)
- Defacement of the website
- Redirection to malicious websites
Possible Impact
