CVE-2020-9055 describes a stored Cross-Site Scripting (XSS) vulnerability affecting the Versiant LYNX Customer Service Portal. This vulnerability allows a local, authenticated attacker to inject malicious JavaScript code that is then stored and displayed to other users. Versions 3.5.2 are affected, and a patch is available in version 3.5.3.
Successful exploitation of CVE-2020-9055 could allow an attacker to execute arbitrary JavaScript code within the context of a victim's browser session. This could lead to a variety of malicious actions, including website redirection to phishing sites, stealing session cookies to impersonate users, and exfiltrating sensitive information displayed within the portal. The stored nature of the XSS means the injected script persists, potentially affecting multiple users who view the compromised content. While the CVSS score is LOW, the potential for session hijacking and data theft warrants immediate attention.
CVE-2020-9055 was publicly disclosed on March 30, 2020. No public proof-of-concept exploits are currently known. The vulnerability is not listed on the CISA KEV catalog. Given the relatively low CVSS score and lack of public exploits, the probability of active exploitation is considered low, but vigilance is still advised.
Organizations utilizing the Versiant LYNX Customer Service Portal version 3.5.2, particularly those with local authenticated users accessing sensitive data through the portal, are at risk. Environments with weak input validation or lacking WAF protection are especially vulnerable.

The primary mitigation for CVE-2020-9055 is to upgrade the LYNX Customer Service Portal to version 3.5.3 or later. If immediate upgrading is not possible, consider implementing strict input validation and output encoding on all user-supplied data within the portal. Web Application Firewalls (WAFs) configured to detect and block XSS payloads can provide an additional layer of defense. Regularly review and sanitize stored data to identify and remove any potentially malicious scripts. After upgrading, confirm the vulnerability is resolved by attempting to inject a simple JavaScript payload and verifying it is not executed.
