CVE-2023-50345 is an Open Redirect vulnerability identified in HCL Software's DRYiCE MyXalytics product, specifically affecting versions 5.9, 6.0, and 6.1. An Open Redirect vulnerability (CWE-601) occurs when a web application accepts a user-controlled input that specifies a link to an external site and redirects the user to that site without sufficient validation. This flaw can be exploited by attackers to craft malicious URLs that appear to originate from a trusted domain but redirect victims to malicious websites. Such redirections can facilitate phishing attacks, social engineering, or delivery of malware by exploiting user trust in the legitimate domain. The CVSS v3.1 base score for this vulnerability is 3.7, indicating a low severity level. The vector string (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) shows that the attack can be performed remotely over the network without privileges or user interaction, but requires high attack complexity. The impact is limited to confidentiality with no impact on integrity or availability. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is published and reserved as of December 2023 and January 2024 respectively. Given the nature of the vulnerability, the primary risk is that users of DRYiCE MyXalytics could be redirected to malicious sites, potentially exposing them to phishing or other malicious activities. However, the lack of required user interaction and high attack complexity reduce the immediate risk level.

For European organizations using HCL DRYiCE MyXalytics, this vulnerability poses a moderate risk primarily to end users who might be redirected to malicious sites. While the direct impact on the organization's systems is limited, the reputational damage and potential data exposure from successful phishing campaigns could be significant. Organizations in sectors with high regulatory scrutiny, such as finance, healthcare, and government, may face compliance risks if user data is compromised following a phishing attack leveraging this vulnerability. The low CVSS score suggests limited direct technical impact, but the indirect consequences through social engineering could lead to credential theft or unauthorized access. Since the vulnerability does not affect system integrity or availability, operational disruption is unlikely. However, the presence of this vulnerability could be exploited as part of a broader attack chain targeting European enterprises that rely on DRYiCE MyXalytics for analytics and automation, especially if attackers combine it with other vulnerabilities or social engineering tactics.

1. Implement strict validation and sanitization of all URL parameters used for redirection within DRYiCE MyXalytics to ensure only trusted domains are allowed. 2. Employ allowlisting for redirect URLs to prevent arbitrary external redirects. 3. Monitor and audit web server logs for unusual redirect patterns that could indicate exploitation attempts. 4. Educate users about the risks of clicking on suspicious links, even if they appear to originate from trusted domains. 5. Apply web application firewalls (WAF) rules that detect and block open redirect attempts targeting the application. 6. Coordinate with HCL Software for timely patches or updates addressing this vulnerability and plan for prompt deployment once available. 7. Consider implementing multi-factor authentication (MFA) to reduce the impact of potential credential compromise resulting from phishing. 8. Review and update incident response plans to include scenarios involving phishing attacks leveraging open redirect vulnerabilities.
