CVE-2022-37927 is an Open Redirect vulnerability identified in Hewlett Packard Enterprise's (HPE) OneView Global Dashboard (OVGD) product, affecting versions prior to 2.7. The vulnerability is classified under CWE-601, which pertains to improper validation of URLs leading to redirection to untrusted sites. Specifically, this flaw allows an attacker to craft a malicious URL that appears to originate from a legitimate HPE OVGD instance but redirects users to an external, potentially malicious domain. The vulnerability has a CVSS 3.1 base score of 6.1 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and low impact on confidentiality and integrity (C:L, I:L) but no impact on availability (A:N). The scope change implies that the vulnerability affects components beyond the initially vulnerable component, potentially impacting other system components or users. Exploitation requires user interaction, typically by convincing a user to click a crafted link. While no known exploits are reported in the wild, the vulnerability could be leveraged in phishing campaigns or social engineering attacks to redirect users to malicious websites, potentially leading to credential theft, malware installation, or further exploitation. The vulnerability does not directly compromise system integrity or availability but can be a stepping stone for more complex attacks. The lack of an official patch link suggests that remediation may require upgrading to version 2.7 or later, where the vulnerability is presumably fixed. The vulnerability affects a network management and monitoring tool used in enterprise environments to provide centralized visibility and control over IT infrastructure, making it a valuable target for attackers aiming to compromise organizational security through indirect means.

For European organizations using HPE OneView Global Dashboard, this vulnerability poses a moderate risk primarily through social engineering vectors. Attackers could exploit the open redirect to craft convincing phishing URLs that appear to originate from trusted internal dashboards, increasing the likelihood of successful credential harvesting or malware delivery. Given that OVGD is used to monitor and manage critical IT infrastructure, successful exploitation could indirectly lead to unauthorized access if attackers leverage stolen credentials or deliver payloads via redirected sites. Although the vulnerability itself does not allow direct system compromise or denial of service, the potential for lateral movement or escalation through subsequent attacks increases the overall risk profile. Organizations in sectors with high reliance on HPE OVGD for infrastructure management—such as telecommunications, finance, manufacturing, and government—may face increased exposure. Additionally, the scope change in the CVSS vector indicates that the impact could extend beyond the immediate application, potentially affecting integrated systems or users. The requirement for user interaction means that security awareness and training are critical factors in mitigating risk. The absence of known exploits in the wild reduces immediate threat levels but does not eliminate the possibility of future exploitation, especially as threat actors often weaponize such vulnerabilities in targeted campaigns.

To mitigate this vulnerability, European organizations should prioritize upgrading HPE OneView Global Dashboard to version 2.7 or later, where the open redirect issue is resolved. In the absence of an official patch, organizations can implement the following specific measures: 1) Review and restrict URL parameters that control redirection within OVGD to ensure they only allow internal or whitelisted domains, possibly through custom web application firewall (WAF) rules. 2) Implement strict Content Security Policy (CSP) headers to limit the domains to which browsers can navigate or load resources, reducing the impact of malicious redirects. 3) Enhance email and web filtering solutions to detect and block phishing attempts that exploit this vulnerability by scanning for suspicious URLs referencing OVGD. 4) Conduct targeted user awareness training emphasizing the risks of clicking on unexpected links, especially those purporting to originate from internal dashboards. 5) Monitor logs for unusual redirect patterns or access attempts involving OVGD URLs to detect potential exploitation attempts early. 6) If feasible, isolate the OVGD interface behind VPN or zero-trust network access controls to limit exposure to external users. These measures, combined with timely patching, will reduce the attack surface and limit the potential for successful exploitation.
