Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Organizations should immediately review and restrict URL redirection functionality within Dell Unity interfaces, implementing strict validation and allowlisting of redirect targets. Until official patches are released, consider deploying web application firewalls (WAFs) with rules to detect and block suspicious redirect patterns. Educate users about phishing risks and encourage verification of URLs before clicking links related to Dell Unity portals. Monitor network traffic for unusual redirection attempts and implement multi-factor authentication (MFA) to reduce session hijacking impact. Regularly audit and update endpoint security solutions to detect phishing payloads. Coordinate with Dell support for timely patch deployment once available and apply security best practices for storage management systems. Additionally, isolate Dell Unity management interfaces from public internet access where possible to limit exposure.

Description

Dell Unity, version(s) 5.4 and prior, contain(s) an URL Redirection to Untrusted Site ('Open Redirect') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to a targeted application user being redirected to arbitrary web URLs. The vulnerability could be leveraged by attackers to conduct phishing attacks that cause users to divulge sensitive information. Exploitation may allow for session theft.

Impact

The vulnerability can lead to significant security breaches including credential theft, unauthorized access, and potential compromise of sensitive enterprise storage environments. Phishing attacks leveraging this open redirect can deceive users into divulging confidential information or downloading malware, impacting organizational confidentiality and integrity. Session theft can result in attackers hijacking user sessions, leading to further unauthorized actions within the affected system. Given Dell Unity's deployment in critical storage infrastructure worldwide, exploitation could disrupt business operations and data availability. The ease of exploitation without authentication and the potential for widespread phishing campaigns elevate the threat level, especially in sectors reliant on secure data storage such as finance, healthcare, and government. Organizations failing to address this vulnerability risk reputational damage, regulatory penalties, and operational downtime.

CWE-601URL Redirection to Untrusted Site ('Open Redirect') (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
