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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.

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 2026-10-25.

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.

What to do

AI-suggested

To mitigate CVE-2024-28287, organizations should: 1) Implement strict validation and sanitization of the returnUrl parameter on both client and server sides to ensure only trusted URLs are accepted. 2) Employ an allowlist approach restricting redirection targets to known safe domains. 3) Where possible, avoid using open redirect parameters or replace them with token-based redirection mechanisms that verify the legitimacy of the redirect destination. 4) Educate users to recognize suspicious URLs and avoid clicking on untrusted links, especially those received via email or messaging platforms. 5) Monitor web traffic for unusual redirection patterns that may indicate exploitation attempts. 6) Engage with the software vendor for patches or updates addressing this vulnerability and apply them promptly once available. 7) Use web application firewalls (WAFs) to detect and block malicious redirection attempts. 8) Conduct regular security assessments and penetration testing focusing on URL redirection and input validation controls.

Description

A DOM-based open redirection in the returnUrl parameter of INSTINCT UI Web Client 6.5.0 allows attackers to redirect users to malicious sites via a crafted URL.

Impact

The primary impact of CVE-2024-28287 is on user confidentiality and integrity. Attackers can leverage the open redirection to redirect users to malicious websites that may host phishing pages or malware, potentially leading to credential compromise or further exploitation. This can undermine user trust and lead to unauthorized access to sensitive systems if credentials or session tokens are stolen. While availability is not directly affected, the reputational damage and potential data breaches can have significant operational and financial consequences. Organizations relying on INSTINCT UI Web Client 6.5.0, particularly in sectors such as government, critical infrastructure, and enterprise environments, face increased risk of targeted phishing campaigns exploiting this vulnerability. The requirement for user interaction and limited privileges reduces the ease of exploitation somewhat but does not eliminate the threat, especially in environments where users may be less security-aware.

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.
