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: None: There is no loss of confidentiality within the impacted component.
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.

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 30 Oct 2026.

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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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

To mitigate CVE-2026-23817, organizations should first ensure that access to the HPE AOS-CX web management interface is restricted to trusted networks and users only, ideally via network segmentation and firewall rules. Implementing VPN or jump hosts for management access can reduce exposure. Administrators should monitor HPE advisories closely for patches or updates addressing this vulnerability and apply them promptly once available. In the interim, consider disabling web-based management if feasible or limiting its use. Employ web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) to detect and block suspicious redirection attempts targeting the management interface. User education is critical; train administrators to recognize and avoid suspicious links or unexpected redirects when accessing management consoles. Logging and monitoring of management interface access should be enhanced to detect anomalous activities. Additionally, enforcing strong authentication and multi-factor authentication (MFA) on management interfaces can reduce the risk of follow-on attacks if redirection is exploited. Regular security assessments and penetration testing of network management infrastructure can help identify and remediate related weaknesses.

Description

A vulnerability in the web-based management interface of AOS-CX Switches could allow an unauthenticated remote attacker to redirect users to an arbitrary URL.

Impact

The primary impact of CVE-2026-23817 is on the integrity of the HPE AOS-CX switch management interface sessions. By enabling arbitrary URL redirection, attackers can trick users into visiting malicious websites, potentially leading to phishing attacks, credential theft, or malware distribution. Although the vulnerability does not directly compromise confidentiality or availability, the indirect consequences of successful phishing or social engineering could lead to broader network compromise or data breaches. Organizations relying on HPE AOS-CX switches for critical network infrastructure may face increased risk of targeted attacks exploiting this vulnerability to gain footholds or disrupt operations. The ease of exploitation without authentication and the network-accessible nature of the management interface increase the threat surface. However, the requirement for user interaction limits automated exploitation. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks. Overall, the vulnerability poses a moderate risk to organizations with exposed or poorly secured management interfaces, especially in sectors where network integrity is critical.

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.
