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: None: The vulnerable system can be exploited without any interaction from any user.
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).

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Mar 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

1. Immediately change any default passwords on Dell SmartFabric OS10 devices to strong, unique credentials. 2. Restrict remote access to management interfaces by implementing network segmentation, VPNs, or IP whitelisting to limit exposure. 3. Monitor network traffic and device logs for unusual authentication attempts or access patterns indicative of exploitation attempts. 4. Apply security best practices such as disabling unused services and enforcing multi-factor authentication if supported. 5. Stay informed on Dell’s security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 6. Conduct regular audits of device configurations to ensure no default credentials remain in use. 7. Implement network intrusion detection/prevention systems (IDS/IPS) tuned to detect attempts to exploit default credentials. 8. Educate network administrators about the risks of default passwords and enforce policies to prevent their use in production environments.

Description

Dell SmartFabric OS10 Software, version(s) 10.5.4.x, 10.5.5.x, 10.5.6.x, 10.6.0.x, contain(s) an Use of Default Password vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.

Impact

The impact of CVE-2024-49559 is significant for organizations using Dell SmartFabric OS10 in their network infrastructure. Exploitation can lead to unauthorized access to network devices, allowing attackers to manipulate network traffic, disrupt services, or exfiltrate sensitive data. This can result in widespread network outages, data breaches, and loss of trust. Given that SmartFabric OS10 is often deployed in enterprise data centers and cloud environments, the vulnerability could affect critical infrastructure and services. The compromise of network fabric devices can also facilitate lateral movement within an organization’s network, escalating the severity of attacks. The high CVSS score indicates that the vulnerability affects confidentiality, integrity, and availability severely, with low complexity and no user interaction required, increasing the likelihood of exploitation. Organizations without proper network segmentation or access controls are at higher risk. The absence of known exploits in the wild currently provides a window for proactive defense, but the threat remains urgent due to the nature of the vulnerability.
