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

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

What to do

AI-suggested

Implement network-level protections such as ingress filtering and rate limiting to detect and block abnormal TCP traffic patterns targeting SunOS Omnios systems.
Deploy intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics to identify crafted TCP packets indicative of this attack.
Isolate vulnerable systems from direct exposure to untrusted networks, using firewalls or network segmentation to limit attack surface.
Monitor system logs and network traffic for signs of repeated TCP packet anomalies or service disruptions.
Engage with the vendor or community maintaining SunOS Omnios for patches or updates addressing this vulnerability and apply them promptly once available.
Consider migrating critical services off SunOS Omnios v5.11 to more actively maintained platforms if feasible.
Prepare incident response plans specifically for DoS scenarios affecting legacy Unix systems to minimize downtime.
Use TCP stack hardening techniques or kernel-level mitigations if supported by the OS to reduce susceptibility to crafted packet attacks.

Description

An issue in SunOS Omnios v5.11 allows attackers to cause a Denial of Service (DoS) via repeatedly sending crafted TCP packets.

Impact

For European organizations, the primary impact of CVE-2024-57412 is the potential for Denial of Service attacks that disrupt availability of systems running SunOS Omnios v5.11. This can lead to downtime of critical infrastructure, loss of business continuity, and operational disruptions, especially in sectors relying on legacy Unix systems such as telecommunications, finance, and industrial control. Since the vulnerability can be exploited remotely without authentication, attackers can launch DoS attacks from anywhere, increasing the risk of widespread disruption. Although confidentiality and integrity are not directly affected, the loss of availability can indirectly impact service delivery and trust. Organizations with limited capacity to quickly patch or replace affected systems face higher risk. The lack of known exploits in the wild currently reduces immediate threat but does not eliminate the risk of future exploitation. European entities with regulatory requirements for uptime and incident response must prioritize mitigation to avoid compliance issues and reputational damage.

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
