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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Mar 2024
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 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

Restrict network access to FastDDS endpoints by implementing strict firewall rules and network segmentation to limit exposure to untrusted sources.
Monitor FastDDS processes for abnormal terminations and implement automated restart mechanisms to minimize downtime.
Employ application-layer filtering or validation to detect and block malformed or suspicious DataWriter messages that could trigger the SIGABRT.
Engage with the FastDDS community or vendor for updates and patches addressing this vulnerability as they become available.
Conduct thorough testing of FastDDS deployments under load and malformed input conditions to identify and mitigate potential crash triggers.
Where possible, isolate critical FastDDS components in hardened environments with minimal external exposure.
Implement logging and alerting for unusual network activity or process crashes to enable rapid incident response.
Consider alternative DDS implementations or versions not affected by this vulnerability if immediate patching is not feasible.

Description

An issue in the HistoryQosPolicy component of FastDDS v2.12.x, v2.11.x, v2.10.x, and v2.6.x leads to a SIGABRT (signal abort) upon receiving DataWriter's data.

Impact

The primary impact of CVE-2024-26369 is denial of service caused by unexpected process termination (SIGABRT) in FastDDS applications. This can disrupt real-time data exchange in distributed systems, leading to operational downtime, loss of data continuity, and potential safety risks in critical environments like automotive, aerospace, and industrial control systems. The high confidentiality impact suggests that sensitive data might be exposed or improperly handled during the crash, increasing the risk of information leakage. Organizations relying on FastDDS for mission-critical communication may experience degraded system reliability and increased operational costs due to system restarts and troubleshooting. The lack of required privileges or user interaction for exploitation means attackers can remotely trigger the vulnerability, increasing the attack surface and risk of widespread disruption. Although no known exploits exist yet, the vulnerability's characteristics make it a likely target for attackers aiming to cause service outages or gather sensitive information by exploiting the crash behavior.

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.
