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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Jun 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

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 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 this vulnerability, European organizations should first ensure that only trusted and necessary users have authenticated access to the IBM Verify Identity Access Digital Credentials service, minimizing the risk of exploitation by limiting the attack surface. Implement strict access controls and monitor authentication logs for unusual POST request patterns that could indicate attempts to exploit this vulnerability. In the interim, consider deploying application-layer firewalls or intrusion prevention systems (IPS) with custom rules to detect and block malformed POST requests targeting this service. Additionally, implement robust service monitoring and automated restart mechanisms to reduce downtime in case of a crash. Regularly review and update incident response plans to include scenarios involving identity service outages. Finally, conduct thorough testing in staging environments before applying any updates or configuration changes to avoid unintended service disruptions.

Description

IBM Verify Identity Access Digital Credentials 24.06 could allow an authenticated user to crash the service with a specially crafted POST request.

Impact

For European organizations, the impact of CVE-2024-56343 primarily concerns service availability. IBM Verify Identity Access Digital Credentials is used to manage digital identities and access controls, which are critical components in enterprise security infrastructure. A service crash could interrupt authentication and authorization processes, leading to operational downtime, delayed access to critical systems, and potential compliance issues, especially under stringent EU data protection regulations like GDPR that require continuous protection of identity data. Organizations relying heavily on IBM Verify for identity management may experience disruptions in user access, impacting productivity and possibly customer-facing services. Although the vulnerability requires authenticated access, insider threats or compromised credentials could be exploited to trigger the crash, amplifying risk. Additionally, the disruption could be used as a diversion tactic in multi-stage attacks. Given the central role of identity services, even temporary unavailability can have cascading effects on business continuity and security monitoring.

CWE-771Missing Reference to Active Allocated Resource (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product does not properly maintain a reference to a resource that has been allocated, which prevents the resource from being reclaimed.
Operation · Architecture and Design · Resource Limitation
Use resource-limiting settings provided by the operating system or environment. For example, when managing system resources in POSIX, setrlimit() can be used to set limits for certain types of resources, and getrlimit() can determine how many resources are available.
