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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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 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.

AI-suggested

Implement strict access controls on IBM i systems to limit authenticated user privileges to only those necessary, reducing the risk of misuse.
Apply network segmentation to isolate IBM i systems from sensitive internal services, minimizing the impact of SSRF-induced requests.
Monitor outbound traffic from IBM i systems for unusual or unauthorized requests, using intrusion detection systems or network monitoring tools.
Enforce strong authentication mechanisms and regularly audit user accounts to prevent credential compromise.
Restrict the IBM i system’s ability to initiate network connections to only trusted destinations via firewall rules or host-based controls.
Stay informed about IBM’s security advisories and apply patches promptly once available.
Conduct regular security assessments and penetration tests focusing on SSRF and related vulnerabilities within the IBM i environment.
Educate system administrators about SSRF risks and encourage vigilance for suspicious system behavior or logs.

Description

IBM i 7.3, 7.4, and 7.5 is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

Impact

For European organizations, the impact of CVE-2024-51463 can be substantial, especially in sectors relying heavily on IBM i systems such as finance, manufacturing, and government services. The SSRF vulnerability allows attackers to bypass perimeter defenses by leveraging the trusted position of the IBM i system within internal networks. This can lead to unauthorized access to sensitive internal services, potentially exposing confidential data or enabling further exploitation chains. The integrity of internal communications may be compromised if attackers manipulate requests to internal APIs or services. Although availability is not directly affected, the indirect consequences of successful exploitation could disrupt business operations. The requirement for authentication limits the attack surface but does not eliminate risk, particularly if credential theft or insider threats are present. European organizations with complex network architectures and interconnected systems may find it challenging to detect and contain SSRF exploitation without proper monitoring and segmentation.
