1. Risk Assessment
The vulnerability identified as CVE-2024-27275 is a local privilege escalation flaw in IBM i versions 7.2, 7.3, 7.4, and 7.5. It arises from insufficient authority requirements, allowing a local user without administrative privileges to configure a physical file trigger. This trigger can execute with the privileges of a user who is socially engineered to access the target file. The CVSS v3.1 base score of 7.4 (HIGH) reflects the significant risk posed by this vulnerability.
The nature of this vulnerability is particularly concerning because it enables privilege escalation, which can lead to unauthorized access to sensitive data, system manipulation, and disruption of services. The attack complexity is high, meaning exploitation requires specific conditions and knowledge, but the impact on confidentiality, integrity, and availability is severe. An attacker could gain full control over the affected system, leading to data breaches, system compromise, and potential downtime.
The likelihood of exploitation is moderate, given the need for local access and social engineering. However, the potential business impact is high, as successful exploitation could result in significant financial, reputational, and operational damage. Organizations relying on IBM i systems for critical operations should treat this vulnerability as a priority.
2. Potential Attack Scenarios
A potential attack scenario involves a malicious insider or an attacker who has gained local access to an IBM i system. The attacker identifies a target user with elevated privileges and crafts a social engineering campaign to trick the user into accessing a specific file. Once the user accesses the file, the attacker exploits the vulnerability by configuring a physical file trigger. This trigger executes malicious code with the privileges of the targeted user, granting the attacker administrative control over the system.
The attack process begins with the attacker gaining local access to the system, either through compromised credentials or physical access. The attacker then identifies a high-privilege user and uses social engineering tactics, such as phishing or pretexting, to lure the user into accessing a manipulated file. Once the file is accessed, the trigger executes, and the attacker gains elevated privileges. The potential outcomes include unauthorized access to sensitive data, system configuration changes, and disruption of critical services.
3. Mitigation Recommendations
To mitigate this vulnerability, organizations should immediately apply the relevant patches provided by IBM. The correction requires administrator privileges to configure trigger support, effectively closing the loophole. Administrators should review and update user access controls to minimize the risk of privilege escalation.
Additionally, organizations should implement robust social engineering awareness training for employees to reduce the likelihood of successful exploitation. Regular security audits and monitoring of system logs can help detect and respond to suspicious activities.

1. Risk Assessment
The vulnerability, CVE-2024-35122, represents a low-severity local denial of service condition in IBM i versions 7.2, 7.3, 7.4, and 7.5. The core issue is an insufficient authority requirement when configuring referential constraints, allowing a local, non-privileged user to trigger a DoS. The vulnerability’s business impact is moderate; while not catastrophic, it can disrupt operations for users affected by the DoS, potentially impacting productivity and service availability. The likelihood of exploitation is moderate, as it requires social engineering to obtain privileges from a user who can access the target file, but doesn’t require complex technical skills. Ease of exploitation is also moderate, requiring a locally authenticated user with some familiarity with IBM i configuration. The vulnerability primarily impacts availability, causing a denial of service at the file level. Confidentiality and integrity are not directly impacted, though a prolonged DoS could indirectly affect data integrity if processes are interrupted mid-write. The EPSS score of 0.000250000 suggests a relatively low probability of exploitation in the wild.
2. Potential Attack Scenarios
A potential attack scenario involves a disgruntled or socially engineered IBM i user. An attacker could socially engineer a user with sufficient privileges to configure referential constraints on a target file. The attacker, a local non-privileged user, then leverages those privileges (obtained through the social engineering) to configure the constraint in a way that causes a localized denial of service when accessing the file. This could manifest as slowed performance or outright inability to access the target file for other users. The attack vector is local, requiring access to the IBM i system. The attack process involves gaining the privileges through social engineering, then configuring the referential constraint. The potential outcome is a denial of service impacting the target file's availability, potentially disrupting applications or processes relying on that file.
3. Mitigation Recommendations
The primary mitigation is to apply the patch provided by IBM. Refer to IBM support page https://www.ibm.com/support/pages/node/7178317 for the latest patch and installation instructions. In the interim, review and restrict the privileges granted to users who can configure referential constraints. Implement least privilege principles, ensuring users only have the necessary permissions to perform their tasks. Consider monitoring for unusual referential constraint configurations. Educate users on potential social engineering tactics to minimize the likelihood of privilege escalation. Regularly audit user permissions and access controls.
4. Executive Summary
IBM i versions 7.2 through 7.5 are susceptible to a localized denial of service vulnerability (CVE-2024-35122). A local user, with some assistance via social engineering, can cause a disruption in service at the file level. While the vulnerability is considered low-severity, a denial of service can impact user productivity and potentially disrupt critical business processes. We recommend applying the patch from IBM as soon as possible to mitigate this risk. In the meantime, review user privileges and educate users on social engineering threats.
