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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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.

What to do

AI-suggested

Apply SAP security patches or updates as soon as they become available for the affected SAP HCM My Timesheet Fiori 2.0 application version GBX01HR5 605.
Conduct a thorough review of user roles and permissions within SAP HCM to ensure the principle of least privilege is enforced, minimizing the number of users with elevated privileges.
Implement strict access control policies and monitor for anomalous privilege escalation activities or unauthorized modifications to timesheet data.
Use SAP's security audit logs and monitoring tools to detect suspicious behavior related to timesheet entries or privilege changes.
Restrict network access to the SAP HCM application to trusted internal networks or VPNs to reduce exposure to external attackers.
Educate users about the importance of safeguarding their credentials to prevent account compromise.
Consider implementing multi-factor authentication (MFA) for SAP HCM access to reduce the risk of unauthorized access.
Regularly review and update authorization checks in custom SAP Fiori applications to prevent similar issues.
Engage with SAP support and security advisories to stay informed about patches and best practices related to this vulnerability.

Description

SAP HCM My Timesheet Fiori 2.0 application does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges. This issue has a significant impact on the application's integrity, while confidentiality and availability remain unaffected.

Impact

The primary impact of CVE-2025-42912 is on the integrity of the SAP HCM My Timesheet application data. Unauthorized privilege escalation can lead to unauthorized modification of timesheet records, which can disrupt payroll accuracy, compliance with labor regulations, and internal auditing processes. This can result in financial losses, legal liabilities, and damage to organizational trust. Since confidentiality and availability are unaffected, the risk of data leakage or service disruption is low. However, the integrity compromise can have cascading effects on HR operations and employee trust. Organizations relying heavily on SAP HCM for workforce management, especially those with complex payroll and compliance requirements, face significant operational risks if this vulnerability is exploited. Attackers with authenticated access, such as disgruntled employees or compromised accounts, could abuse this flaw to manipulate records undetected. The absence of known exploits in the wild provides a window for remediation, but the vulnerability's nature makes it a high priority for patching and mitigation.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
