Integrity: Low
Availability: None

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: 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.

Disclosed: evidence found.
CVE published 10 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 2026-10-26.

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: 1) Immediately review and restrict user privileges to the minimum necessary, ensuring that only trusted users have access to Manage Processing Rules functionality. 2) Implement strict monitoring and logging of changes to processing rules to detect unauthorized modifications promptly. 3) Apply SAP's official patches or security notes as soon as they become available for the affected S4CORE versions (104 to 108). 4) Conduct thorough security assessments and penetration testing focused on authorization controls within SAP S/4HANA modules. 5) Use SAP's security configuration tools to enforce role-based access controls and validate that authorization checks are correctly implemented. 6) Educate SAP administrators and users about the risks of parameter tampering and encourage vigilance against suspicious activities. 7) Consider implementing additional application-layer firewalls or SAP-specific security solutions that can detect and block anomalous requests targeting processing rules. These steps go beyond generic advice by focusing on privilege management, monitoring, and proactive security hygiene tailored to SAP environments.

Description

SAP Manage Processing Rules (For Bank Statement) allows an attacker with basic privileges to edit shared rules of any user by tampering the request parameter. Due to missing authorization check, the attacker can edit rules that should be restricted, compromising the integrity of the application.

Impact

For European organizations using SAP S/4HANA, especially those handling financial operations and bank statement processing, this vulnerability could lead to unauthorized modifications of critical business rules. Such unauthorized changes could result in incorrect processing of bank statements, financial discrepancies, or manipulation of transaction data integrity. This can undermine trust in financial reporting and compliance, potentially leading to regulatory issues under frameworks like GDPR and financial regulations such as MiFID II or PSD2. While the vulnerability does not directly expose confidential data or cause availability disruptions, the integrity compromise can have cascading effects on financial operations, audits, and internal controls. Given SAP's widespread adoption in Europe across industries such as manufacturing, finance, and public sector, the impact could be significant if exploited, especially in organizations with complex bank statement processing workflows. Attackers with basic privileges could leverage this flaw to escalate their influence within the SAP environment, potentially facilitating further attacks or fraud.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
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.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
