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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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 14 Oct 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

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 2026-10-25.

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

1. Apply SAP vendor patches immediately once they become available for the affected versions to remediate the NULL pointer dereference vulnerability. 2. Restrict network access to SAP NetWeaver AS ABAP and ABAP Platform servers by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3. Employ SAP Security Notes and regularly monitor SAP Support Portal for updates and advisories related to this vulnerability. 4. Enable and review SAP system logs and audit trails to detect anomalous or malformed SAP Logon or Assertion Ticket submissions indicative of exploitation attempts. 5. Implement intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting malformed SAP tickets or abnormal SAP protocol traffic. 6. Harden SAP application server configurations by disabling unnecessary services and enforcing strong authentication mechanisms for administrative access. 7. Conduct regular vulnerability assessments and penetration testing focused on SAP environments to identify and remediate exposure. 8. Develop and test incident response plans specifically addressing SAP system availability disruptions to minimize operational impact. 9. Educate SAP system administrators and security teams about this vulnerability and recommended defensive measures. 10. Consider deploying SAP Enterprise Threat Detection tools to enhance real-time monitoring and threat hunting capabilities within SAP landscapes.

Description

CVE-2025-42902 is a medium severity vulnerability in SAP NetWeaver AS ABAP and ABAP Platform that allows an unauthenticated attacker to cause a NULL pointer dereference by sending a corrupted SAP Logon or Assertion Ticket. This triggers a crash of the SAP work process, impacting availability but not confidentiality or integrity. The vulnerability affects multiple versions of SAP NetWeaver and ABAP Platform, including widely used releases such as 7.22, 7.53, 7.54, 7.77, 7.89, 7.93, and 9.x series.

Impact

For European organizations, the primary impact of CVE-2025-42902 is a potential denial of service (DoS) condition on SAP NetWeaver AS ABAP and ABAP Platform servers. This can disrupt business-critical applications such as ERP, supply chain management, and financial systems that rely on SAP infrastructure. Although the vulnerability does not compromise data confidentiality or integrity, availability interruptions can lead to operational downtime, financial losses, and reputational damage. Industries with high SAP dependency, including manufacturing, automotive, pharmaceuticals, and financial services, are particularly vulnerable. Given the unauthenticated remote exploitability, attackers could target exposed SAP servers to cause service outages. This risk is heightened in environments with insufficient network segmentation or weak access controls. The impact is compounded in organizations with limited incident response capabilities or delayed patch management processes. Additionally, regulatory compliance frameworks in Europe, such as GDPR, emphasize service availability and operational resilience, making mitigation of such vulnerabilities critical.

Base weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #13OWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product dereferences a pointer that it expects to be valid but is NULL.
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
Requirements
Select a programming language that is not susceptible to these issues.
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
