CVE-2025-31324 Scanner

SAP NetWeaver is a software platform widely used by businesses for web service-based integration of business processes. Many enterprises rely on it to ensure smooth and cohesive operation across different software applications. SAP NetWeaver is developed and maintained by SAP SE. It is commonly utilized in diverse sectors, ranging from finance to logistics, to streamline digital business functions. The platform allows seamless data integration and management, supporting the development of complex applications. SAP NetWeaver's versatility and extensive capabilities make it integral to businesses aiming for optimized operational efficiencies.

Deserialization of untrusted data is a vulnerability that can allow attackers to execute arbitrary code, consequently compromising system integrity. This vulnerability is particularly dangerous in systems where user-supplied data is deserialized without proper checks. If not managed adequately, this exposure can lead to unauthorized data manipulation or system control by an attacker. It poses a critical risk by potentially allowing exploitation with minimal access prerequisites. The vulnerability affects critical aspects such as confidentiality, integrity, and availability of the system. Preventative measures and stringent input validation are essential for management.

Technical details reveal that the vulnerable endpoint is the metadata uploader of SAP NetWeaver where unvalidated data could be uploaded. Without proper authorization checks, malicious input could be submitted to the system. This data, when deserialized improperly, may execute rogue code, disrupting services or exposing sensitive data. The deserialization endpoint prone to this flaw typically does not sanitize inputs before processing, thereby enhancing the risk. Attackers exploiting this vulnerability could bypass protection measures, leading potentially to a full system breach. Such compromises can have far-reaching impacts across integrated services and processes.

The exploitation of the deserialization vulnerability could result in unauthorized execution of commands on SAP NetWeaver. The potential effects are wide-ranging, including the deployment of malicious software or capturing control over the system. Confidential data may be extracted, modified, or deleted by unauthorized entities. Business operations can be disrupted significantly, affecting data availability and integrity. Moreover, reliance on compromised data can misguide decision-making processes, leading to substantial operational risk. Damage may extend to the organization's reputation, especially if customer data is implicated.
