CVE-2025-0057 is a medium-severity stored cross-site scripting vulnerability affecting SAP NetWeaver AS JAVA, specifically the User Admin Application. This vulnerability allows attackers who pose as administrators to upload malicious JavaScript content embedded in images. When victims access the compromised component, the attacker can exploit this vulnerability to read and modify sensitive information within the victim's web browser.
With a CVSS score of 4.8, this vulnerability indicates a medium level of severity. The risk to organizations includes unauthorized access to user data and potential manipulation of that data when users interact with the compromised web application. Given the potential impact, it is crucial for organizations to address this vulnerability in their patch cycle.
As of now, there is no public exploit available or confirmed for this vulnerability, which provides a window for organizations to remediate the issue before it can be actively exploited. Organizations should prioritize patching immediately to eliminate the risk of exploitation.
SAP has classified the status of this vulnerability as deferred, indicating that while the issue has been recognized, it may not yet have a patch available. Organizations should continue to monitor for updates related to this vulnerability and take proactive steps to secure their applications.
Vulnerability Details
The official description of CVE-2025-0057 from SAP states: 'SAP NetWeaver AS JAVA (User Admin Application) is vulnerable to stored cross site scripting vulnerability. An attacker posing as an admin can upload a photo with malicious JS content. When a victim visits the vulnerable component, the attacker can read and modify information within the scope of the victim's web browser.'
The CVSS score for this vulnerability is 4.8, categorized as medium severity. This classification reflects the potential impact of the vulnerability if exploited, specifically in terms of confidentiality and integrity, as both are rated low. The attack vector is categorized as network-based, requiring high privileges and user interaction.
The CWE classification associated with this vulnerability is CWE-434, which pertains to the improper handling of file uploads.
Technical Analysis
The root cause of this vulnerability is related to insufficient input validation and sanitization of uploaded content. Attackers can exploit this weakness by uploading a file containing malicious JavaScript, which is then executed in the context of the victim's browser when they access the affected application.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely over the internet. The attack complexity is classified as low, requiring only basic knowledge of the application and its file upload functionality.
This vulnerability requires high privileges, as the attacker must be able to impersonate an administrator to upload the malicious content. User interaction is also required, as the victim must visit the affected component for the attack to succeed.
In terms of impact, the confidentiality and integrity of the data are both rated low, indicating that while unauthorized access and modification are possible, the overall impact may be limited to the specific application context. There is no impact on availability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0057 is significant, particularly for organizations that utilize SAP NetWeaver AS JAVA in environments where user interaction is common. Given that attackers can exploit the vulnerability to manipulate user data, organizations face potential reputational harm and data integrity issues.
The blast radius for this vulnerability can extend beyond the immediate application, potentially affecting other interconnected systems and processes. Organizations should assess their risk exposure and prioritize this vulnerability in their remediation efforts.
Based on the CVSS score of 4.8, organizations should schedule remediation within their priority patch cycle. The urgency for patching is moderate, especially given the potential for exploitation if the vulnerability becomes public or if an exploit is developed.
