CVE-2025-26662 is a medium-severity vulnerability classified under CWE-79, which pertains to improper neutralization of input during web page generation, commonly known as Cross-Site Scripting (XSS). This vulnerability affects the SAP Data Services Management Console, specifically version SBOP DS JOB SERVER 4.3. The root cause is insufficient encoding of user-controlled inputs within the web interface of the management console. An attacker can exploit this by crafting a malicious link containing injected script code. When a victim, who must already be authenticated and logged into the SAP Data Services Management Console, clicks on this link, the malicious script executes within the context of the victim's browser session. This execution can lead to unauthorized disclosure or modification of sensitive information accessible through the console, impacting confidentiality and integrity. However, the vulnerability does not affect system availability. The CVSS 3.1 base score is 4.4, reflecting the need for user interaction (clicking the malicious link), a requirement for low privileges (logged-in user), and a high attack complexity due to the need for a crafted link and user action. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's scope is confined to the SAP Data Services Management Console environment, which is typically used for data integration and management tasks within enterprise environments.

For European organizations using SAP Data Services Management Console SBOP DS JOB SERVER 4.3, this vulnerability poses a risk primarily to the confidentiality and integrity of data managed through this platform. Attackers exploiting this XSS flaw could hijack authenticated sessions, steal sensitive data, or perform unauthorized actions within the console under the victim's credentials. This can lead to data leakage, unauthorized data manipulation, or further pivoting within the network. Given the critical role of SAP Data Services in data processing and integration, such breaches could disrupt business operations, lead to compliance violations (e.g., GDPR), and damage organizational reputation. The requirement for the victim to be logged in and to click a malicious link somewhat limits the attack surface but does not eliminate risk, especially in environments with many users or where phishing attacks are common. The absence of availability impact means operational continuity is less likely to be affected directly, but indirect effects from data compromise could still be significant.

European organizations should implement the following specific mitigations: 1) Immediately review and restrict access to the SAP Data Services Management Console to only necessary personnel, enforcing the principle of least privilege. 2) Educate users about phishing risks and the dangers of clicking unsolicited links, especially when logged into critical systems. 3) Monitor and log user activities on the console to detect unusual behavior that may indicate exploitation attempts. 4) Apply strict Content Security Policy (CSP) headers on the management console web interface to limit the execution of unauthorized scripts. 5) Use web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting SAP consoles. 6) Stay alert for official SAP patches or updates addressing CVE-2025-26662 and apply them promptly once available. 7) Conduct regular security assessments and penetration testing focused on web interfaces of SAP products to identify and remediate similar input validation issues proactively.
