CVE-2025-26662 is a cross-site scripting (XSS) vulnerability classified under CWE-79, affecting SAP Data Services Management Console, specifically version SBOP DS JOB SERVER 4.3. The root cause is insufficient encoding of user-controlled inputs during web page generation, which allows attackers to inject malicious JavaScript code. When an authenticated user clicks a maliciously crafted link, the injected script executes within the victim's browser session, inheriting the privileges of the logged-in user. This can lead to unauthorized disclosure or modification of sensitive data accessible through the console, impacting confidentiality and integrity. The vulnerability does not affect system availability. The CVSS v3.1 score is 4.4 (medium), reflecting network attack vector, high attack complexity, low privileges required, and mandatory user interaction. No public exploits have been reported yet, but the vulnerability is publicly disclosed and should be addressed promptly. The vulnerability is particularly concerning in environments where SAP Data Services Management Console is used to manage critical data workflows, as attackers could leverage XSS to perform session hijacking, credential theft, or unauthorized actions within the console interface.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of data managed via SAP Data Services Management Console. Attackers exploiting this flaw could steal session tokens, manipulate data, or perform actions on behalf of legitimate users, potentially leading to data breaches or unauthorized data modifications. Although availability is not impacted, the breach of sensitive business data or intellectual property could have severe financial and reputational consequences. Organizations in sectors such as finance, manufacturing, and critical infrastructure that rely heavily on SAP Data Services for data integration and management are particularly vulnerable. The requirement for user interaction and authentication reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, especially spear-phishing campaigns aimed at privileged users.

To mitigate this vulnerability, organizations should apply SAP-provided patches or updates as soon as they become available. In the absence of patches, implement strict input validation and output encoding on all user inputs within the SAP Data Services Management Console to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the console. Enhance user awareness and training to recognize and avoid clicking suspicious links, especially for users with access to the console. Monitor logs for unusual activities indicative of XSS exploitation attempts. Additionally, consider isolating the management console behind VPNs or secure gateways to limit exposure to external threats. Regularly review and minimize user privileges to reduce the impact of potential compromises.
