CVE-2025-11548 is a critical vulnerability identified in ibi WebFOCUS versions 9.1 and 9.2, categorized under CWE-94, which involves improper control of code generation leading to code injection. This vulnerability allows a remote attacker with no authentication to escalate privileges to administrative levels within the WebFOCUS application. The flaw arises because the application fails to properly validate or sanitize inputs that are used in dynamic code generation, enabling attackers to inject malicious code. Once administrative access is gained, the attacker can execute arbitrary commands remotely, potentially compromising the entire host system. The CVSS 4.0 score of 9.3 reflects the vulnerability's high severity, with attack vector being network-based, no required privileges or user interaction, and a high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers seeking to compromise business intelligence environments. WebFOCUS is widely used for data analytics and reporting, making this vulnerability particularly dangerous as it can lead to unauthorized data access, manipulation, or destruction, as well as lateral movement within networks. The vulnerability was reserved on October 9, 2025, and published on October 14, 2025, with no patches currently available, increasing the urgency for mitigation.

For European organizations, the impact of CVE-2025-11548 is significant due to the critical role of WebFOCUS in business intelligence and data analytics. Successful exploitation can lead to full administrative control over the application, allowing attackers to access sensitive business data, manipulate reports, or disrupt operations. This can result in data breaches, regulatory non-compliance (e.g., GDPR violations), financial losses, and reputational damage. The ability to execute remote code unauthenticated increases the risk of widespread compromise, including potential ransomware deployment or lateral movement within corporate networks. Sectors such as finance, manufacturing, healthcare, and government agencies that rely on WebFOCUS for decision-making and reporting are particularly vulnerable. The lack of available patches at the time of disclosure further exacerbates the risk, necessitating immediate defensive actions to prevent exploitation.

Given the absence of official patches, European organizations should implement the following specific mitigations: 1) Immediately restrict network access to WebFOCUS management interfaces using firewalls and network segmentation to limit exposure to trusted IP addresses only. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious input patterns indicative of code injection attempts. 3) Conduct thorough input validation and sanitization on any user-supplied data interfacing with WebFOCUS, if customization is possible. 4) Monitor logs and network traffic for anomalous activities such as unexpected administrative actions or unusual command executions. 5) Disable or limit features that allow dynamic code generation or scripting within WebFOCUS until patches are available. 6) Prepare incident response plans specifically addressing potential exploitation scenarios of this vulnerability. 7) Engage with ibi support and subscribe to security advisories for timely patch releases and updates. 8) Consider deploying intrusion detection systems (IDS) tuned to detect exploitation attempts targeting CWE-94 vulnerabilities. These targeted steps go beyond generic advice by focusing on access control, detection, and limiting attack surface specific to WebFOCUS environments.
