CVE-2025-33079 is a medium-severity vulnerability affecting IBM Controller versions 11.0.0, 11.0.1, and 11.1.0. The vulnerability arises from the plaintext storage of passwords within the application source code, classified under CWE-256 (Plaintext Storage of a Password). Specifically, an authenticated user with legitimate access to the IBM Controller application can potentially extract sensitive credentials that are inadvertently embedded in the source code. This exposure does not require user interaction beyond authentication and can be exploited remotely over the network (AV:N). The vulnerability does not impact integrity or availability but has a high impact on confidentiality, as attackers can obtain sensitive credentials that may allow further unauthorized access or lateral movement within an environment. The CVSS 3.1 base score is 6.5, reflecting a medium severity level. The vulnerability is exploitable with low attack complexity (AC:L) and requires privileges (PR:L), meaning the attacker must already have some level of authenticated access to the system. No known exploits are currently reported in the wild, and no patches or remediation links have been published yet. The issue is significant because storing passwords in plaintext within source code violates security best practices and increases the risk of credential leakage if the source code is accessed by unauthorized parties or insiders. Given IBM Controller's role in enterprise environments for automation and orchestration, compromised credentials could lead to unauthorized access to critical business processes or infrastructure components.

For European organizations using IBM Controller versions 11.0.0 through 11.1.0, this vulnerability poses a tangible risk to confidentiality of sensitive credentials. If exploited, attackers with authenticated access could extract passwords and potentially escalate privileges or move laterally within the network. This could lead to unauthorized access to critical automation workflows, impacting business continuity and data security. The risk is heightened in regulated industries prevalent in Europe, such as finance, healthcare, and manufacturing, where data protection and operational integrity are paramount. Additionally, exposure of credentials could facilitate further attacks such as data exfiltration or sabotage. Although the vulnerability does not directly impact system integrity or availability, the indirect consequences of credential compromise could be severe. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially from insider threats or targeted attackers. European organizations with strict compliance requirements (e.g., GDPR) must consider the potential for data breaches resulting from this vulnerability and the associated legal and reputational consequences.

1. Immediate mitigation should include auditing IBM Controller deployments to identify affected versions (11.0.0, 11.0.1, 11.1.0) and restricting access to authenticated users to the minimum necessary privileges to reduce risk of credential exposure. 2. Organizations should conduct a thorough review of the IBM Controller source code and configuration files to identify and remove any plaintext passwords or sensitive credentials. 3. Implement secrets management solutions to securely store and retrieve credentials instead of embedding them in source code. 4. Monitor access logs and user activities within IBM Controller for unusual or unauthorized access patterns that could indicate exploitation attempts. 5. Enforce multi-factor authentication (MFA) for all users accessing IBM Controller to mitigate risks from compromised credentials. 6. Engage with IBM support channels to obtain official patches or updates addressing this vulnerability as they become available. 7. As a longer-term measure, incorporate secure coding practices and regular security code reviews to prevent plaintext credential storage in future software versions. 8. Consider network segmentation and strict firewall rules to limit exposure of IBM Controller interfaces to trusted networks only.
