CVE-2021-41320 describes a vulnerability in Wallstreet Suite TRM version 7.4.83 (64-bit edition), where a technical user account is configured with hardcoded credentials that possess higher privileges than an average authenticated user. This means that the credentials for this privileged account are embedded in the software, potentially allowing an attacker who discovers these credentials to gain elevated access rights. However, the vendor disputes the characterization of these credentials as hardcoded, stating that the password can be changed during installation or at any later time, which would mitigate the risk of static credential exposure. The vulnerability has a CVSS 3.1 base score of 5.5, indicating a medium severity level. The vector indicates that the attack requires low attack complexity (AC:L), local attack vector (AV:L), no impact on availability (A:N), high impact on confidentiality (C:H), no impact on integrity (I:N), privileges required are low (PR:L), scope is unchanged (S:U), and no user interaction is needed (UI:N). This suggests that an attacker with some level of local access and low privileges could exploit this vulnerability to gain access to sensitive information without needing to trick a user or cause system disruption. The lack of known exploits in the wild and absence of patch links indicate that this vulnerability may be under limited active exploitation or that remediation guidance is not widely published. Overall, the issue centers on the risk posed by privileged credentials that may be static or insufficiently protected, which could be leveraged for unauthorized data access or lateral movement within affected systems.

For European organizations using Wallstreet Suite TRM 7.4.83, this vulnerability could lead to unauthorized disclosure of sensitive financial or transactional data due to the high confidentiality impact. Since the privileged account has elevated rights, an attacker exploiting this flaw could access critical information or potentially escalate privileges further. The local attack vector means that attackers would need some form of access to the internal network or system, which could be achieved via compromised user accounts or insider threats. The medium severity reflects that while the vulnerability does not directly affect system availability or integrity, the confidentiality breach could have significant regulatory and reputational consequences, especially under GDPR and other European data protection laws. Financial institutions and organizations handling sensitive market or transaction risk management data would be particularly at risk, as exposure of such data could lead to financial loss, regulatory penalties, and erosion of client trust. The vendor's claim that the password can be changed reduces the risk if organizations have implemented proper installation and credential management practices. However, failure to do so could leave systems vulnerable to exploitation.

European organizations should first verify whether the privileged technical user account password has been changed from any default or installation-time value. Implement strict credential management policies that enforce immediate password changes during installation and regular rotation thereafter. Conduct thorough audits to identify any instances of default or weak credentials in the Wallstreet Suite TRM environment. Limit local access to systems running this software to trusted personnel only, and employ network segmentation to reduce the attack surface. Implement robust monitoring and alerting for unusual access patterns or privilege escalations related to the technical user account. If possible, request or develop patches or updates from the vendor that remove or better secure the privileged account credentials. Additionally, consider deploying multi-factor authentication for administrative access to further reduce the risk of credential misuse. Finally, ensure that incident response plans include scenarios involving credential compromise to enable rapid containment and remediation.
