CVE-2025-0252 is a vulnerability identified in HCL Software's IEM product, specifically version 1.2. The issue is classified under CWE-319, which pertains to the cleartext transmission of sensitive information. In this case, passwords or other sensitive credentials are transmitted over the network without adequate encryption or protection, making them susceptible to interception by unauthorized parties during transit. The vulnerability arises because the communication channels used by the affected version of HCL IEM do not sufficiently secure sensitive data, potentially allowing attackers with network access to capture these credentials through techniques such as packet sniffing or man-in-the-middle attacks. The CVSS v3.1 base score is 2.6, indicating a low severity level. The vector string (AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N) shows that the attack requires network access, high attack complexity, low privileges, and user interaction, with limited impact on confidentiality and no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability primarily affects the confidentiality of transmitted data but does not directly compromise system integrity or availability. Given that the vulnerability requires user interaction and low privileges, exploitation is less straightforward, reducing its immediate risk. However, the exposure of passwords in cleartext can facilitate further attacks if intercepted, such as unauthorized access or lateral movement within an organization’s network.

For European organizations using HCL IEM version 1.2, this vulnerability poses a risk of credential exposure during network transmission. If attackers gain access to the network segment where the vulnerable communications occur, they could capture passwords and potentially escalate privileges or access sensitive systems. This risk is heightened in environments where network segmentation or encryption is not enforced. Although the direct impact is limited to confidentiality and rated low severity, the potential for subsequent exploitation following credential compromise could lead to more severe consequences. Organizations in sectors with stringent data protection regulations, such as finance, healthcare, and critical infrastructure, may face compliance risks if sensitive credentials are exposed. Additionally, the requirement for user interaction and low privileges means that insider threats or targeted phishing campaigns could increase the likelihood of exploitation. Overall, while the immediate threat is low, the vulnerability could serve as an entry point for more complex attacks, especially in environments lacking robust network security controls.

To mitigate this vulnerability, European organizations should first verify if they are running HCL IEM version 1.2 and assess the extent of its deployment. Immediate steps include implementing network-level encryption such as TLS to protect all communications involving sensitive data, ensuring that no passwords or credentials are transmitted in cleartext. Network segmentation should be enforced to limit exposure of vulnerable communications to trusted segments only. Organizations should also monitor network traffic for signs of credential interception or unusual access patterns. User training to reduce risky interactions that could facilitate exploitation is recommended. Since no patches are currently available, consider applying compensating controls such as VPNs or secure tunnels for management traffic. Engage with HCL Software support to obtain updates on patch availability and apply them promptly once released. Finally, conduct regular security assessments and penetration tests focusing on credential transmission and network security to identify and remediate weaknesses proactively.
